| Abstract: | The content of polyethylene glycol （PEG） in electroplate solution is determined by ultraviolet spectrophotometry. The result shows that Sn^2＋ in electroplate solution interferes the data of mensuration, and after Sn^2 ＋ is shielded by oxidation, the content of PEG in electroplate solution can be confirmed. The effect is good in the application of corporation. This method of determination is simple and stable in operation and high accuracy can be obtained. It is suitable for popularizing in use. |
