Conventional treatment process cannot meet the need for treatment of produced water from surfactant flooding of Enhanced Oil Recovery (EOR) field. In this study, adsorption of surfactants using commercialised adsorbent, CrudeSorb and natural adsorbent, kaolin were investigated to assess the removal of surfactants from synthetic produced water. Adsorbents were first sent for XRD to verify theirs mineralogical and SEM to determine their external morphology texture. In the adsorption test, the adsorbents were exposed to anionic surfactants in produced water and final surfactant concentration of produced water is measures using titration method. The amount of surfactant that was adsorbed was quantified by subtracting the concentration of surfactants after adsorption from the initial concentrations. The surfactant removed was optimized at pH value of 2 for kaolin, and pH12 for CrudeSorb. An increase in of contact time also increases the percentage removal of surfactants from produced water on both CrudeSorb and kaolin. The adsorption activities for both CrudeSorb and kaolin fitted the Langmuir Isotherm with correlation coefficients of 1.00 and 0.9962. The adsorption activities also found to be fitted the pseudo second-order reaction kinetic model at correlations coefficients value of 0.9993 and 0.9923 respectively.
