| 摘 要： | 建立了电感耦合等离子体质谱法同时测定地下水中B、Br、I的方法。选定φ=2%(体积分数)的稀NH3.H2O介质消除碘的记忆效应。采用干扰较少的10B和79Br同位素。B、Br、I在0~10 000 ng/mL呈良好的线性关系。方法的检出限为10B 0.176 ng/mL,79Br 0.876ng/mL,127I 0.132 ng/mL;精密度(RSD,n=12)为10B 2.86%,79Br 3.36%,127I 2.69%;10B的阶梯加标回收率为94.6%~101.5%,79Br为98.3%~104.9%,127I为96.5%~102.0%。

| Abstract: | 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(φ=2%) 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 ng/mL,0.876 ng/mL 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. |
