用钨丝折成三折钨丝电极作为富集电极和石墨管相匹配进行原子吸收测定,用改进加权形心单纯形优化测定条件,改进加权形心单纯形的推移过程用PB-700计算机自编程序,自动进行,对一次蒸馏水和优级纯KCl中的铜的测定进行研究。
The tungsten wire was folded into three-fold tungsten electrode as the enrichment electrode and the graphite tube to match the atomic absorption spectrometry. The modified centripetal simplex was used to optimize the measuring conditions and to improve the process of the centripetal simplex. Programmed, automatic, the determination of copper in a single distilled water and superior grade pure KCl was studied.
