Abstract
Objective To establish a method for the determination of trace palladium(Pd)in fosaprepitant and to verify the effect of the Pd-removing process. Methods The microwave digesting method was adopted to process the sample,the Pd residual amount in fos-aprepitant was detected by the graphite furnace atomic absorption spectrometry(AAS) method. Results The mass concentration of Pd within the concentration range of 5-50 μg/L showed the good linear relation with the absorbance( r=0. 999 9). The limit of detection (LOD) was 1. 68 μg/L,the minimal detectable concentration in the sample was 0. 22 μg/g and the average recovery rate was 100. 82% ,RSD=3. 34%( n=9). Conclusion Adopting this method is sensitive,accurate and reliable for detecting the Pd residual amount in fosaprepitant and provides the basis for the quality control of this drug.关键词
