Adsorption studies of Zinc from Zinc acetate solutions on Clay (Kaolinite) were made under varying conditions of time and pH. Adsorption equilibrium was found to be established within two hours in case of Zinc acetate solution of 50 ppm concentration. Increase in pH was found to have a significant positive effect on the extent of adsorption. Freundlich's and Langmuir's equations, when applied to the isotherm data, obeyed very well.
