摘　　要：为实现对水环境中汞含量的精准测定,本文选用原子荧光技术作为检测手段进行后续操作。由实验结果可知,待测样品检出浓度为0.0023μg/L,符合国家规定的重金属中汞元素含量标准。该技术在进行汞含量测定时,精密度的相对偏差值为1.6%,而准确度由加标回收实验进行测定后,可得平均加标回收率为98.4%。根据实验结果可以很明显地看出,原子荧光技术对于样品中汞含量的测定精准,可以满足在水环境中对汞含量的检测。In order to achieve the accurate determination of mercury content in water environment, atomic fluorescence technology is selected as the detection method for follow-up operation. According to the experimental results, the detection concentration of the sample is 0.0023μg/L, which meets the national standard of mercury content in heavy metals. The relative deviation of precision is 1.6%, and the average recovery of standard addition is 98.4%. According to the experimental results, it is obvious that the atomic fluorescence technology for the determination of mercury content in the sample is accurate, which can meet the detection of mercury content in the water environment.
