One of the most favorable techniques of wastewater treatment has been adsorption. Hence, soil was modified so as to get a promising adsorbent with salient features, including enhanced adsorption efficiency and favorable kinetics. The adsorbent was studied with FTIR (Fourier transform Infrared spectroscopy), SEM (Scanning electron microscope) and EDX (Energy Dispersive X-Ray Analyzer) so as to understand the characteristics of the adsorbent.  It was observed that the adsorption followed Langmuir’s isotherm and pseudo-second order kinetic models. At the optimum pH of 8, the saturation level of adsorption, of 78.5 mg g^-1 of Zn²⁺, was reached within 20 min.
