염기성 염료 Basic Blue 3에 대한 야자계 입상활성탄의 흡착 특성 = Adsorption Characteristics of Coconut Shell-based Granular Activated Carbon on a Basic Dye Basic Blue 3

다국어 초록 (Multilingual Abstract)

In this study, adsorption characteristics of coconut shell-based granular activated carbon (CS-GAC) on Basic Blue 3 (BB3) were evaluated. As the dosage of CS-GAC increased, the removal efficiency of BB3 tended to increase and the initial dye concentration of 50 mg/L was completely removed at 0.2 g dosage. Adsorption equilibrium achieved within 270 and 420 min at the initial concentrations of 25 and 50 mg/L, respectively, and the experimental data were represented by the pseudo-second-order model. The maximum uptakes ($q_{max}$) predicted by the Langmuir model were 34.45, 46.63 and 53.10 mg/g at 298, 308 and 318 K, respectively. The $q_{max}$ value increased as the temperature increased. Also, the Gibbs free energy (${\Delta}G$) was changed to -7.37, -8.19 and -10.40 kJ/mol with increasing temperature. The enthalpy change (${\Delta}H$) and the entropy change (${\Delta}S$) were 34.47 kJ/mol and 0.15 J/mol K, respectively. Therefore adsorption of BB3 by CS-GAC was spontaneous and endothermic.

본 연구에서는 Basic Blue 3 (BB3)에 대한 야자계 입상활성탄의 흡착특성을 평가하였다. 입상활성탄의 투여량이 증가함에 따라 BB3의 제거율은 증가하는 경향을 보였고, 0.2 g 투여량에서 초기농도 50 mg/L의 BB3가 완전히 제거되었다. 흡착평형은 초기농도 25 mg/L와 50 mg/L에서 각각 270분과 420분이 소요되었으며, 실험데이터는 유사 2차 속도식으로 잘 묘사되었다. Langmuir 식에서 예측된 최대흡착량은 298, 308, 318 K에서 34.45, 46.63, 53.10 mg/g으로 온도가 증가할수록 증가하였다. 또한, Gibbs 자유에너지 변화(${\Delta}G$)는 온도 증가에 따라 -7.37, -8.19, -10.40 kJ/mol으로 변화하였고, 엔탈피 변화(${\Delta}H$) 및 엔트로피 변화(${\Delta}S$)는 34.47 kJ/mol과 0.15 J/mol K로 계산되었다. 따라서 야자계 입상활성탄에 의한 BB3 흡착은 자발적이고 흡열적이었다.
