표면 개질 열처리된 활성탄의 수용액상 페놀 흡착 특성 = Adsorption Characteristics of Phenol in Aqueous Solution using Surface-modified and Thermal Treated Activate Carbon

다국어 초록 (Multilingual Abstract)

In this study, the removal rate of phenol in aqueous solution was evaluated using surface-modified activated carbon (AC). The physical and chemical properties of AC and surface-modified AC (AC-K800) were analyzed with scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET), and fourier transform infrared spectroscopy (FT-IR), and phenol adsorption was characterized using Freundlich and Langmuir model equations. The phenol adsorption efficiency of AC-K800 was significantly improved above 97% of initial concentration(50mg/L) by pre-treatment. The maximum adsorption capacity (44.40 mg/g) of phenol by AC-K800 was observed at a slightly acidic condition (pH 4). From the kinetic experiment results, it was shown that the adsorption equilibrium was attained after 360 mins. The kinetic data showed good fitting with the pseudo first and second order models (R2 >0.990). The equilibrium adsorption of phenol well fitted by the Langmuir model and the adsorption capacity was 326.55 mg/g. From these results, it was concluded that AC-K800, as a pretreated absorbent, can be successfully applied to remove phenol from the aqueous solution.
