摘　　要：采用电感耦合等离子体原子发射光谱法测定天然卤水中锶的含量。选择波长216.579 nm为锶的分析线,方法的检出限(3S/N)为0.01mg·L^(-1)。方法用于天然卤水样品的分析,测定值与火焰原子吸收光谱法的测定值相符,加标回收率在95.9%～102.0%之间,在5个浓度水平上加入锶标准溶液做精密度试验,测定值的相对标准偏差(n=12)在0.43%～3.3%之间。ICP-AES was applied to the determination of Sr in natural brine. Wavelength of 216. 579 nm was selected as analytical spectral line for the determination. Value of detection limit （3S/N） of 0. 01 mg. L^- 1 was found. The proposed method was applied to the determination of Sr in samples of natural brine, the results obtained was in consistency with those obtained by FAAS. Test for recovery was made by standard addition method, and values of recovery obtained were in the range of 95. 9%- 102. 0%. Precision was tested by addition of standard strontium solution at 5 concentration levels, values of RSD＇s （n=12） found were in the range of 0. 43%-3.30%.
