Abstract

Objective To establish the method for the determination of Pb,As,Cd in blood by Octopole Reaction System Inductively Coupled Plasma Mass Spectrometry(ORS-ICP-MS). Methods The samples were digested by closed-vessel HNO3 dissolution system. The solution was directly analyzed by ORS-ICP-MS for the determination of As、Pb、Cd. Results The detection limits of each element was between 0.13μg/L～0.52μg/L. Standard linear correlation r≥0.999.Standard deviations were below 5%. The RPD of the different methods was below 10%. Standard reference materials were used quality control standards and the analysis results conformed well to the certified values. Conclusion The method was proved to be simple, rapid, accurate and reliable. And it has been applied to the analysis of the sample with satisfactory results.
