NANOTECHNOLOGICAL METHOD OF DETERMINING PRESENCE AND QUANTITATIVE CONTENT OF RARE AND DISPERSED CHEMICAL ELEMENTS IN ROCKS, ORE AND PRODUCTS FROM THEIR PROCESSING

摘要

FIELD: chemistry.;SUBSTANCE: method can be used particularly in searching for mineral deposits and ecological monitoring. From a sample of analysed rocks and/or ore and/or products from their processing and deionised water, taken in ratio of 1:10, a colloidal salt solution is prepared, containing particles of a fraction of the analysed sample with size of 1-1000 nm. The obtained solution is taken of for mass spectrometric analysis with inductively coupled plasma for presence of rare and dispersed elements and simultaneously for determination of their quantitative content. Presence and quantitative content of said elements in analysed rocks and/or ore and/or products from their processing is indicated by reaching corresponding detection limit values.;EFFECT: increased reliability of results with reduction of expenses on analysis.;2 cl
