Phytoremediation is an emerging low cost green technology, which uses plants for treating contaminant in the environment. Phytoremediation potential of locally available aquatic plants Eichhornia crassipes (water hyacinth), Pistia stratiotes (water lettuce) and Salvinia molesta (water fern) in the treatment process of textile wastewater was investi-gated. The reduction efficiencies of chemical oxygen demand (COD), total solids (TS), total suspended solids (TSS), total dissolved solids (TDS), nitrates, phosphates, heavy metals (Cd, Ni and Zn) and total and fecal coliform from the waste-water by each plant species were estimated. Bioconcentration factors (BCF) and translocation factors (TF) of three plant species for Cd, Ni and Zn were also estimated in order to identify their heavy metal absorption and translocation capacity. The results of the study indicated that greater reduction of COD, nitrates, phosphates, total coliform and Zn from the ini-tial wastewater by the three plant species. The results of the study also suggested that the selected aquatic plants are hy-peraccumulators of Cd, Ni and Zn metals. The findings of this study suggest that E. crassipes, P. stratiotes and S. molesta are potential aquatic plants for treating textile waste water.

The lack of clean water sources, due to the presence of pollutants in water, is a major issue in many countries, including Malaysia. To overcome this problem, various methods have been introduced, including phytoremediation treatment. Therefore, this phytoremediation study examined the ability of five aquatic plants—Centella asiatica, Ipomoea aquatica, Salvinia molesta, Eichhornia crassipes, and Pistia stratiotes—to remove three pollutants—total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and phosphate—from aquaculture wastewater. Using wastewater samples, each containing 50 g of one of the plants, the pollutant levels were measured every two days for 14 days. The results showed a drastic decline in the concentration of pollutants, where C. asiatica was able to remove 98% of NH3-N, 90% of TSS, and 64% of phosphate, while I. aquatica showed the potential to eliminate up to 73% of TSS and NH3-N, and 50% of phosphate. E. crassipes drastically removed 98% of phosphate, 96% of TSS, and 74% of NH3-N, while P. stratiotes was able to eliminate 98% of TSS, 78% of NH3-N, and 89% of phosphate. S. molesta was efficient in removing 89.3% of TSS and 88.6% of phosphate, but only removed 63.9% of NH3-N.

The adsorption of levafix red (LR) dye from waste water via batch adsorption onto treated jute stick powder was investigated. Studies concerning the factors influencing the adsorption such as adsorbent dosage, pH, contact time and temperature were systematically investigated and discussed. The results revealed that the maximum removal of levafix red was ~91% from water. The kinetics data were analyzed using pseudo-first order and pseudo-second order models. It was best described by the pseudo-second order model. The adsorption equilibrium follows Langmuir isotherm. This result indicates that treated jute stick powder could be employed as low-cost alternatives to commercial activated carbon for the removal of levafix red (LR) from waste water. Rapid industrialization in Bangladesh has resulted in increased water pollution that has higher dye level. Waste water from dyeing and finishing factories is a significant source of environmental pollution. The waste water is typically characterized by high levels of COD (chemical oxygen demand) concentration, high concentration of coloring material, large amount of suspended solids, highly fluctuating pH and high temperature. Dyes may therefore present an ecotoxic hazard and introduces the potential danger of bioaccumulation that may eventually affect man by transport through the food chain. As pharmaceutical industries use lots of water and intake of this type of water might have adverse effects on human health. Therefore, water purification is extremely essential for human and animal health and dye free water may be farther purified for its proper use.Bangladesh Pharmaceutical Journal 19(1): 75-84, 2016

The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, andHydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi-metals concentrations in mine waste water. The results show that theE. densaandH. verticillataare able to accumulate high amount of arsenic (95.2%) and zinc (93.7%) and resulted in a decrease of arsenic and zinc in the ambient water. On the other hand,C. piauhyensisshows remarkable aluminium accumulation in plant biomass (83.8%) compared to the other tested plants. The ability of these plants to accumulate the studied metals and survive throughout the experiment demonstrates the potential of these plants to remediate metal enriched water especially for mine drainage effluent. Among the three tested aquatic plants,H. verticillatawas found to be the most applicable (84.5%) and suitable plant species to phytoremediate elevated metals and metalloid in mine related waste water.

