| Abstract: | A method for the determination of bismuth in tin anode slime using Na2EDTA standard titration solution was studied. Dissolution of tin anode slime, titration acidity, titration temperature, interference of coexisting elements, accuracy and precision of the method were discussed. The method is suitable for the determination of bismuth in tin anode slime with the bismuth concentration of 5%~20% and especially when indium content is more than 0.1%. This method has the advantages of simple operation procedure, wide applicability, good reproducibility and high precision. |
