摘要
用纯铝箔和盐酸反应制备出一系列盐基度不同的聚合氯化铝,并利用Ferron逐时络合比色法和27AlNMR法详细考察了其形态分布。混凝实验结果表明,聚合氯化铝盐基度与其混凝性能密切相关。在相同的实验条件下,盐基度越高,聚合氯化铝的混凝效果越好。
In this paper, a series of poly aluminum chloride samples wereprepared by pure aluminum foil and hydrochloric acid with different basicity. The hydrolytic species distribution of the samples were explored by Al-Ferron timed complex colorimetric method and ^27 AlNMR. By contrasting the coagulation performance in the jar tests,it was found that basicity was one of the most important indicators,and the samples with higher basicity had better coagulation performance under the same experimental conditions.
