A method for indication of carbon monoxide through dyeing reactive applied on solid carrier – silica-gel, at passing gas through it, wherein which one uses a transparent cell with water solution of potassium permanganate KMnO(chemically pure or analytically pure) in distillated water in amount of 0.02 mol or 3.16068 g in 1 l (0.1 N solution) at a temperature within 5 and 40 °C, and by change of intensity of color from violet-crimson to grey or to total decoloration one determines presence and concentration of carbon monoxide CO in air-gas mixture bubbled through volume of indicator, by the scale of pre-calibrated device. |
