| Abstract: | Effect of five Amino acids on the curves of ion exchange ratio E(%)-pH of interaction between Pb(Ⅱ) and suspended particles in the yellow river was studied.The results showed that:(1)The capacity of five amino acids(2μmol·L -1 ) in enhancing the ion exchange ratio is ranked as:histidine>prdine>alanine>aspartic acid>lysine;(2)As compared to the control experiment,the “S-shaped”curve of amino acids moves to the direction of lower pH value by about 0.4 to 1.3 unit,and the order is ranked as:histidine>aspartic acid>alanine>lysine>proline;(3)The ion exchange ratio enhancing as the concentration of proline.alanine.aspartic acid and cystine rise. |
