Spectrochemical cobalt, molybdenum and copper determinations in plants

Abstract

This paper deals with the spectrochemical determination of some trace elements (Cu, Mo and Co), especially in plant samples. Data are given about the choice of light source and spectral apparatus, as well as detailed remarks concerning the optical arrangement.

In the concentrating pretreatment with precipitating chemicals a wet ashing has been proved to give better results than a dry ashing.
