Abstract: ABSTRACT:OBJECTIVE To develop a method for the determination of 6 hazard elements such as Cr,Cu,As,Cd,Hg and Pb in Spatholobi Caulis .METHODS After the microwave digestion and then 6 hazard elements were determined by ICP-MS at the same time.Based on this,the limit of Cr,Cu,As,Cd,Hg and Pb were assessed with WHO standards.RESULTS The determination results of 6 hazard elements all have a good linear relationship,r ≥0.999 8.The limit of detection was range from 0.001 6~0.022 7 ng∕mL,the average recovery was 70.05%~1 1 7.98%,and RSD were 1.30%~3.69%.Determina-tion results of samples of 6 hazard elements less than the maximum limit value(0.800 0,140.0,0.857 1,0.400 0,0.228 6,1. 429 mg∕kg).CONCLUSION The method is simple,accurate and high sensitive,can be used for the quality control and limit assessment of Spatholobi Caulis .
