【摘要】：建立电感耦合等离子体发射光谱法同时测定奥贝胆酸中硼和钯含量的方法。奥贝胆酸样品经过微波消解处理后,采用电感耦合等离子体发射光谱法测定。通过实验确定硼的分析谱线为249.77 nm,钯的分析谱线为340.46 nm。方法学验证的结果表明,测定奥贝胆酸中硼和钯的检出限分别为0.02 mg/kg和0.09 mg/kg,线性良好,相关系数分别为0.999 9和0.999 8,RSD分别为0.68%和0.52%,加标回收率分别为100.7%~110.6%和96.7%~110.6%。该方法简化样品的前处理过程,具有快速、准确、灵敏度高及两种元素可同时测定的优点,可用于奥贝胆酸样品中残留硼和钯的测定。
[Abstract]:A method for simultaneous determination of boron and palladium in Obercholic acid by inductively coupled plasma emission spectrometry (ICP-AES) was established.After microwave digestion, the samples were determined by inductively coupled plasma emission spectrometry (ICP-AES).The analytical lines of boron and palladium are 249.77 nm and 340.46 nm respectively.The results of methodology verification showed that the detection limits of boron and palladium in Obercholic acid were 0.02 mg/kg and 0.09 mg / kg, respectively, and the linearity was good. The correlation coefficients were 0.999 9 and 0.999 8 mg/kg, respectively. The recoveries were 100.7 卤110.6% and 96.7%, respectively.The results showed that the detection limits of boron and palladium in Obercholic acid were 0. 02 mg/kg and 0. 09 mg / kg respectively, and the correlation coefficients were 0. 68% and 0. 52% respectively.The method has the advantages of fast, accurate, high sensitivity and simultaneous determination of two elements. It can be used for the determination of residual boron and palladium in Obercholic acid samples.
