Development of indusrialization and urbanization not only increase economic growth but also contribute to the environmental degradation, especially contamination of heavy metals in water. In other side, there are many geological materials have capability to immobilize heavy metals. Therefore, the objective of this research is to know the maximum capacity of natural zeolite from Trembono area, Gunung Kidul regency to immobilize copper (Cu2+) from water and to understand their mechanism. This experiment was carry out by a batch test. The result showed that the maximum capacity of zeolite to immobilize Cu (qmax) is 63,69 mmolCu/kg Zeolite according to Langmuir adsorption equilibrium model. In addition, the capability to immobilize Cu will increases due to decreasing the grain size. The result of this research can be used as an alternative for waste water treatment, especially Cu.

Day By Day

With the development of industrialization and human activities, discharge of waste water containing heavy metals in the environment is increasing day by day. It causes serious threats to the human civilization and the flora and fauna in this earth. Conducting polymers like polypyrrole and polyaniline can be used for treating wastewater due to their inherent ion absorption properties. This article has been focused on the development of polypyrrole coated bio-composites and their potential about the removal of heavy metals from industrial wastewater. Adsorption process can be successfully employed to remove heavy metals from the wastewater by the treatment of water with polypyrrole-coated composites. It was reported in literature that the polypyrrole and polyaniline-coated adsorbents had good adsorption capacities for Mg, Fe, Cu, Cd, Pb, Zn, and Ni. Polypyrrole-coated saw dust, rice husk, chitin, and cellulosic materials could be able to remove Cr, Fe, Cu, and Zn from wastewater. This method would be a replacement for costly conventional methods of removing heavy metal ions from wastewater. It is expected that this method would be an alternative for waste water treatment which will benefit the industries in future.

Harzadous waste water is the waste that can be harmful to human’s health. One of heavy metals that contains in harzadous waste is cadmium. This research aims to investigate the characteristic of cadmium adsorption, equilibrium time, percentage adsorption, adsorption kinetic, adsorption isotherm and capacity of cadmium adsorption by using duck egg’s shell adsorbent. Duck egg’s shell adsorbent that had been activated at 600 oC were put into cadmium solution and mixed together. Every 10 minutes experimental samples were analyzed using AAS. The results indicated that percentage adsorption increases and the longer equilibrium time will be reached with an increase of adsorbent dosage. The Lagergen first order Models was applied as adsorption kinetics model and the Bangham Models was applied as adsorption isotherms models.

Nanotechnology is one of the most reliable techniques for the remediation of heavy metals. As nanoparticles have a higher surface area to volume, ratio, and high surface energies, so nano-based absorbents are very efficient. Adsorption technique is the most preferred for the remediation of wastewater pollutants. In the current study, a comparative study was done between bio sorbents, nanosorbents and bio nanosorbents. The chapter studies with the synthesis and characterization of the bio sorbents, bionanosorbents, their mechanism of sorption, their synthesis, in addition, application for the remediation of heavy metals from wastewater. The fly ash is an industrial byproduct. Biosorbents have immense applications in the field of bioremediation of heavy metals. Further, their components have also enhanced removal efficiency from the wastewater.

AbstractRecently, mass production of lipid along with heavy metal reduction is gaining momentum due to their cost-effective and greener approach towards waste water treatment. The purpose of this study is to investigate the small scale photo bioreactor treatment of tannery effluent using Chlorella sp. isolated form Yercaud lake, Tamil Nadu, India. The results showed a significant decrease in the heavy metals content in the tannery effluent after the treatment. Maximum reduction of the heavy metal Chromium (Cr) of 10.92 mg L−1 was recorded, followed by Cobalt (Co)-7.37 mg L−1, Nickel (Ni)-9.15 mg L−1, Cadmium (Cd)-8.48 mg L−1, Lead (Pb)-12.54 mg L−1, Zinc (Zn)-11.56 mg L−1 and Copper (Cu)-10.71 mg L−1 at the end of the 20th day of treatment. The microalgae, Chlorella sp. was analyzed for their biosorption ability and the maximum biosorption capacity (qmax) rate against heavy metals was 81.36, 70.53, 82.15, 63.29, 58.92, 83.43, 64.83 µg L−1 for Cr, Pb, Ni, Cd, Co, Zn, and Cu respectively. It matched with the Langmuir and Freundlich kinetics models. The maximum CO2 utilization was found to be 60.50% and maximum concentration of lipid, carbohydrate and protein was found to be 0.95 g L−1, 250 µg mL−1 and 160 µg mL−1, respectively. The presence of various groups such as hydroxyl, alkyl, carbonyl and carboxylic acids was confirmed using Fourier transform infrared analysis. Thus, the isolated microalgae showed good biosorption ability towards the various heavy metal pollutants from tannery waste water.
