Abstract:The Na2EDTA complexometric titration method for the determination of bismuth content in copper smelting dust was studied. The interfering elements in the determination system were studied experimentally. The determination conditions of the method were discussed. The relative standard deviation of the method is 0.40% ~ 0.67%, and the recovery of the sample is 99.95% ~ 100.20%. The method has high precision and accuracy. It is suitable for the determination of bismuth content in copper smelting dust from 5.00% to 16.00%.
