摘　　要：铬皮粉是定量分析单宁(鞣质)含量所必需的化学试剂,大部分是用于植物鞣料、栲胶产品以及单宁酸产品单宁含量的分析检测。通过近10年从事栲胶产品分析检验的实践,发现目前国产铬皮粉试剂在使用过程中出现的质量问题,包括单宁吸附能力弱、灰分偏重等。The chrome-tanned hide powder is an important chemical reagent for determination of tannin （tannic） content.

It was indicated that the main drawbacks of the present chrometanned hide powder reagent of China were the weak tannin absorption ability, the heavy residual and so on. So the quality of the present chrome-tanned hide powder should be improved.
