초록

본 연구에서는 석탄계 입상활성탄을 이용하여 수용액으로부터 염기성 염료 Basic Blue 3 (BB3)의 흡착에 대해 조사하였다. 모든 실험은 회분공정에서 수행하였고, 활성탄의 투입량, 접촉시간, 초기농도 및 온도와 같은 흡착변수들에 대해 평가하였다. 활성탄의 투입량이 증가할수록 BB3 제거율도 증가하였으며, 활성탄 0.2 g 이상에서 초기농도 50 mg L-1의 BB3가 100% 제거되었다. 또한, 흡착평형에 도달하는 시간은 염료의 초기농도에 의존적이었다. Langmuir 모델에 따르면, 석탄계 입상활성탄의 최대흡착량은 25, 35, 45 ℃에서 66.45, 84.97, 87.19 mg g-1으로 산출되었다. 그리고 Gibbs 자유에너지 변화량, 엔탈피 변화량, 엔트로피 변화량과 같은 열역학적 변수들에 대해 평가하였다.

This research studied the adsorption of basic dye, Basic Blue 3 (BB3) by using coal-based granular activated carbon (C-GAC) from aqueous solution. All experiments were performed in batch processes, and adsorption parameters such as C-GAC dosage, contact time, initial dye concentration and temperature were evaluated. The removal efficiency of BB3 was increased with increasing the C-GAC dosage and 100% of initial concentration, 50 mg L-1 was removed above 0.2 g of C-GAC. Also, the time to reach equilibrium depended on the initial dye concentration. According to the Langmuir model, the maximum uptakes of C-GAC were calculated to be 66.45, 84.97 and 87.19 mg g-1 at 25, 35 and 45 ℃, respectively. In addition, thermodynamic parameters such as Gibbs free energy change, enthalpy change and entropy change were investigated.
