| Abstract: | A novel spectrophotometric method for the determination of terbutaline has been developed.The method is based on 2-hydroxy-1,4-naphthoquinone formed from hydroxyl ion and NQS in a 0.20 mol/L NaOH by using terbutaline as catalyzer.In the range of 0.12~8 mg/L,the concentration of terbutaline is linear with the absorbency of 2-hydroxy-1,4-naphthoquinone which maximal absorption wavelength is 452 nm.The equation of linear regression is A= 0.057 92+0.069 52C(mg/L),with a linear regression correlation coefficient of 0.99 77.ε452 is 3.8×104 L/mol-1cm-1.The proposed method has been successfully applied to the determination of terbutaline in tablets of pharmaceutical preparation.The recovery rate is in the rang of 98.5%~101.8%. |
