Cisapride in the tablet was determined indirectly by atomic absorption spectrometry(AAS).After the sample was treated by oxygen flask combustion method,excessive silver nitrate was added to generate insoluble silver chloride precipitate with chloride,and the content of remaining Ag+ in the supernatant was determined by AAS after centrifugal separation,and then the content of cisapride tablet was calculated indirectly.Under the optimum determination conditions,the linear range of this method was 0~3.0 mg/L,and the recovery was 97.5%~103.8%.This method has high accuracy and low detection limit,which is suitable for the determination of cisapride in the cisapride tablet.
