摘要

Salbutamol sulfate was coordinated with Cu2+ when pH was 10, and the characteristic absorption peak of the complex was generated at 334 nm. The absorption intensity of the complex was in linear relation with the concentration of salbutamol sulfate. The regression equation was A=0.011 ρsalbutamol sulfate-0.123 0, correlation coefficient r=0.999 5, and the detection limit was 4.6 μg/ml. It was used for the determination of salbutamol sulfate samples successfully. The recovery rate was 100.5%-103.0%, and the RSD was 1.5%.
