Keywords:

In the present article, the regularities of the adsorption differential enthalpy of hydrogen sulfide molecules on an activated carbon adsorbent obtained from the bark of the Paulownia tomentosa tree at a temperature of 303 K, depending on the adsorption value, as well as the mechanism of the sorption process, were investigated. From the stepwise change of the adsorption differential enthalpy of hydrogen sulfide molecules on the activated carbon adsorbent from the bark of the Paulownia tomentosa tree, it was determined that the number of active sites with respect to hydrogen sulfide is 0.25 mmol/g, and the formation of a pentamer complex of adsorbate/adsorbent in the ratio of 5H2S:adsorbent was established.
