Abstract
The determination of trace elements in solids by two-step dissolution and the determination of a desired component without dissolving the ma trix (solid phase) was examined. An expression for calculating the tot al of impurity elements in the solid phase from two analytical signals was derived. Experiments performed with various synthetic and natural ly occurring materials demonstrated the applicability of this method t o coprecipitation, chromatography, etc.
