초록

본 연구에서는 EVA를 바인더로 사용하여 우레탄 폼(PU)에 LMO를 고정화한 PU-LMO를 제조하였다. XRD 및 SEM 분석을 통해서 EVA에 의해 LMO가 폴리우레탄에 잘 고정화된 것을 확인할 수 있었다. PU-LMO를 제조시에 EVA/LMO의 최적비율은 0.26이었다. PU-LMO에 의한 리튬이온의 흡착 속도는 유사 2차 속도 모델식에 잘 부합하였다. 평형실험 데이터는 Langmuir 흡착 등온식에 잘 적용되었으며, 최대 흡착량은 17.09 mg/g이었다. PU-LMO는 리튬이온에 대한 분배계수(Kd)가 다른 금속들의 Kd 값에 비해 높게 나타나 뛰어난 리튬 이온 선택성과 높은 흡착량을 보였다.

In this study, PU-LMO was made by immobilization of LMO on urethane foam (PU) with using an EVA as a binder. PU-LMO was characterized by using X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM). The optimal ratio of EVA/LMO for preparation of PU-LMO was 0.26 gEVA/gLMO. The adsorption of lithium ions by PU-LMO was found to follow the pseudo-second-order kinetic model. The equilibrium data fitted well with Langmuir isotherm model and the maximum removal capacity of lithium ions was 17.09 mg/g. The PU-LMO was found to have a remarkably high selectivity of lithium ions and high adsorption capacity because the distribution coefficient (Kd) of lithium ion was higher than those of other metal ions.
