摘　　要：文章采用标准加入ICP_OES法测定高盐度卤水中Li、Sr和B,该方法可以避免因大量存在的碱金属离子和其他离子给Li、Sr和B测定带来的影响。各元素加标回收率在90.44%-99.90%之间,相对标准偏差（RSD）〈2%,分析结果准确度高,精密度好,可以准确测定高盐度卤水中Li、Sr和B的含量。A method was developed to determine Li, Sr and B in high salinity brine by ICP-OES with standard addi- tion, which avoids the influences of the large number of alkali metal irons in brine. The recoveries of standard addition for all elements were between 90.44 % and 99.90 % in this method, and the relative standard deviations were less than 2 % in the accuracy test. The determination results show that the method can be applied to deter- mination of Li, Sr and 13 in high salinity brine with high accuracy and great precision.
