Abstract

The studies on removal of Hexavalent Chromium were conducted using activated charcoal prepared from Phyllanthus Emblica tree bark (AC-PETB). Chromium (VI) adsorption from an aqueous solution has been studied experimentally using the batch adsorption method. The operating variables studied are pH, initial concentration, temperature, adsorbent dose, contact time. Adsorption isotherm like Langmuir and Freundlich model were studied. To enhance the adsorption capacity of activated carbon, it is loaded with Sodium lauroyl sarcosinate and 2-Acrylamido-2-methylpropane sulfonic acid and compared the adsorption capacity.
