| Abstract: | The concentrate sample is digested by hydrochloric acid - potassium chlorate, the arseno - antimono - molybdenum blue spectrophotometrie method with amine absorption by zinc reduction iodine liquid for determination of arsenic in tin concentrate is researched. And the reagent effect, coexistence elements interference, separation and masking are tested too. The relative standard deviation of the method is 1.93% -6. 99%, and the recovery of standard addition is 93. 3% - 105.7%, the result is stable, and the reproducibility is good, it can meet the requirements of determination of arsenic in tin concentrate. |
