Remazol Brilliant Violet 5R

The ability of agricultural waste materials to remove synthetic dyes such as Remazol Brilliant Violet 5R (RBV-5R) and Remazol Brilliant Blue R (RBBR) from aqueous solutions was investigated. Dyes are a major source of water contamination that not only cause significant damage to water bodies but also have a negative effect on human health due to their high toxicity and carcinogenic nature. Agricultural wastes are renewable adsorbents because they are readily available and inexpensive, and they can also be used instead of conventional activated carbon. As a result, the removal of RBV-5R and RBBR from dye solutions by adsorption onto treated adsorbent was investigated in this review. The two best adsorbents out of ten were selected via a screening process with RBBR as the test dye. The key adsorbents in this analysis were coconut shells and mango seeds, which had the highest removal rate as compared to others. The experiment was continued with the chosen adsorbent to see how different initial dye concentrations, adsorbent dosage, contact time, pH, and particle size affected dye adsorption. The results show that different parameters have different effects on the removal rate and adsorption potential of the adsorbent. The adsorption of dye from aqueous solution onto adsorbent was investigated using Fourier transform infrared spectroscopy (FTIR) to investigate the functional groups of the adsorbent before and after the adsorption operation, and it was discovered that the functional group affected the effectiveness or removal rate as well as the adsorption capability of adsorbents. According to the findings, 5 gram mango seeds can extract 85.54 percent of RBV-5R with adsorption power of 1.26 mg/g. For 21 hours, coconut shells removed 74.39 percent of RBBR with an adsorption capacity of 8.01 mg/g. The findings indicated that these agricultural wastes could be useful as an alternative adsorbent for removing dye from aqueous solutions.

The potential of agricultural waste materials for the removal of synthetic dye, Phenol Red (PR) and Remazol Brilliant Blue R (RBBR) from aqueous solution was investigated. One of the major pollutants of water pollution, dyes, which not only result in enormous damage to the water body but also impact the organism's health, as it is highly toxic and carcinogenic by nature. Agricultural wastes are sustainable adsorbents since they are availability and low cost, which can also replace the traditional activated carbon. Therefore, this study investigated the removal of PR and RBBR from dye solution by adsorption onto the treated adsorbent. Two best out of ten adsorbents were chosen through a screening process using RBBR as a tested dye. Coconut shells (Cocos nucifera) and ambarella peels (Spondias dulcis) were selected as the main adsorbent of this study since they achieved the highest removal rate compared to others. With the selected adsorbent, the experiment was continued to study the effect of different initial dye concentration, adsorbent dosage, contact time, pH, and particle size on dye adsorption. Results show that different parameters can affect the removal rate and adsorption capacity of adsorbent in a different way. The adsorption of dye from aqueous solution onto adsorbent was evaluated using Fourier transform infrared spectroscopy (FTIR) to investigate the functional groups of adsorbent before and after the adsorption process, and it found that the functional group would affect the effectiveness or removal rate and adsorption capacity of adsorbents. The present study indicates that 99.82% of PR with an adsorption capacity of 1.05 mg/g can be removed by 5-gram ambarella peels. While coconut shells had removed 75.78% of RBBR with an adsorption capacity of 7.96 mg/g for 21 hours. The results proved that these agricultural waste were promising materials as an alternative adsorbent for the removal of dye from aqueous solution.

Remazol Brilliant Violet 5R

The potential of agricultural waste materials for removing synthetic dye, Remazol Brilliant Blue R (RBBR) and Remazol Brilliant Violet 5R (RBV5) from aqueous solution were investigated. Water pollution is one of the major environmental issues; dyes have contributed enormous damage to water bodies and greatly impact human health due to high toxicity and carcinogenic by nature. Agricultural wastes are sustainable adsorbents and generally low cost, which has the potential to replace traditional activated carbon. Therefore, this study investigated the removal of RBBR and RBV5 dye from the aqueous solution by adding adsorbent through adsorption. Stink bean pod (Parkia speciosa) was selected as the main adsorbent of this study. The experiment was carried out to study the effect of different initial dye concentration, adsorbent dosage, contact time, and pH level of dye solution. The results have shown that different parameters can affect the removal rate and adsorption capacity of adsorbents in different ways. The adsorption of dye from aqueous solution onto adsorbent was assessed using Fourier Transform Infrared Spectroscopy (FTIR) to determine the functional groups of adsorbent before and after the adsorption process. The FTIR results show that the functional group would affect the removal rate and adsorption capacity of adsorbents. The present study indicates that 83.35% of RBBR with the adsorption capacity of 1.23 mg/g was removed by a 3 g stink bean pod. In comparison, 80.07% of RBV5 with the adsorption capacity of 1.22 mg/g was removed by a 3 g stink bean pod. Design-Expert software was used to generate the equation, which represents the behavior for the adsorption of RBBR and RBV5 dye. The results proved that stink bean pod was promising material as an alternative adsorbent for the removal of dye from aqueous solution.

Laccase Mediator System

The spore laccase of Bacillus amyloliquefaciens LS01 was evaluated for its ability in decolorization of different synthetic dyes. The decolorization process was not efficient by the laccase alone. The addition of mediators could remarkably improve the efficiency of dye decolorization. Remazol Brilliant Blue R and reactive black 5 were resistant to decolorization for most mediators. Acetosyringone was proved to be the best mediator for the spore laccase, and a decolorization of 63−82% was achieved for all the tested dyes in the presence of acetosyringone. The results indicate that the spore laccase-mediator system could be used for the treatment of industrial dye effluents.

Abstract In the present study, pectin-alginate-titania (PAT) composites were synthesized and the adsorptive removal behavior of methylene blue (MB) from aqueous solution, as a model of synthetic organic effluents, onto the prepared PAT composites were investigated by monitoring the effect of contact time, initial MB concentration, and temperature. The adsorption isotherm data were fitted well with the Freundlich isotherm model, suggesting the surface heterogeneity of the PAT composites and that the MB adsorption occurred on the active sites on multilayer surface of the composites. The adsorption kinetics of MB was demonstrated to be pseudo-second order, governed by two intraparticle diffusion rates, and the adsorption process was exothermic, spontaneous, and more disorder. The Langmuir isotherm model suggested that the maximum adsorption capacity of MB on the PAT composites was in the range of 435–637 mg g–1. In general, it increased with the TiO2 NPs content in the PAT composites, due most likely to the increase in surface area exposing more functional groups of the pectin and alginate to interact with the synthetic dye. The adsorptive removal of MB by the PAT composites was found to be more efficient compared with many other reported adsorbents, such as graphene oxide hybrids, pectin microspheres, magnetite-silica-pectin composites, clay-based materials, chemically treated minerals, and agricultural waste. The present study therefore demonstrated for the first time that PAT composites are not only promising to be utilized as an adsorbent in wastewater treatment, but also provide an insight into the adsorption mechanism of the synthetic dyes onto the biopolymers-titania composites.
