Photoelectron spectroscopy using AlK α (h ν =1486.3 eV) has been applied to study the sorption of Cs+ , Sr2+ , Ba2+ , Zn2+ and Co2+ on magnesite kaolinite, smectite and chlorite. From the observed intensities of photoelectron peaks it was determined that in magnesite the sorption affinity of the above ions follow the order: Ba2+ > Co2+ ≅Sr2+ ≅Zn2+ > Cs+ . The order for the sorption of Ba2+ and Cs+ are also determined as chlorite > magnesite > smectite > kaolinite and smectite > chlorite ≅ kaolinite > magnesite, respectively.
