Abstract:
AIM To establish a UV spectrophotometry for the determination of arsenic in Jiuji Xingjun Capsules. METHODS Arsenic was transformed into hydrogen arsenide,then silver diethyldithiocarbamate was reduced for colloid silver by hydrogen arsenide,its absorbance was determined at the wavelength of 507 nm. RESULTS The linearity range of curve was 0.5-4.5 ?g?mL -1 ( r =0.999 5, n =7),The average recovery was 100.11 % ( RSD =1.64 T《B》 % , n =15). CONCLUSION This method is rapid and accurate.
