Abstract

Oak wood based activated carbon was modified with surface impregnation of $Fe^{3+}$ and $Al^{3+}$ metal ions mixture for enhancements of phosphate adsorption capacity in aqueous solution. The phosphate adsorption capacity of the prepared metal impregnated carbon (MC) was about 8 times higher than that of the original activated carbon (OC). Adsorption equilibrium capacities of the phosphate increased with increasing system temperature. The adsorption equilibrium isotherm of phosphate on the prepared MC could be represented by the Langmuir equation. Thermodynamic parameters also indicated that adsorption system was spontaneous and endothermic reaction. The internal diffusion coefficient was measured to analyze the adsorption behavior and kinetic rate. To determine the internal diffusion coefficient, pore diffusion model (PDM) was employed and the result was in good agreement with experimental data.

수계에 존재하는 인산염의 흡착제거 용량을 향상시키기 위하여, 참나무 기반 활성탄을 제조하였으며, 이때 $Fe^{3+}$와 $Al^{3+}$이온의 혼합물을 흡착제 표면에 담지 하였다. 금속담지 활성탄의 인산염의 흡착용량은 금속이온으로 표면을 개질 하지 않은 활성탄에 비해 약 8배 높게 나타났다. 흡착평형량은 흡착반응의 온도가 증가할수록 증가하였으며, Langmuir 흡착등온식의 경향과 일치하였다. 제조된 금속담지 활성탄의 인산염 흡착제거공정은 흡열의 자발반응으로 진행되었음을 확인하였다. 흡착공정의 거동과 제거속도를 평가하기 위하여, 세공확산모델을 통해 내부 확산계수를 산출하였으며, 이는 실험결과와 매우 일치하였다.
