LAURA-CRISTINA RUSU NI, CR, CO DETECTED IN SOME MATERIALS TESTED ACCORDING TO EUROPEAN STANDARDS
This study was designed to determine the composition of three representatives of the class of materials widely used in dentistry through the cation analysis method in spectrometry by atomic absorption. We performed two measurements: the cations extraction in Aqua Regia and cation extraction in artificial sweat. Our purpose is to analyze the nominal composition in Ni, Cr, Co of the materials used in these tests according to ISO standards<7>.
