Abstract
본 연구는 자성 야누스 미세 흡착제를 합성하기 위해 쉽고 빠르며 대량생산이 가능한 원심력 기반 미세유체 반응기
를 개발하였다. 두 개의 정렬된 주사침과 원심분리 튜브로 구성된 다중 미세노즐을 사용함으로써 높은 균일도를 갖는
프러시안 블루와 자성 나노입자의 함입이 이루어진 미세 흡착제(PB-MNP-MAs)를 합성하였다. 등온흡착과 흡착속도
실험을 통해 다공성 구조 및 프러시안 블루 나노입자의 넓은 비표면적을 갖는 미세 흡착제의 향상된 세슘 흡착 성능
을 증명하였으며 이를 통해 10분 이내의 빠른 흡착을 유도할 수 있다. 흡착 공정 후, 외부 자기장 도입을 통해 세슘 수
용액 내에서 합성된 PB-MNP-MAs를 성공적으로 회수하였다. 따라서 본 연구결과를 바탕으로 생물 및 환경 제염 분
야에서 기능성 흡착제 발전을 위한 새로운 방향성을 제공해 줄 것으로 기대한다.
Here, we develop a centrifugal microfluidic reactor with simple, fast, and high-throughput manner for the
generation of magnetic Janus micro-adsorbents (MAs). By using the multi-micronozzle consisting of two separate aligned
needles and centrifugal tubes, we have synthesized highly monodispersed Prussian blue- and magnetic nanoparticle-laden
micro-adsorbents (PB-MNP-MAs). The enhanced cesium (Cs+
) adsorption was demonstrated by conducting the adsorption
isotherm and kinetics experiment which can be contributed to the porous nature of the Ca-alginate networks with a high surface area
of embedded PB nanoparticles, resulting to perform rapid adsorption activity within 10 min. After Cs+
adsorption process, the
as-synthesized PB-MNP-MAs were successfully harvested by introducing the external magnetic fields. Therefore, we believe that
our findings can be provided new direction towards the development of advanced functional adsorbents in biological and
environmental fields.
