| Abstract: | Through the successively determines of tungsten molybdenum in geochemical exploration sample by catalytic polarography method. In the test, studies main influence factors, such as the coexistence of measurement process interfere ionic remove, the amount of indicator, the influence of acidity, base solution components. And selects the best experimental conditions, determines the linear relationship range of tungsten molybdenum mass concentration and electric current. The test of recovery rate, precision, detection limit, can meet the requirements of geochemical prospecting. The determination results are verifieated by GBW, the results agree with the standard value. |
