摘要：

In this study, low-cost olive pomace, which is a waste of olive mill, was chemically modified using different acids, characterized, and utilized for the removal of Ce(III) from aqueous solutions. Non-treated olive pomace was used to investigate the effect of chemical modification on cerium(III) removal. BET, SEM, FT-IR, DTA-TG and elemental analysis were realized. The effects of parameters such as solution pH, contact time, initial Ce(III) concentration and temperature on the biosorption were studied. The composition and chemical states of biosorbents was examined after the biosorption of Ce(III) by XPS. Sorption isotherm models, thermodynamic and kinetic parameters were studied.
