FIELD: chemistry.
SUBSTANCE: iodide monofractions are prepared. Luminescence is excited in the said fractions with subsequent determination of the mineral. Luminescence is excited using X-ray beams. The X-ray luminescence spectrum is recorded in the 600-800 wavelength range and the mineral is determined from fluorescence intensity, taking into account that marshite radiation is an order higher than radiation of miersite and by three-four orders more intense that that of iodoargyrite.
EFFECT: rapid and reliable pre-assessment of the composition of iodides.
