摘要
对 46个皮革试样浸取液中Cr(Ⅲ )和Cr(Ⅵ )含量的测试进行了研究 ,结果表明 :不同皮革试样浸取液中的Cr含量大小不一 ,且有的还相差较大。用双空白法测定有色皮革试样浸取液中的Cr(Ⅵ )含量 ,有一定的可操作性。
The study on determination of chrome (Ⅲ) and chrome (Ⅵ) contents in these 46 leather sample entractable liquors was done. The results show that there is a wider distrubition range of chrome contents in leather sample extratable liquor. When the total chrome (Ⅲ) contents in leather sample is higher, the chrome (Ⅵ) content is not necessarily higher. Using the double blank method to determine the chrome (Ⅵ) content in colored leather samples extractable liquor has a certain controllability.
