摘要
采用高效富集技术,以火焰原子吸收法测定清洁水中痕量铜、铅、锌、镉,满足日常分析要求。火焰原子吸收法测定重金属具有快速、准确、干扰少的优点。但因其灵敏度不够无法直接测定清洁水中痕量元素。将高效富集技术,引用火焰法可以测定清洁水中痕量重金属,此法操作简便,易于掌握,免去萃取富集的繁琐操作,避免使用有毒有害有机溶剂,克服无火焰原子吸收法灵敏度差的缺点,减少操作沾污,提高测量准确度。是一种可靠的分析方法。
It adopts efficient enrichment technology-flame atom absorb to determine trace Cu, Pb, Zn, Cd in cleaning water to satisfy daily request for analysis. This way has many advantages such as high speed, accuracy and few hampers. But it cannot determine directly trace element in the cleaning water for not enough sensitivity. The technology can determine trace heavy metal in a way of flame. It is a reliable analysis method with the characteristics of easy-operation, avoiding poisonous solvent, good-sensitivity, less-pollution and more accurate measuring.
