Özet
The present study relates to the physicochemical investigation of the methylene blue, diclofenac, and copper(II) sorptions from the water of the new activated carbon (RPAC) prepared in single-step KOH-activated pyrolysis from red pepper (Capsicum annuum L.) industrial processing pulp (RP) under optimized conditions. Sorption conditions were optimized according to the maximum effects of key factors (RPAC dosage, sorbate concentration, interaction time, and temperature) affecting sorption processes at their natural pH in water. The kinetic and equilibrium experimental sorption data of the examined sorbates were simulated to widely used models and found to fit well with the pseudo-second-order and Langmuir models, respectively. The maximum sorption capacity for methylene blue, diclofenac, and copper(II) by RPAC was found to be 322.6, 303.0, and 196.1 mg g(-1) at their natural pH and 50 degrees C, respectively. Thermodynamic parameters determined for each sorption system indicated that the sorption processes were endothermic and spontaneous. The outputs of the present study highlight that RPAC can be used as an effective sorbent in removing contaminants from water.
