摘要
本文对原子吸收法测定样品中铜的含量进行探究,利用标准曲线法作为定量分析方法,在仪器推荐的浓度范围内,制备含待测元素的对照样品溶液6份,浓度依次递增。用原子吸收分光光度计测量出不同浓度下样品溶液的吸光度,绘制出浓度吸光度标准曲线。探究所测样品吸光度下含铜的浓度。
This paper on the atomic absorption method for the determination of copper content in a sample inquiry, using standard curve method as a quantitative methods, in the concentration range of the instruments featured, containing elements to be measured in the control sample 6, concentration increased in turn. Atomic Absorption Spectrophotometer measures the absorbance of the sample solution at different concentration, draw standard curve of absorbance concentration. Explore the measured sample absorbance with concentration of copper.
