| Abstract: | In the electrolyte with potassium sulfate,make fluosilicic acid and lead to precipitate and be separated from other elements,then settling into a solution which can be titrated with sodium hydroxide standard solution to determine fluosilicic acid content,and be titrated with EDTA standard solution to determine lead content.The precipitation separation-continuous titration method is accurate and rapid,and the accuracy and precision of the method could meet the demand of quality control in production. |
