Photoelectron spectroscopy: A tool in sorption studies

Photoelectron spectroscopy using $AlKalpha$ (hv=1486.3 eV) has been applied to study the sorption of $Cs^+$, $Sr^{2+}$, $Ba^{2+}$, $Zn^{2+}$ and $Co^{2+}$ 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:$Ba^{2+}>Co^{2+}cong Sr^{2+}cong Zn^{2+}>Cs^+$. The order for the sorption of $Ba^{2+}$ and $Cs^+$ are also determined as chlorite>magnesite>smectite>kaolinite and smectite>chlorite $cong$ kaolinite>magnesite,respectively.
