Abstract

Adsorption isotherms were measured for ammonia on untreated FB4 activated carbon, FB4 activated carbon impregnated with ZnCl<sub>2</sub>, and on activated carbon from anti-ammonia filter ( Leipzig, F.R.G.). The potential theory was applied to the measurements. The Dubinin-Radushkevich plot in linearized coordinates for sorbents of the first structural type revealed that the Czechoslovak FB4 activated carbon possesses a bidisperse structure, giving two linear segments in the plot. The sample from the filter, which served as a reference material, exhibited a single straight line in the plot. The measurements were supplemented by the mercury porosimetry determination of the differential distribution curves. The three types of activated carbon were characterized by emission spectral analysis. The characteristic curve enables the equilibrium adsorption to be converted to different pressure and temperature conditions, and thus it is a suitable method for trapping ammonia in freezing stores to protect foods in case of leak of coolant.
