Semenenko Institute of Geochemistry, mineralogy and Ore Formation popup.description2 As object of research rocks, minerals, soils, waters in territory of Ukraine, standard samples of rocks served. The work purpose - working out of techniques of definition of the maintenance of rare, colour, noble and is rare-ground metals in minerals and breeds method ICP-MS. Optimum physical and chemical conditions of dissolution of rocks and minerals with use of microwave radiation are established. The 8 analytical schemes (silicate and carbonate breeds, minerals and soils) and definition in them and rare elements are developed. The optimum structure and concentration of solvents (acids HF, HCl, H2SO4) and more smoothly LiBO2, H3BO3, Na2O2 is defined; and also optimum parametres of mx-processing - temperatures, time, pressure and frequency, for dissolution of geological objects in microwave ЕТHOS firms MILESTONE (Italy). The conducted researches and developed techniques ICP-MS of definition of elements such as selenium, arsenic, mercury, cadmium, and molybdenum give the chance to expand geochemical methods of searches of minerals and geochemical monitoring of an ecological state of environment.
