The sampling of hydrogen sulfide in air with impregnated filter paper

Abstract

A method is proposed for the quantitative collection of hydrogen sulfide in air on impregnated filter paper. An aqueous solution of potassium hydroxide, potassium zincate and glycerol is used as impregnating fluid. The stability of the collected sulfide and the efficiency of collection at different humidities, temperatures, hydrogen sulfide concentrations and air velocities were determined.
