Abstract

Using AlCl3 as raw materials, Polyaluminum chloride(PAC)with high Al13 content was prepared by electrolysis with exchanging electrodes. The synthesis mechanism of Al13 in the process of electrolysis was discussed, the effects of electrolysis voltage, the original concentration of Al 3+, the circulation mixing rate of the electrolyte and the exchanging frequency of the electrodes on the synthesis velocity of Al13, ratio of Al13 in total Al(AlT) and the electrolysis time were studied. The optimum conditions are determined: the exchanging frequency of the electrodes is once per minute, the original concentration of Al3+ is 0.5000mol·L-1, the electrolysis voltage is 12V, and the circulation mixing rate of the electrolyte is 0.5L·min-1. Under the optimal conditions, the liquid product with basicity of 82.0% and Al13 polymer accounted for 91.2% of total Al is successfully prepared.

Key words： Al13 polymer; synthesis speed; electroanalysis prepraration; exchanging frequency of the electrodes
