原子吸收分光光度法测定水中微量镉

Determination of Trace Cadmium in Water by Atomic Absorption Spectrophotometry

水是人类生存中不可或缺的资源。水中所含很多微量金属元素也是人体所必需的,但过量的金属元素又是危害人体健康的利剑。因此,在水供应环节中,检测水中超标的微量金属元素对人类生活至关重要。本文采用控制变量的方法,提出了优化石墨炉原子吸收分光光度法检测镉元素的工作参数的具体设想。

Water is an indispensable factor to the survival and development of nature and mankind.Trace metal elements in the water are necessary for the human body,whereas excessive metal elements can hazard human health.Therefore,in the water supply link,the detection of excessive trace metal elements in the water is extremely important for human life.This paper adopts the method of variables controlling,and puts forward a specific assumption of optimizing the working parameters of graphite furnace atomic absorption spectrophotometry to detect cadmium.
