Laboratory apparatus for evaluation of sorption capacity of solids



Laboratory apparatus for evaluation of sorption capacity of solids



Science of the Total Environment 39(3): 281-290



The design of laboratory apparatus for the evaluation of the sorption capacity of solid sorbents which collect air pollutant particles was described. The apparatus, which was easy to set up in any laboratory, consisted of 3 basic elements: a standard mixtures generator, utilizing permeation through a PTFE membrane, a sorbent trap of controlled temperature and a flame-ionization detector. The appartus enabled investigation of the effect of various parameters (concentration, flow rate, temperature, co-adsorption, etc.) on sorption capacity, as measured by breakthrough parameters (breakthrough volume and time), and studies of the fundamental parameters of the remaining steps (sample storage, desorption and final determination) of the analysis.
