| Abstract: | In the light of the problem existing in the determination of the ZnSO 4 percentage in the spinning bath by potassium ferricyanide, the author try to determine it by EDTA(ethylene diamine tetraacetic acid), and compare the results of the two methods under the same conditions. The results show that EDTA method takes the advantage of high accuracy, low cost, convenient operation, non-poison and harmless etc. |
