聚羟基氯化铝形态分布的研究

Study on the Speciation of Polymeric Hydroxy Aluminum Chloride

采用Ｆｅｒｏｎ逐时络合比色法研究了聚羟基氯化铝（ＰＡＣ）的形态分布以及陈化和稀释对其分布和转化规律的影响。研究表明，ＰＡＣ的形态分布取决于羟铝比（ｒｎ）、Ａｌ（Ⅲ）总浓度和陈化时间等因素。

Ferron-complexation timed spectrometry was used to study the speciation of polymeric hydroxy aluminum chloride in solution.Eeffects of dilution and aging on aluminum speciation was studied by ferron-complexation timed spectrophotometry.Results showed that aluminum speciation depended on such factors as the OH/Al 3+ ratio,total Al concentration,and time of aging.
