Abstract

On the base of fibrous ion exchangers, indicator materials were obtained for sorbates of an alkaline and acidic nature, intended to visualize the working time of the filter layer during ion exchange air purification. The optimal conditions for their production and operation were determined. The practical applicability for the manufacture of indicator cartridges for filters of deep air purification and personal protective equipment for human respiratory organs and skin with the aim of timely visualizing of the sorption resource depletion, due to the contrast and sensitivity of the color change, was demonstrated.
