摘要：
The adsorptive collection of the aluminum complex with cupferron is exploited for developing a highly sensitive stripping procedure for trace aluminum. Optimal experimental conditions include the use of 2 x 10(-4)M cupferron in PIPES buffer (pH 7.0), an accumulation potential of -0.40 V and a linear potential scan. With controlled accumulation for 2 min, a detection limit near 30 ng/l. aluminum is obtained. The relative standard deviation (at 5 mug/l.) is 2.9%. Possible interferences are evaluated. The analytical performance compares favourably with that of early adsorptive stripping schemes for aluminum.
