摘　　要：采用络合吸附色层法从化学纯的 MnCl_2中去除铁、铜、钴、镍和铅等重金属杂质,以制备荧光纯的 MnCl_2。研究结果表明,将 MnCl_2的溶液通过由络合剂和活性炭组成的色层柱,可将 MnCl_2溶液中的上述杂质提纯到 ppm 数量级;Fe<0.7、Cu<0.8、Co<0.4、Ni<0.4、Pb<0.2。提供了一种设备简单、效率高、质量好的提纯 MnCl_2的方法。A method of chromatographic adsorptionaccompanied with complex-formation was deve-loped and applied for purifying manganese chlo-ride.This method provides a means to removethe following heavy metal impurities to an extent of ppm level:Fe 0.7,Co 0.4,Cu0.8,Ni 0.4 and Pb 0.2.The efficiency of sever-al complexing agents and the optimum processingconditions have been studied.By this methodhigh-purity manganese chloridd can be obtainedefficiently and economically.
