| 摘 要： | 聚合氯化铝(PAC)是一种水处理混凝剂,可为液态(PAC-L),也可浓缩成固体(PAC-S)、PAC-L在水中稀释时铝的形态的变化已用~(27)Al核磁共振法(NMR)进行了研究。本工作试图用~(27)Al NMR法对PAC-S及其在水中溶解稀释物中铝的形态进行研究,以探讨固化对PAC及其在水中铝的形态的影响。

| Abstract: | Aluminum speciation of solid polymeric aluminum chloride (PAG-S) was determined by solid state (27)Al NMR. It was found that the aluminum speciation in PAC-S is influenced by the ratio of OH/A1. When the ratio changes from 1.0 to 2.4, the NMR spectrum of PAC-S varies from that similar to A1C13.6H2O(S) to that similar to Al(OH)3(S). The aluminum speciation in PAC-S aqueous solutions was also determined. The effect of solidification on PAC speciation was discussed. |
