混凝剂三氯化铁稀溶液的水解及防治

On the Prevention of Hydrolysis of FeCl_3 as a Kind Coaqulant in Dilution

三氯化铁作为一种自来水混凝剂,在稀释过程中极易水解。其水解程度与PH值、温度、溶液浓度、贮存时间等诸多因素有关。实验证明:三氯化铁稀溶液的水解在一定条件下是可以避免的。

FeCl3 is very easy to hydrolyze during the process of diluting as a kind of Coaqulant, the degree of dilution depends on PH value of the solution ,temperature, the cocentration of solution and the length of time of storage. Experiments have proved that the hydrolysis of diluted solution of FeCl3 can be avoided.
