초록

최근 해수 산업폐수 등의 수계로부터 중금속 이온의 제거 및 회수를 위한 기술로서 고분자 하이브리드 젤을 이용한 흡착법이 매우 효과적인 방법의 하나로 대두되었다. 본 연구에서는 카테콜(catechol) 그룹을 포함하는 도파민(dopamine)으로 수식된 폴리아스팔트산, PASP-DOP, 고흡수성 하이드로젤을 제조하고, 그 팽윤 거동과 금속이온 특히 납이온, Pb(II), 에 대한 흡착 물성을 수식이 안된 PASP 젤과 비교적으로 조사하였다. 카테콜 그룹은 여러 다른 중금속 이온에 대해 강한 배위 결합능을 나타내는 것으로 알려져 있다. PASP-DOP 젤은 40~70 g/g의 수팽윤비를 갖고, Pb(II) 금속이온에 대해 매우 높은 흡착능을 나타내었다. 흡착 거동에 미치는 접촉시간, 서로 다른 pH, 온도 및 농도의 영향을 조사하였다. SEM과 FTIR을 통해 젤의 다공성 모폴로지 및 금속이온과 고분자 구조간의 상호interaction을 고찰하였으며, 또한 농도에 따른 흡착량 데이터로부터 흡착 isotherm을 이론식에 적용하여 분석하였다. 본 연구결과로부터 PASP와 PASP-DOP 가교젤이 폐수 중의 납이온 제거에 효과적인 흡착제로 응용 가능할 것으로 사료된다.

Adsorption using polymeric hybrid gels is regarded as one of the most effective methods to remove heavy metal-ions from aqueous solution. In this work, superabsorbent gel based on dopamine (containing catechol group) conjugated polyaspartate (PASP-DOP) was prepared, and the swelling behavior of PASP-DOP gel and the metal-ion adsorption, specifically for Pb(II), properties of PASP-DOP gel were investigated as compared with unmodified PASP gel. The catechol functional groups are known to exhibit a strong non-covalent binding to various heavy metal ions. PASP-DOP gel possessed swelling degrees in the range of 40~70 g/g in water, and exhibited very high adsorption capacity for lead ion. The effects of contact time, pH, temperature, and metal-ion concentration on the adsorption were investigated. The gel morphology and interaction between polymer and metal-ion were characterized by using SEM and FTIR spectroscopy, and also the related adsorption isotherm was analyzed by using theoretical models. The results indicate that PASP and PASP-DOP can be used as an effective adsorbent for the treatment of waste water contaminated with Pb(II) ions.
