Method for analyzing ions in dimethyldichlorosilane hydrolysate

The invention provides a method for analyzing ions in dimethyldichlorosilane hydrolysate. The method includes the following steps that a hydrochloric acid solution is added into the dimethyldichlorosilane hydrolysate, metal ions in the hydrolysate are eluted, a water layer is separated through a separating funnel, the contents of a sodium ion, a potassium ion, an iron ion, a calcium ion and the like are detected through plasma emission spectroscopy in the water layer, or a certain amount of pure water is added into the certain dimethyldichlorosilane hydrolysate, heating reflux is carried out for 2 hours at the temperature of 100 DEG C to 140 DEG C, the water layer is separated through the separating funnel, and the content of a chlorine ion is detected with the potentiometric titration method. By means of the method, the void of ion detection of the dimethyldichlorosilane hydrolysate is filled, and the method has remarkable social benefits and economic benefits. 本发明提供种二甲基二氯硅烷水解物中离子的分析方法，包括以下步骤：在的二甲基二氯硅烷水解物中加入
