Steam Activation of Acid-Chars for Enhanced Textural Properties and Pharmaceuticals Removal

The present work aims to explore steam activation of sisal or glucose-derived acid-chars as an alternative to KOH activation to prepare superactivated carbons, and to assess the adsorption performance of acid-chars and derived activated carbons for pharmaceuticals removal. Acid-chars were prepared f...

Acid-chars were prepared from two biomass precursors (sisal and glucose) using various HSO concentrations (13.5 M, 12 M, and 9 M) and further steam-activated at increasing burn-off degrees. Selected materials were tested for the removal of ibuprofen and iopamidol from aqueous solution (kinetic and equilibrium assays) in single-solute conditions. Activated carbons prepared from acid-char carbonized with 13.5 M and 12 M HSO are mainly microporous solids composed of compact rough particles, yielding a maximum surface area and a total pore volume of 1987 m g and 0.96 cm g, respectively. Solid state NMR reveals that steam activation increased the aromaticity degree and amount of C=O functionalities. Steam activation improved the acid-chars adsorption capacity for ibuprofen from 20-65 mg g to higher than 280 mg g, leading to fast adsorption kinetics (15–20 min). The maximum adsorption capacities of selected activated samples for ibuprofen and iopamidol were 323 and 1111 mg g, respectively.The authors are grateful for financial support from Spain’s Ministry for the Economy and Business-MINECO (MAT2016-78155-C2-1-R), the Spanish Ministry of Science and Innovation (PID2020-113558RB-C41), the Government of the Principality of Asturias (AYUD/2021/50997), and also Fundação para a Ciência e a Tecnologia (FCT), I.P./MCTES through national funds (PIDDAC), to CQE (UIDB/00100/2020 and UIDP/00100/2020) and IMS (LA/P/0056/2020).
