Abstract

The objective of this study is to remove phenol from aqueous solution by using modified industrial solid waste (ISW) in the presence of cationic and anionic surfactant with batch adsorption. Tests were carried out as functions of contact time, initial phenol concentration, pH and temperature. The experiments demonstrated that maximum phenol adsorption removal was obtained in a wide pH range of 3-13 and it took 3 h to attain adsorption equilibrium. With an increase of temperature, phenol adsorption amount decreased. The mechanism of phenol adsorption onto ISW adsorbents in the presence of cationic and anionic surfactants was discussed. There are two main mechanisms. Mechanochemistry effect improved adsorption capacity of ISW adsorbents by having particles ground finer and activated; and then in the presence of surfactants, zero point charge of adsorbents surface was major factor to influence combination of adsorbents with surfactants and adsorption capacity of organic-ISW adsorbents
