  cation
Analysis of statistical thermodynamic model for binary protein adsorption equilibria on cation exchange adsorbent
      
Seven pore water samples were analyzed for their anion (Cl-, SO42-, Br-, I-) contents, cation (Na, K, Ca, Mg) contents and trace element (Li, B, Sr, Ba, Rb, Mn) contents.
