| Abstract: | Copper and nickel were determinated simultaneously in aluminium alloy when Cd2 was used as internal standard ion and NH3-NH4Cl(pH=10) as buffer solution with the method of AC oscillopolarographic internal standard working curve. This method was a new attempt and was of the characteristics of simplicity, accuracy and little interference. The relative standard deviations on determination of copper and nickel were 1.60% and 1 .65%, respectively. |
