dc.description.abstractThis study reports the analysis data of diclofenac sodium adsorption on sycamore ball activated carbon surface, in which various parameters such as adsorbent dosage, initial diclofenac sodium concentration, temperature, and pH were analyzed. At 25 degrees C, adsorbent dosage was used the range from 2.5 mg/50mL to 30 mg/50mL, and initial diclofenac concentration was taken from 10 mg/L to 50 mg/L. For adsorption temperature effect, adsorption temperature was investigated from 25 degrees C to 45 degrees C by holding adsorbent dosage constant (10 mg/50mL). By holding constant adsorbent dosage of 10 mg/50mL, contact time effect from 0 to 210 min was investigated with initial DS concentrations of 10, 20, 30, 40, and 50 mg/L. To examine pH effect, pH parameters were adjusted from 2.84 to 10.20. Besides, adsorption isotherm model, kinetic and thermodynamic studies carried out in this study are given. Langmuir isotherm model was determined to be the best fitting isotherm model for diclofenac sodium adsorption on sycamore ball activated carbon. Also, the maximum sodium diclofenac adsorption on sycamore ball activated carbon was calculated 178.89 mg/g at 25 degrees C, and kinetic data displayed that this adsorption occurred quite fast. Pseudo-first and pseudo-second order models were applied for sodium diclofenac adsorption on sycamore ball activated carbon, and the correlation coefficient values of 1.000-0.998 indicate that this adsorption was well fitting with pseudo-second order model. Moreover, from the thermodynamic study, sodium diclofenac adsorption on sycamore ball activated carbon was found to be exothermic, spontaneous, and feasible. Thus, the results obtained from this study confirmed that sycamore ball activated carbon is an economically suitable and effective adsorbent for sodium diclofenac adsorption.en_US
