The need to develop a new effective and efficient adsorbent for pollutant removal is insatiable. Tiger-nut activated carbon-zeolite composite (STC) was prepared using sol-gel method by mixing zeolite A and prepared steam activated carbon from tigernut using thermal method for removal of Cr (VI), Pb (II) and Cd (II) from aqueous solution. The material was characterized by Fourier transform infrared (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and Brunauer–Emmette–Teller (BET) respectively. Characteristic vibrational frequency surface area methods. The surface areas and average sizes of the spherically rode-like embedded nanomaterial were 62.20 m2 /g and 41.11 nm. The effect of initial concentration, adsorbent dosage, contact time, pH and temperature on the adsorption capacity were experimentally determined. In adsorption isotherm and kinetics: Langmuir, Freundlich, Temkin, Pseudofirst order, Pseudo-second order and thermodynamic were applied to estimate the adsorption capacity of the adsorbent. From the results obtained, tigernut-zeolite composite showed maximum adsorption of 129.870, 263.158 and 126.582 mg/g for Chromium, Lead and Cadmium respectively.
