| Abstract: | A spectrophotometric method for the determination of bismuth in the electrolytic solution of copper with thiourea after separation concentration by a column filled with fibre of high molecular amine has been developed. The detection limit of the method for bismuth is 0 00038mg/L and its precision is 3 24%(RSD) The method is rapid It has been used in the quality control of the electrolyte in the factory with great success |
