| Abstract: | Using 0.025% NH_3·H_2O as medium,the trace iodine and bromine of underground water were determined simutanteously by ICP-MS. The instrumental conditions and the mediums were studied. The method was applied to the determination of underground water. The detection limit of ~(79)Br is 0.02μg/L,and the detection limit of ~(127)I is 0.4μg/L. The recoveries of standard addition are 94.0%-102.4%. |
