Abstract:
Objective To establish an ICP-AES method for determination of the content of Zn in Shenningsan Capsules. Methods The sample was digested with HNO3-HClO4, and determined by the ICP-AES method. The determined wavelength was at 213.8 nm, the electric current of the light was set at 10.0 mA, the slit-width was 0.5 nm, the flow rate of acetylerce was 2.0 L/min and the flow rate of air was 9.4 L/min, the hight of burning was 7.5 mm. Results The ion concentration of Zn had the good linear range of 0.2～1.6 ?g/mL, Y=0.054X+0.001 1 (r2=0.999 3). The average recovery of the content of Zn in Shenningsan Capsules was 99.56% with RSD of 2.00%. The content of Zn in Shenningsan Capsules was 68.6 ?g/g. Conclusion The method is simple and reliable. It can be used effectively for the quality control of Shenningsan Capsules.
