Environmental Chemistry (Mr. Jitendra Kumar Sahoo)

Water pollution due to the aimless disposal of heavy metals and dyes are generating a rising worldwide environmental concern. For example paper, textile, food, plastics, cosmetic and petroleum industries. These heavy metals and dyes are reported to be toxic, carcinogenic and mutagenic even with a small amount of heavy metals and dyes discharged in to water that affects the aquatic ecosystem and poses a serious hazard to living organisms. Thus the removal of heavy metals and dyes from waste water is necessary and important before colored effluents are discharged in to the environment. Most of these heavy metals and dyes are present in environment which are responsible for causing cancer in human beings and a potential threat to bioaccumulation and unfavorable susceptible issues. Most of these dyes in view of its complex structure, restricted biodegradability, soundness towards light and high dissolvability in watery arrangement.

Till date, techniques like photo-degradation, adsorption, solvent extraction, coagulation, bio-degradation, oxidizing agents are considered to be the center-stage in the removal of toxic materials from the contaminated water systems. Among these, the adsorption is a classical technique due to its simplicity and high level of effectiveness. We are adopting adsorption process to remove these toxic materials using our synthesized nanocomposites.
