| 摘 要： | 本文研究了黄原酸盐的一种应用。将滤纸与氢氧化钾和二硫化碳反应，制成黄原酸滤纸（滤纸形态不变）。然后让水样通过，水中的铜离子被其黄原酸螯合生成黄色的纤维素黄原酸铜，用纸上双波长吸光度差值法测定吸光度。该法选择性好，检出浓度可达０．２μｇ／Ｌ，相对标准偏差小于４％。

| Abstract: | Xanthated filter paper was prepared by reaction of filter paper with potassium hydroxide and carbon disulphide.Then,let water sample passing through the xanthated filter paper to convert copper ion into copper xanthate by chelation with the xanthated filter paper.The amount of copper was determined by measuring the absorbance of the copper xanthated filter paper using dual-wavelength method (400nm and 700nm) |
