It is essential to focus on the removal of phenol from contaminated water due to its harmful effects on humans. Recently, the circular economy has drawn a lot of interest since it attempts to reduce waste and continually use resources. When creating new value goods in a circular economy, resource recovery employs recovered garbage as the primary raw material. This research focuses on a low-cost approach that employs hydrothermal calcination and acids activation to create an activated carbon (AC) adsorbent from used cation exchange resin. SEM, XRD, ICP, and BET were used to analyze the surface chemistry and structure of AC. It was discovered that the bases and acid treatment might enhance the number of pores and functional groups on the AC surface that contain oxygen. According to experimental findings, AC modified with HCl had the maximum efficiency of phenol removal, demonstrating the influence of acidification on AC's adsorption ability. To match the experimental data, Freundlich and Langmuir adsorption isotherms were used. [ABSTRACT FROM AUTHOR] |
