In this study, BAX950 activated carbon;a wood-based activated carbon with particle size fraction 1-2 mmwas developed to investigate adsorption dynamics and isotherms of target volatile organic compounds. The adsorption of various volatile organic compound were analysed by intelligent gravimetric analyserto understand their barrier to diffusion on the activated carbon, which may affect the performance of the carbon filters in real situations.. These toxic organic compoundswas effectively removed by BAX950 activated carbon filters as both hydrophilic functionalities and hydrophobic graphene layers are present in the material acting as primary adsorption sites for hydroxyl groups and hydrocarbons respectively.The activation energies correspond to changes in surface coverage, which showed highest values at low relative pressure where molecular sieving occurs.
