摘　　要：建立了一种快速测定油田水中Ba2+、Sr2+含量的新方法,优化了仪器的工作参数。实验结果表明:当Ba2+和Sr2+浓度在1.0—100.0mg/L的范围内,谱线强度I与浓度C之间表现出良好的线性关系,Ba2+、Sr2+的检出限分别为0.10、0.07mg/L,Ba2+的回收率在100.3%—103.0%之间,Sr2+的回收率在95.1%—104.9%之间。本法操作简单,快速,具有良好的精密度和准确度。A new method for the determination of the contents of barium and strontium in oil field brine was established.The instrument parameters were optimized.The good linear relationship was obtained between the line intensity and the concentration in the range of 1.0—100.0mg/L.The detection limits of barium and strontium were 0.10mg/L and 0.07mg/L,respectively.The recoveries were respectively 100.3%—103.0% and 95.1%—104.9% for barium and strontium.This method is simple and rapid with high precision and accuracy.
