采用氢化物发生-原子荧光光谱法测定驱蚊水中的砷(A s)和汞(Hg)。在0—50.0μg/L范围内砷和汞的浓度与荧光强度呈线性关系,相关系数均为0.9993,加标回收率分别达到99.76%—103.46%和90.10%—100.10%,砷、汞测定结果的RSD分别小于3.9%和6.6%;同时指出了测定时应注意的事项。 Determination of arsenic (A s) and mercury (Hg) in insect repellent water by hydride generation - atomic fluorescence spectrometry. The concentration of arsenic and mercury in the range of 0-50.0 μg / L showed a linear relationship with the fluorescence intensity, the correlation coefficient was 0.9993, the recoveries were 99.76% -103.46% and 90.10% -100.10%, respectively. The results of determination of arsenic and mercury RSD were less than 3.9% and 6.6%, respectively; at the same time pointed out that the measurement should pay attention to matters.
