Review of Renewable Biosorbent from Coir Pith Waste for Textile Effluent Treatment

摘要

Biosorption is an innovative technology aimed at the removal of toxic metals from effluent utilizing abundantly available agricultural waste biomaterials. Among several agricultural wastes studied as biosorbents for effluent treatment, coir pith has been of great importance for the removal of diverse type of pollutants from effluent water. As an agricultural waste, coir pith has gained wide attention as effective biosorbents due to the significant adsorption potential for the removal of various aquatic pollutants. Cost-effectiveness, abundant availability and renewability makes them as an economical alternative for water treatment and waste remediation. In this review, the perspective of coir pith based biosorbents for textile effluent treatment from vast literature has been compiled and their adsorption capacities for various types of as available in the literature are presented.