Textile effluent contains different organic and inorganic pollutants, among these are COD and heavy metals such as lead (Pb), chromium (Cr), cadium (Cd), and copper (Cu) used for the production of color pigments. In this study the adsorption capacity of chitosan produced from snail shells as an adsorbent for the treatment of textile effluent and for the removal of lead (Pb2+) from waste water carried out. Batch experiments were performed to study the treatment of textile waste water and the adsorption of lead Pb2+ion unto chitosan. The effect of various experimental parameters (adsorbent dose, contact time and temperature) was studied, and optimal conditions were determined. Batch adsorption study on textile waste water showed 96.9 % COD removal was achieved for carbon dosage of 15mg carbon/100ml of textile wastewater solution. The equilibrium data were analyzed with Langmuir, Freundlich, Temkin, Elovich, Florry Huggins, Jovanovic, Harkin Jura and Dubinin–Radushkevich (DRK) adsorption models. Freundlich isotherm yielded the best fit to the experimental equilibrium adsorption data with a correlation coefficient (R2 ) of 0.991. The adsorption intensity is 1.68. This was closely followed by Langmuir Isotherm with a correlation coefficient (R2 ) of is 0.943. The maximum monolayer coverage (Qo) from Langmuir isotherm model was determined to be 50.51mg/g, KL (Langmuir isotherm constant) is 0.00374L/mg, RL (the separation factor) is 0.217 indicating that the equilibrium sorption was favorable. Adsorption kinetics data for sorption of Pb2+ion unto chitosan were analyzed using the pseudo first order, pseudo second order and intra particle diffusion models. The results indicated that the adsorption kinetic data were best described by pseudo secondorder model. For the thermodynamic studies, the enthalpy change, ΔH°, and the entropy change, ΔS°, for the adsorption processes are -18.10 kJ/mol and -0.0652KJ/mol K respectively. The free energy, ΔG° for the process are 2186.39 J/mol, 3071.761 J/mol, 3689.615J/mol and 4153.032 J/mol at 303K, 313K, 323 K and 333K respectively. The results of thermodynamic parameters evaluated showed that the process was non spontaneous and exothermic in nature. The results show that chitosan can be used as an alternative low-cost adsorbent for treatment of textile effluent and the removal of COD and lead from wastewater.

Durante o ano de 1999 foram conduzidos três experimentos em Botucatu-SP, em condições de caixas d'água, com o objetivo de estudar o efeito de alguns herbicidas sobre Pistia stratiotes, Eichhornia crassipes e Salvinia molesta. Os herbicidas e as doses utilizadas foram: diquat a 460, 960 e 1.400 g ha-1 com e sem o surfatante Agral a 0,1%; 2,4 D a 1.340; glyphosate a 3.360 g ha-1 mais 0,5% do surfatante Aterbane; e imazapyr a 250 g ha-1, além de uma testemunha sem aplicação de herbicida. Os estudos foram instalados no delineamento experimental em blocos ao acaso, com quatro repetições. As parcelas experimentais foram constituídas por caixas d'água com dimensões de 60 x 60 x 60 cm mantidas a pleno sol no campo. Utilizaram-se 18, 18 e 30 plantas/caixa de P. stratiotes, E. crassipes e S. molesta, respectivamente. Os herbicidas foram aplicados com pulverizador costal a pressão constante de CO2 a 1,75 bar, munido de barra com bicos 110.02 VS, com consumo de calda de 180 L ha-1. O herbicida diquat foi eficiente no controle de S. molesta, P. stratiotes e E. crassipes em todas as doses testadas. Para P. stratiotes, os herbicidas 2,4 D e imazapyr não proporcionaram controle, enquanto o herbicida glyphosate mostrou-se eficiente. Em relação a E. crassipes, os herbicidas 2,4 D e glyphosate foram eficientes em seu controle. Os herbicidas imazapyr, 2,4 D e glyphosate não foram eficientes no controle de S. molesta.
