摘　　要：采用RA-915+型汞分析仪对海水中的总汞进行了测试。进行了线性关系、检出限、准确度、精密度、回收率等实验。实验结果表明,本方法检出限0.00002mg/L,在0～40000pg范围内线性良好。本方法操作简单,灵敏度高,结果准确。The total mercury in seawater was determined with RA-915^＋ Mercury Analyzer. The experiments on linear correlation, detection limit, accuracy, precision and recovery rate were conducted. The results showed that the detection limit was of 0.000 02mg/L and the technique was in a good linear relation in the range between 0-40 000 pg. The technique is easy to use with high sensitivity and accuracy.
