| Abstract: | The geochemical exploration sample is melted with hydrochloric acid nitrate sulfur（8∶2 V/V） and extracted with alkali solution.In sulfuric acid-potassium chlorate-diphenyl glycollic acid-diphenyl guanidine system,tungsten and molybdenum are determined by catalytic polarography.This method is rapid,simple and accurate.It improves the low efficiency and high blank of alkali fusion method.This method applicables to the analysis for tungsten and molybdenum in geochemical exploration samples.It has been widely used in analysis of large quantities samples detection and obtained good effect. |
