摘　　要：用火焰原子吸收和发射光谱测定了盐湖卤水中锂、钠、钙、镁的含量,考察了酸度对测定结果的影响及各离子相互之间的干扰,并对上述两种方法的优缺点分别进行了探讨。各方法的灵敏度在0.04mL/μg^0.66mL/μg之间;各离子的加标回收率介于99.8%~107.2%,各测定方法的RSD均小于3%。With the flame atomic absorption and flame emission spectrum method, we determined the Li^＋, Na^＋, Ca^2＋,Mg^2＋ content of salt lake brine, its working condition and the influence of acid to the results were also discussed. The sensitivities were in the range of 0.04mL/μg - 0. 66mL/μg,the relative standard deviation of results were under 3% and the recoveries were in the range of 99.8% - 107.2%. The results of determination were satisfied.
