Pure Al(13) solutions at various concentrations were prepared by using the SO(4)/Ba separation method and characterized by using (27)Al-NMR, IR, PCS, AFM and Ferron assay-The mechanism of humic acid removal by coagulation with Al(13), lab-made PACl and industry PACI was compared. Special attention has been paid to the aspects of different coagulation species. The influence of pH and dose was discussed . respectively from the change of zeta potential, residue turbidity, and UV(254). The results show that the Al(13) the dominant and important species in the coagulation process deciding the charge-neutralization ability.
