FIELD: chemistry.
SUBSTANCE: method includes pretreating a sample with an inorganic reagent and determining silicon using a spectrometric method based on a blue-coloured silicon-molybdenum complex followed by re-calculation for silicon dioxide, wherein the reagent used is 20% borofluorhydric acid and treatment is carried out at 70±2°C for 40 minutes.
EFFECT: high selectivity of analysis.
