For the first time, the fundamental energetic characteristics of hydrogen sulfide (H₂S) adsorption on an activated carbon sorbent derived from the wood of the hybrid form Paulownia tomentosa were determined using adsorption microcalorimetry. The differential values of Gibbs free energy were calculated. It was established that the concentration of active sites for hydrogen sulfide on the activated carbon adsorbent derived from the bark of Paulownia tomentosa is ~0.35 mmol/g. It was proven that, in general, hydrogen sulfide molecules form 4H₂S/adsorbent complexes on the activated carbon adsorbent derived from the bark of Paulownia tomentosa.
