摘要
利用阳离子交换树脂分离铬(Ⅲ)阳离子配合物,对洗脱剂、树脂(001×7和D001)进行了选择,并对洗脱剂浓度、流量、温度等因素进行考察,最后将分离出来的3种铬(Ⅲ)阳离子配合物进行可见光谱的测定,结果与文献提供的数据相吻合。结果表明,使用D001大孔阳离子交换树脂以及采用0.1,0.5,2 mol/L的高氯酸来洗脱和分离3种铬(Ⅲ)阳离子配合物的效果较好。该研究在制取、提纯无机盐的高纯化合物以及配离子的分离、鉴定方面有一定的参考价值。
In the process of the experiment,the chromium（Ⅲ）cationic complex was separated by using ion exchange method.Different desorbents and resins（001×7 and D001） were selected to exchange chromium（Ⅲ）cationic complexes,and the concentration of desorbent,flow rate,temperature were discussed.Finally,three chromium（Ⅲ）cationic complexes were measured with visible spectrum.Results showed that D001 resin and perchloric acids with the concentration of 0.1,0.5,2 mol/L were the best selection.This study has some reference value in the preparation,purification of high purity inorganic compounds,ion isolation and identification.
