Abstract
The basic principles of synthesis of granulated indicator adsorbents of the new generation with a visual determination of the moment of the operation end are described in the present paper. Adsorbents are designed to equip the gas analyzers filter systems. They are able selectively remove from the gas mixture components complicating the normal operation of sensitive elements. The important feature of the absorbents is their color change in the absorption process that is fixed visually through the transparent wall of the filter. Thanks to this important quality it is easily possible to determine the time of replacement of the adsorbent in the filter. We used granular macroporous ion exchangers as a basis for the creation of such adsorbents. As a result of specific chemical modification these adsorbents can selectively extract from the analyzed gas mixtures such interfering components as halogens, amines, NH3, SO2, H2S, HCl, HF, HI, HCN, NO2, O3, SiF4 and NO.
