Abstract
The adsorption processes of phenol from aqueous solution onto a activated carbon from cassava root (AC) and a modified activated carbon (MAC) with cationic surfactant cetylpyridinium chloride (CPC) was investigated. AC was mixed with a surfactant solution of 0.45, 0.9 and 1.8 mM with correspond with 0.5, 1.0 and 2.0 time critical micelle concentration (cmc). The results showed that the MAC with a surfactant solution of 0.45, 0.9 and 1.8 mM have a higher surface area compared with the AC. Adsorption isotherm onto the AC or MACs was investigated in a batch adsorption experiment in order to obtain the optimum conditions for the phenol adsorption process. Experimental equilibrium data was obtained and correlated with Langmuir and Freundlich isotherms. The results are shown that the Langmuir isotherm model better fits the experimental data compared with the Freundlich isotherm for both AC and MAC. It was found that the MACs with a surfactant solution of 0.45, 0.9 and 1.8 mM CPC have a higher phenol adsorption capacity, with 0.0131, 0.0106 and 0.0137 mmol/g, respectively, compared with AC, which has a capacity of 0.0056 mmol/g. It can be conclude that MAC with 1.8 mM CPC is available for highest amount of phenol removal.
