The effects of activated carbon surface features on the reactive adsorption of carbamazepine and sulfamethoxazole

Preparation of ultrafine magnetic biochar and activated carbon for pharmaceutical adsorption and subsequent degradation by ball milling

“…The longer sorption equilibration times for TC with the adsorbents are probably due to the large molecular size of TC. The ultrafine biochar/Fe 3 O 4 and AC/Fe 3 O 4 had faster adsorption of CBZ and TC than traditional porous adsorbents [5,30-32]. The faster adsorption of the CBZ and TC on the biochar/Fe 3 O 4 surface is due to the sorption of the contaminant on the surface of the adsorbent rather than in the micropores.…”

Analysis of sulfamethoxazole and trimethoprim adsorption on sewage sludge and fish waste derived adsorbents

“…WVA1100, a wood-based activated carbon (Mead-Westvaco) adsorbed 0.84 mmol/g of SMX at an equilibrium concentration of 0.1 mmol/L [49]. At the same equilibrium concentration, S208C, a coconut shell based activated carbon (Calgon Carbon) adsorbed 0.73 mmol/g [49].…”

“…WVA1100, a wood-based activated carbon (Mead-Westvaco) adsorbed 0.84 mmol/g of SMX at an equilibrium concentration of 0.1 mmol/L [49]. At the same equilibrium concentration, S208C, a coconut shell based activated carbon (Calgon Carbon) adsorbed 0.73 mmol/g [49]. Other brands of activated carbons adsorbed similar quantities, based on the maximum capacity values obtained from fitting to the Langmuir isotherm (0.73 mmol/g [50] and 0.37e0.64 mmol/g [51]).…”

Assessment of naproxen adsorption on bone char in aqueous solutions using batch and fixed-bed processes

“…On the other hand, the bands of oxygen groups decreased especially those at 1740 and 1630 cm −1 that represent aromatic groups [50,51]. Additionally, there are new bands at 702, 1220 and 1338 cm −1 , which may support the interaction between naproxen and the adsorbent surface [52,53]. Note that the chemical structure of naproxen contains an aromatic ring besides carboxylic and ether groups [54].…”
