Arsenic adsorption onto iron oxide-coated cement (IOCC): Regression analysis of equilibrium data with several isotherm models and their optimization



Arsenic adsorption onto iron oxide-coated cement (IOCC): Regression analysis of equilibrium data with several isotherm models and their optimization



Chemical Engineering Journal 122(1-2): 93-106



The present work examines the equilibrium sorption of arsenic (III and V) from aqueous environment onto iron oxide-coated cement (IOCC) at 288, 298 and 308 K, and determines the equilibrium sorption isotherms. The equilibrium for both As(III) and As(V) was achieved in 2 h. The experimental isotherm data were analysed using Langmuir, Freundlich, Dubinin-Radushkevich (D-R), Toth and Temkin isotherm equations.
