    Abstract:
    The polynuclear Keggin species, Al12AlO4(OH)24(H2O)12(7+) (Al13), was separated and purified from polyaluminum chloride (PAC) by gel column chromatographic method. The purified Al13 was characterized by Al-Ferron timed complexation spectrophotometry method and ZATESIZER 3000HSA tester compared with PAC and ALCl3. Jar tests were performed to test the coagulation efficiency of the three coagulants in treating synthetic or actual water samples. The results showed that Al13 could be obtained by the column chromatographic method and the content of it could reach about 99%. Compared with PAC and AlCl3, Al13 gives the best results for turbidity, humic acid and color removal, and achieves the highest charge-neutralizing ability. Al13 species is a higher positive-charged and wide pH range application, it is much more steady in hydrolyze process and most effective polymeric Al species in water and wastewater treatment.
