ABSTRACT:

The studies on removal of Vanadium were conducted using Granulated Activated Carbon (GAC) in combination with Chelating agents. Ethylene di-amine Tetra Acetic Acid (EDTA) and Nitrilo Tri Acetic Acid (NTA) at 25oC. The adsorption Efficiency was studied in the pH range of 2-8. The results reveals that Langmuir and Freundlich isotherms are followed during adsorption process with the chelating agents under study. The granulated activated carbon (GAC) loaded with Ethylene di-amine tetra acetic acid (EDTA) shows greater adsorptive capacity as compared to granulated activated carbon (GAC) loaded with the chelating agent, Nitrilo-Tri-acetic acid (NTA).

KEYWORDS:

Pentavalent Vanadium; Langmuir and Freundlich isotherm; Chelating agent; Water pollution; Activated Carbon
