摘要
根据原子荧光法测定水质中汞含量的标准方法,在10℃、20℃、30℃三个不同的室温条件下,测试标准系列溶液并绘制三组校准曲线,相关系数r分别为0.999 80、0.999 25、0.999 89,均具有较好的线性相关性。在三个不同室温条件下测试空白样品,计算不同温度下的仪器检出限分别为0.02μg/L、0.01μg/L、0.01μg/L,符合仪器检出限要求。同时在三个不同室温条件下测试汞水质标样,结果表明10℃、20℃条件下,满足汞水质标样的质控要求;但是30℃条件下测试时,部分测试结果超出了质控范围,不能满足准确度要求。
According to the standard method of atomic fluorescence for determination of arsenic in the water,three sets of calibration curves were given at three different temperatures 10℃、20℃、30℃,and the linear correlation coefficients were 0.999 80、0.999 25、0.999 89.Three blank samples were tested at three different temperatures,and the detection limits were 0.02μg/L、0.01μg/L、0.01μg/L,which met the requirements.Three standard samples were tested at three different temperatures,the test results met the quality control requirements at 10℃、20℃,but some of the test results did not meet the quality control requirements and accuracy requirements at 30℃.
