Способ относится к метрологии аналитической химии и может быть использован при градуировке средств измерения для анализа газов на содержание сероводорода. Сущность способа: для упрощения процедуры изготовления стандартных образцов вначале готовят раствор растворимой соли металла, например ацетата кадмия, затем точно известное количество металла наносят на инертный носитель, например бумагу, переводят весь металл в сульфид, воздействуя на него сероводородом, и удаляют избыток сероводорода и растворитель.The method relates to the metrology of analytical chemistry and can be used in the calibration of measuring instruments for the analysis of gases for the content of hydrogen sulfide. The essence of the method: to simplify the procedure of making standard samples, first prepare a solution of a soluble metal salt, for example cadmium acetate, then a precisely known amount of metal is applied on an inert carrier, for example paper, the whole metal is converted to sulfide, affecting it with hydrogen sulfide, and the excess hydrogen sulfide and solvent are removed .
