锰,人体必需金属元素之一。人体大多通过饮水获取锰。但过量的锰摄入会危害人体健康。在国内,饮水中锰检测并未太过重视。判断锰超标的生活常识方法,主要是闻与看,即有无金属味与水色变化。火焰原子吸收法、离子色谱法是常见的饮水锰测定法,而火焰原子吸收法在锰含量测定上更具准确性,本文主要对比无火焰与火焰原子吸收法下的饮水锰检测结果做分析,希望提供试验性经验参考。实验材料与办法试剂与仪器仪器有原子吸收光谱仪、超纯水机。硝酸镁,分析纯;超纯
Manganese, one of the essential metal elements of the human body. The human body mostly gets manganese through drinking water. However, excessive intake of manganese can endanger human health. In China, manganese in drinking water has not been given too much attention. Judgment of manganese standard method of living common sense, mainly smell and see, that is, whether the metallic taste and color change. Flame atomic absorption spectrometry, ion chromatography is a common method for the determination of manganese in drinking water, and flame atomic absorption spectrometry in the determination of manganese content more accurate, the main comparison of non-flame and flame atomic absorption spectrometry analysis of drinking water manganese, Hope to provide experimental experience for reference. Experimental materials and methods Reagents and instruments There are atomic absorption spectrometer, ultra-pure water machine. Magnesium nitrate, analytical grade; ultrapure
