Abstract
This study aimed to assess the effectiveness ofactivated carbon (AC) in removing methomyl from water. Batchand fixed-bed column experiments were conducted toinvestigate the potential of AC for methomyl adsorption and toidentify the optimal conditions for its application in watertreatment. The batch experiments determined that activatedcarbon could adsorb methomyl at a rate of 32.70 mg/g after 300m of contact. The highest adsorption capacity of 35.35 mg/g wasobserved at pH 2. Further agitation speed experiments revealedthat turbulence is critical in controlling the solid–liquid masstransfer mechanism. The result from the pseudo-first-orderadsorption kinetic equation was consistent with theexperimental data, and the Langmuir adsorption isothermbetter described the methomyl adsorption of activated carbon.The fixed-bed column experiments showed that the adsorptionefficiency was depleted after continuous use after 19 hours(1,140 m), corresponding to the adsorption equilibrium point.
