Iron Adsorption from Textile Industrial Effluent on Activated Carbon Prepared from Tamarind Seeds (Tamarindus indica L.)

Abstract

Water pollution contributes the major environmental pollution in many countries which shows great impact on human life and biodiversity. The important source of water pollution is industrial effluent. General contaminants in effluent water are heavy metals, phenols, dyes, harmful organics, ligands and suspended solids .Treatment of effluent water plays vital role in many industries, the treatment of adsorption proved to be most important well known and economical process. The ability of certain solids of preferentially concentrate specific substance on their surface is the basic principle for adsorption. Water with high content of iron can be very objectionable. In our research work the activated carbon prepared from tamarind seeds was employed to take up selected heavy metal that is iron ions. Tamarind seeds which are an agricultural waste and also waste product in many industries was activated by phosphoric acid treatment, is investigated for the removal of iron ions from textile industrial effluent sample.
