砷是水质卫生化学主要监测毒物,多年监测结果表明,水中砷含量较低[1],砷的检测方法有砷斑法,灵敏度低;银盐法准确度可靠,但操作繁琐,灵敏度低;火焰原子吸收光谱法、石墨炉原子吸收光谱法,无法满足测定需要;原子荧光法具有谱线简单、检出限低、线性范围宽、灵敏度高干扰少、操作
Arsenic is the main indicator of health monitoring of water quality chemicals, monitoring results show that many years of low levels of arsenic in water [1], arsenic detection method with arsenic stain, low sensitivity; silver salt method is reliable, but cumbersome, low sensitivity; flame Atomic absorption spectrometry, graphite furnace atomic absorption spectrometry, can not meet the determination needs; atomic fluorescence spectrometry with simple spectral line, low detection limit, wide linear range, high sensitivity, less interference, the operation
