TO THE QUESTION ABOUT DETERMINATION OF FREE SIO2 IN VARIOUS INDUSTRIAL AEROSOLS DURING REALIZATION OF HYGIENIC CONTROL

Research Institute for Medico-Ecological Problems of Donbass and Coal Industry, Donetsk

Full article (PDF), RUS

The comparative evaluation of determination methods of free SiO2 including amorphous and crystalline in the industrial aerosols in the working zone air was realized. Factors, which bring to substantial errors were revealed. The optimal conditions of reactions realization were selected. Unification of the method of spectrophotometric determination of free SiO2 concentra¬tion in the working zone air in the dust aerosol in diapason of mass portion content from 1 to 100 % was proposed.

Key words: free SiO2, determination method, working zone air
