Determination of Silver in Water by Flame Atomic Absorption Spectrometry

Autor: Masatsugu Kubota, Satoshi Saeki, Teruo Asami

Publikováno v: International Journal of Environmental Analytical Chemistry. 64:185-192

A precise method to determine Ag in natural water using flame atomic absorption spectrometry is described. This method consists of the precipitation of Ag with Fe3+ and Na2S, and the separation of Ag into methylisobutylketone (MIBK) using sodium N,N-
