英文摘要

In the present study a method for determination of BrO3- and Br- using ion chromatograghy coupling with inductively coupled plasma mass spectrometry (IC ICP MS) was developed BrO3- and Br- were separated on a Hamilton PRP X 100(150X 4 1 mm 10 mu m)column guarding with a On guard II RP(4 X 50 mm) column with 10 mmol L-1 NH4NO3 eluent solution at 2 mL By using 200 mu L sample loop, the detection limits for BrO3- and Br- were 0 35 and 0 36 mu g L-1 respectively BrO3- had good linearity in the range 4 8 160 0 ng L-1 The standard solution linear equation was y=250 31x-45 43 and R-2=0 999 9 Br- had good linearity in the range 4 2-140 0 ng L-1 The standard solution linear equation was y=186 84x-127 10 and R-2=0 999 4 Recoveries of spiked samples were 98 9% 109 5% and 97 4% 106 1% respectively The samples included various kinds of Chinese patent drugs waters and beverages Among them 14 bottled drinking waters and 2 kinds of tap waters were found containing BrO3- while other samples were under BrO3- detection limit Br- was detected in all samples
