| 520 | _aThe carob waste is an eco-friendly, economical, and effective adsorbent however it has never been studied before for removing pesticides from water. This study examined the possible application of carob waste powder treated with potassium hydroxide (KOH) as a substitute adsorbent for removing methidathion pesticide from water. The adsorbent was characterized by X-ray diffraction, Brunauer-Emmett- Teller, Fourier-transform infrared spectroscopy, Scanning electron microscope (SEM) and particle size analyser. pH, adsorbent dose, contact time, temperature, and initial concentration of methidathion pesticide were among the experimental factors that were elucidated. The results showed that solution pH 5 and 2 g/L adsorbent dose were the optimum conditions at an equilibrium time of one hour and 25 °C. Linear isotherm had the best fit to the experimental data with a correlation coefficient R2 of 0.95 and pseudo second order described the kinetic data well with an R-square ≥ 0.98223. The adsorption capacity of the adsorbent increased with the increasing temperature indicating an endothermic process. The highest amount of methidathion adsorbed by the KOH treated carob waste was recorded as 21.3 mg/g comparable and higher than the adsorption capacity of alternative sorbents reported in the literature. Although the adsorption process requires further optimization, the findings revealed that KOH treated carob waste show to be a promising adsorbent for the removal of pesticides from aqueous solutions. | ||
