| Abstract: | A new type of polymeric aluminum ferric chloride has been prepared with kaolin tailings. Its phyto-chemical and electrochemical properties have been tested. The results show that when pH〈8 ,PAFC has positive electrical property. The structure and electro kinetic properties of polymeric aluminum ferric chloride were tested by Fourier transform infrared spectroscopy. We also studied the relationship between Zeta potential and COD removal efficiency, and explored the flocculation mechanism of PAFC. Finally,we applied it to the actual printing and dyeing wastewater treatment, and achieved satisfactory results. |
