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%.展开更多
