Streaming current detection for determination of metal complexation capacities of aquatic humic substances

Cu(II) complexation capacities (CuCC) of aquatic organic matter isolated by the XAD-method were determined by means of streaming current detection. The CuCC values of humic like substances isolated from landfill leachates (0.5-1.4 μmol Cu(II)/mg DOC) ware within the range of those determined by differential pulse polarography (0.5-2,3 μmol Cu(II)/mg DOC)
