摘要
采用乳状液膜法对皮革试样浸取液进行处理,分离其中的Cr(Ⅵ),而后用双空白法测定分离液的Cr(Ⅵ)含量。同时用KMnO4氧化法分别测定分离前后试液的总铬含量,测试结果表明:乳状液膜法可以高效地分离皮革试样浸取液中的Cr(Ⅵ),分别测定分离前后溶液的总铬含量,即可以计算皮革试样中Cr(Ⅵ)的含量。本方法测试准确,简单易行。
The emulsion membrane was adopted to treat the leather sample extractable liquid, to separate the chrome（ Ⅵ ） in it and then to test chrome （ Ⅵ ） content by the double blank method. At the same time, KMnO4 oxidation is used to respectively test the total chrome contents in preparation before and after separation. The testing results show that the emulsion membrane can separate effectively the chrome （ Ⅵ ） in leather sample extractable liquid. Respectively testing the total chrome contents before and after separation can calculate the chrome （ Ⅵ ） contents in leather sample. This method has some advantages, such as accuracy, simplicity and practice.
