摘要

A method for the determination of boron, bromine and iodine in groundwater samples by inductively coupled plasma-mass spectrometry (ICP-MS) was proposed. Weak ammonia solution was selected to eliminate the memory effect from iodine. The isotopes of ¹⁰B and ⁷⁹Br were chosen as determination isotopes for the less interference from coexistent elements. Linearity of boron, bromine and iodine are in 0~10000 ng/mL. The detection limits of the method for ¹⁰B, ⁷⁹Br and ¹²⁷I are 0.176, 0.876 and 0.132 ng/mL, respectively. The recoveries of the method are 94.6% ~ 101.5% for B, 98.3% ~ 104.9% for Br and 96.5% 102.0% for I with precision (RSD, n=12) of 2.86% for B, 3.36% for Br and 2.69% for I.
