Abstract
The aim of the study was to assess the effects of input parameters on the value of dynamic sorption capacity of
small protective filters used in the civil protection of the Czech Republic. Relative humidity, the concentration of the test
substance/air mixture, type of filter, year of manufacture, batch and type of sorbent, were used as the monitored parameters.
The measurements were performed using a gas-air mixture bas ed on cyclohexane, ammonia, sulphur dioxide, chlorine and
sulfane. MOF, MOF-2, MOF-4, MOF-5 and MOF-6-M filters were used for the measurements. It has been detected that the
tested filters in many cases meet the requirements of the relevant Standard for sorption capacity, namely in cases of
cyclohexane, sulfane and sulphur dioxide. It has also been established that MOF-4 filters containing medium-grained sorbent
SZS-1000 attained lower values of sorption capacity than filters with CHS-5 sorbent.
