Abstract： Inorder todevelop eficient Volatile OrganicCompounds （VOCs）adsorbent materials，anew typeofactivated carbonis prepared through multi-element synergistic modification，and its performance is evaluated through fixed bed adsorption experiments.Research has found that at a temperature of 25 °C ，nitrogen doped modified activated carbon has a maximum adsorption capacity of 298mg/g for toluene，and boron phosphorus synergistic modification significantly improves the material's moisture resistance.Modified activated carbon maintains 92% adsorption capacity after 1O cycles of adsorptiondesorption，withstable materialstructureandstrongselectivity，ithasimportantapplicationprospects inthefield of industrial VOCs treatment.
