Abstract

In this work, we reported the successful conversion of the industrial SLS originated from black liquor to low-cost porous carbon with tunable microstructure and ultrahigh adsorption performance of tetracycline (TC) from water via pre-carbonation and KOH activation. Comparatively, LCA-850-4 with a very high specific surface area (2805.8m²/g) and pore volume (1.45cm³/g) showed a maximum adsorption of 1173mg/g at 298K, which was far higher than other reported adsorbents. LCA-850-4 exhibited excellent adsorption over a broad pH range. Kinetics and isotherm data was well fitted to the pseudo-second-order rate and Langmuir model, respectively. Thermodynamic parameters indicated a spontaneous and endothermic adsorption. The results are of importance to indicate LCA-850-4 with fast kinetics and excellent reusability possessed the huge potentials in practical pharmaceutical antibiotic wastewater treatment.
