Application of Inductively Coupled Plasma Atomic Emission Spectroscopy Analysis with a Polychromator/Monochromator Combination to the By-Products of Coal-Fired Power Stations

摘要

The by-products of coal-fired power plants may be hazardous for the environment. Good analytical methods are therefore required in order to establish either a possible usage of the by-products or their possible storage. Preliminary experiments carried out with inductively coupled plasma atomic emission spectroscopy have proven very successful. Moreover, the method is cost-effective. A short description is given of an optimized system for routine analysis. The system consists of a 2- and a 15-channel polychromator in combination with a monochromator. The opportunities it provides are also described. Use of the monochromator to analyze coal and run-off water from the flue-gases desulphurization, and of the polychromators to analyze coal fly-ash is described separately.
