This study focuses on the investigation of the capability of surfactant-modified bentonite for removal of phenol from aqueous solution. Calcium bentonite was beneficiated by means of ion exchange method using sodium trioxocarbonate (IV) resulting into sodium exchanged bentonite (SEB) and modified using ion exchange method, impregnation method, mechanical mixing methods using quaternary hexadecyltrimethylammonium bromide (HDTMABr). Fourier Transform Infra-Red Spectroscopy (FTIR) technique was used to study the vibrational bands of the sodium exchanged bentonite and modified SEB respectively. The effects of contact time, pH and initial concentration were studied on SEB and surfactant-modified SEB. The result reveals that the removal of phenol using SEB and surfactant-modified bentonite has optimum pH, contact time and equilibrium adsorption capacity of 6.0, 60 mins and 22.4 mgg-1.. View More»
