农村饮用水水源条件复杂,70%农村人口饮用水未经处理,其卫生状况不容乐观,抓好水质检测是制定改水措施的前提条件。生活饮用水中铁锰砷为必测项目,铁主要用分光光度法、原子吸收法测定;锰主要用原子吸收法测定;砷主要用原子荧光法测定,上述方法都存在耗时、耗试剂、线性范围窄?
Rural drinking water source conditions are complex, 70% of the rural population drinking water without treatment, its health status is not optimistic, do a good job of water quality testing is to develop water purification measures prerequisite. Iron, manganese and arsenic in drinking water are the necessary test items. Iron is mainly determined by spectrophotometry and atomic absorption spectrometry. Manganese is mainly determined by atomic absorption spectrometry. Arsenic is mainly determined by atomic fluorescence spectrometry. Narrow range?
