摘要: Abstract The authors reported that the relative bonding strength between ligand of soil colloid surface and cations could be obtained easily by measurement MCSA, MCSA corresponded to constant Langmuir's adsorption isotherm equation. with respect kaolinitic clay at pH 6 was, Cr3+>Fe3+, Al3+>Ga8+>Cu8+>Pb2+>Y3+, La3+>Mn2+>Ni2+, Co2+> Zn2+>Sr2+, Mg2+>NH4+, K+, humus coating, Y3+, La3+>Pb2+>Cu2+, other orders were same. solubility in aqueous dispersion system was calculated from values MCSAs, considered as follows, La3+, Cu3+, Pb3+, Mn2+, Ni2+, CO2+: concentration solution geochemical mobility may regulated specific reaction, Zn2+, Mg2+, Sr2+, NH4+: non-specific but neutral alkaline condition, Zn2+ an...
