Abstract:A new schiff base (salicylaldehydeadenine schiff base, SASB) has been synthesized by the condensation reaction between salicylaldehyde and adenine. And its structure has been identified. With schiff base as color reagents, a new spectrophotometric method for the determination of trace Cu2+ has been established after the conditions of the reaction between SASB and Cu2+ was optimized. The linear range and apparent molar absorptivity at 400nm was 005060 μg/mL and 768×104 L·mol1·cm1, respectively. The method, which was free from the interference of much common ions, could be used for the determination of copper in the presence of 75 times of Al3+ and 25 times of Fe3+ after 2 mL of 100 g/L NH4F was added as screening agent. The results for the determination of trace copper in aluminium alloys obtained by this method with the standard deviation of less than 25% was in agreement with that obtained by AAS.
