[Atomic absorption determination of mercury vapors in the air of the work environment]

The concentration of mercury vapors in air samples obtained from work-environment may be determined by atom-adsorption technique. To this end, the most appropriate air absorption speed proved to be 0,3 dm2/min through sulphuric acid solution of potassium pemanganate. Additional oxdation of samples was performed with a mixture of sulphuric acid and nitric acid in proportion 2:1. a 24 per cent rise in the height of the adsorption peaks was thus achieved, because of reduced losses.
