Summary: To expedite the design and production of porous carbons with specific performance characteristics, incorporating machine learning regression into pore size distribution analysis is proposed. A machine learning algorithm was implemented to predict the paracetamol adsorption capacity of porous carbons based on two pore structure parameters: total surface area and surface area of supermicropores-mesopores. The experimental and predicted results for paracetamol capacities using this algorithm were shown to be within the range of experimental uncertainty. This novel approach has the potential to facilitate the production of carbon adsorbents optimized for the purification of aqueous solutions from non-electrolyte contaminants.
