DETERMINATION OF THE TOXIC TRACE ELEMENT CONTENT OF INDUSTRIAL WASTES BY X~RAY FLUORESCENCE ANALYSIS WITH ISOTOPE EXCITATION. INVESTIGATION OF PAINT WASTES

Abstract

The concentration of the metal components of wastes originating from paints used in various fields was determined, with particular regard to toxic elements. It was established on the basis of measuring results that wastes generally contain more than one toxic element in different quantities. These elements reveal different mobilities in media of different pH, so that the probability of their getting into the environment considerably varies for the single elements. The deposition of wastes of this type on the soil can be considered as safe. if the migration of the toxic elements is reduced to a minimum.
