Influence of mineralization and analysis technique on the results of determination of iron and nickel in industrial wastes

An analysis of industrial wastes is a difficult and complicated procedure b ecause of their complex contents which depend on the nature of production a nd technology being used. The present paper gives selected analytical probl ems concerning the determination of nickel and iron in wastes coming from t he metalurgical industry. It has been concluded that the methods of mineral izing wastes need to be adjusted to their complexity. For emulsion wastes t he most suitable method is microwave mineralization.
