Adsorption technique is one of the most technologies being used for treatment of polluted water, but seeking for the low cost adsorbent is the objective of this study. Hexavalent chromium is a known carcinogen. It is generated by metal plating industries, galvanizing industries, mining operations and tanneries. An attempt for naturally available low cost effective adsorbent was made by utilizing Laterite soil, Black cotton soil and Shahapur sand. Kinetics of adsorption was found to follow first order reaction and the adsorption rate of Cr(VI) are 7.37mg/g, 6.41mg/g and 5.12mg/g by Laterite soil, Black cotton soil and Shahapur sand respectively. Adsorption behavior was found to follow Freundlich, Langmuir and Temkin isotherms. For Column tracer experiment the values of Freundlich coefficient KF, Freundlich Isotherm constant 1/n, Distribution coefficient KFd and Retardation factor R for Laterite soil are 1.210, 0.931, 1.032, 2.070 and for Black cotton soil are 1.10, 0.966, 1.192, 2.560 and for Shahapur sand are 0.890, 1.10, 2.522 respectively. The result of the Column Experiment follows Freundlich Isotherm.
