Celju studii jest dat ocenku ispolzovanie poverchnostnyj adsorbent na baze dejstvennogo ugolja dlja podgotovku nesložnogo filtra v odnokratnom kapjušone prednaznačennogo k utečke iz sredi zaražennogo gazoobraznogo vrednogo veščestva pri avarii.

The aim of the study is to evaluate the use of surface adsorbents on the basis of active carbon for the construction of simple filter for a one-shot hood intended for the escape of people from environment contaminated by gaseous harmful substances in accidents. The article gives basic information on selected surface adsorbents and barrier materials used most often for the construction of one-shot protective agents. The conductometric method used for the evaluation of protective qualities of these materials against selected harmful substances with acid-base properties under dynamic and static conditions and the design of a newly developed Teflon permeation vessel using carbon electrode instead of standard platinum electrode are described. This article deals with the evaluation of protective properties of selected textile adsorbent SARATOGA with spherical active carbon under static and dynamic conditions by the above method that represents a modification of the US norm ASTM F 739 (ČSN EN ISO 6529). Hydrochloric, nitric and sulphuric acids, ammonia, piperidine and cyclohexylamine, especially acetic acid and a-butylamine were used to test protective qualities of the above textile adsorbent.
