In this research, cassava peel (Manihot esculenta) was used to removechromium (VI) from aqueous solution simulating industrial effluents.Batch adsorption operation was used and tests were performed by varyingthe initial concentration of chromium solution (30, 40 and 50 ppm)and temperature (25, 30 and 35 °C), keeping fixed the adsorbent dosage(3.33 g/l), the contact time 40 minutos and pH 2, which was adjusted withsulfuric acid (H2SO4). Data were fitted to four kinetic models: reversiblefirst-order, pseudo second-order, Elovich and intraparticle diffusionmodels. Pseudo second-order model fits best to most experimental data.Tests were also performed using an initial concentration of 50 ppm andcontact time of 120 minutos, varying the adsorbent...
