Canarium Odontophyllum Waste-Based Activated Carbon for COD Reductions In Textile Wastewater

Abstract

Abstract: It has been successfully studied how to synthesize activated carbons from the seeds of Canarium odontophyllum (COAC) via physicochemical activation. Carbon dioxide (CO2) gasification and potassium hydroxide (KOH) impregnation were used to do physicochemical activation. The reduction of COD in industrial textile effluent was used to assess the COAC's adsorption efficacy. Using an experimental methodology, the findings showed that the adsorption performance for all pollutants was significantly influenced by the activation temperature, activation time, and KOH impregnation ratio (IR). The ideal COAC preparation parameters were 798℃ for activation temperature, 1.16 hours for activation time, and 2.65 for IR. COAC resulted in a 64.10% decrease in COD. The Langmuir model provided the best fit for the adsorption of the adsorbate onto COAC.
