초록

수산계 폐기물로부터 분리한 chitin을 epichlorohydrin과 반응시켜 가교 chitin을 제조한 후 탈아세틸화하여 가교 chitosan을 제조하였다. 가교 chitosan-OH를 가교 chitosan-Cl로 전환시킨 뒤 킬레이트 시약인 2,2'-Iminodibenzoic acid 염과 반응시켜 킬레이트 흡착제인 2,2'-Iminodibenzoic acid-가교 chitosan을 합성하였다. 그리고 합성된 흡착제를 이용하여 Pb(II), Cu(II), Cd(II)의 흡착과 회수 특성을 연구하였다. 흡착특성에 대한 실험 결과, pH가 증가할수록 흡착되는 금속 이온의 양이 증가함을 알 수 있었다. 최적 반응시간은 1시간, 흡착력은 Cu(II)

Abstract

Crosslinked chitin was prepared from epichlorohydrin and chitin which was isolated from waste marin source. The crosslinked chitosan were prepared by the deacetylation of the crosslinked chitin with a strong base. 2,2'-Iminodibenzoic acid-crosslinked chitosan was prepared by reacting 2,2'-Iminodibenzoic acid salt with crosslinked chitosan-Cl which was obtained by chlorination of crosslinked chitosan. The adsorptivity of Pb(II), Cu(II), Cd(II) was studied as a synthetic adsorbent. Experimental results for the adsorption and the recovery characteristics showed that the more pH increase, the more amount of adsorbed metal ion increase. Optimum adsorption time was 1 hr, and adsorption capacity was increased in order of $Cu^{2+}$<$Cd^{2+}$<$Pb^{2+}$, and recovery capacity was increased in order of $Cd^{2+}$<$Cu^{2+}$<$Pb^{2+}$.
