英文摘要	A new procedure for the direct determination of total arsenic in high salinity and CaCl2 type groundwater has been developed. In order to remove the polyatomic interferences (40)Ar(35C)l(+), (CaCl+)-Ca-40-Cl-35, K-39(36) Ar+ arising from the direct analysis of high salinity and CaCl2 type groundwater, As-75(+), the mass for general detection, was effectively changed to (AsO+)-As-75-O-16 which could be detected at m/z 91 by reaction with oxygen in a Dynamic Reaction Cell (DRC). The DRC parameters were optimized, the background equivalent concentration (BEC) was minimum when O-2 gas flow rate was 0.1 mL/min and the rejection parameter q (RPq) of DRC was 0.55. The signal intensity of (AsO+)-As-75-O-16 was improved 4-fold by addition of 3% methanol into sample solution. The accuracy was verified by the analysis of certified reference materials of sea-water (CASS-5, NASS-4). Detection limits of 0.011 mu g/L and the relative standard deviation of 1.8% were obtained.
