摘　　要：本文在以前工作的基础上［６］对铬鞣液和铬废液中铬含量的测定进行了进一步的研究，选用各种氧化剂进行试验，最后选用过硫酸铵将Ｃｒ３＋氧比成Ｃｒ６＋，在低压过渡金属离子色谱仪上进行流动注射分析，从而测得铬含量。通过精密度试验、回收率试验以及与常规分析方法进行对比，验证了此方法的可行性并获得了满意的结果。In this paper the method of determination of the chromium content of chrome liquor and waste chrome liquor was further studied. First using persulfate as oxidizing agent to oxidize Cr3+ to Cr6+, then according to the mechanism that the concentration of colorful substance percents linear relation with its light-absorption degree, the content of chrome was determined by flow-injection method in low-pressure transitive metal ion chromatograph The results of precision test, recovery test and control experiments with conventional method had proved the method is feasible
