摘要
提出用一种新的方法,使显色剂与铬鞣剂中六价铬反应后再与对甲基苯磺酸络合,然后用异戊醇将六价铬萃取出来,最后用标准加入法对铬鞣剂中六价铬进行定量分析,该方法可以排除铬鞣剂中复杂的背景干扰,测试数据准确,稳定性好。
A method was developed to hold with p-methylbenzene sulfonic acid and to abstract Cr（ VI ） from tanning powder with isoamyl alcohol , and analyse Cr（ VI ） with standard adding method, this method can overcome interference from any side, and the result is accurate, and outstanding stability.
