摘　　要：研究了在实验室条件下利用一次加碱法制备聚合氯化铝的过程中 ,总铝浓度及碱化度对聚合氯化铝中铝聚合形态组成的影响 ,结果表明 :随碱化度的提高 ,低浓 PAC中 Alc含量变化较小 ,而高浓 PAC中 Alc含量呈显著上升趋势 ;同时 ,低浓 PAC中 Alc的含量呈较明显增加 ,而高浓 PAC中 Alb含量则呈缓慢下降趋势 ;无论高浓还是低浓 PAC,其 AlaThe effects of total aluminium concentration and basicity on aluminium species component of polyaluminium chloride (PAC) were studied when polyaluminium chloride was made by instantaneous injection in laboratory.It was shown that with the increase of the basicity,the content of Al c almost didnt change in the lower total aluminium concentration while the content of Alc increased apparently in the higher one.At the same time,with the increase of the basicity,the content of Al b increased apparently in the lower total aluminium concentration while the content of Al b decreased gradually in the higher one.In addition,the contents of Al a in both of PACs of the lower and higher total aluminium concentration decreased distinctly.
