초록

식품가공 공장에서 1차 가공되고 버려지는 게껍질을 화학처리하여 chitin을 제조한 후. 탈아세틸화하여 chitosan(Cs)을 제조하여 이 chitosan에 acrylic acid, maleic acid, fumalic acid를 그라프트공중합시켜 CsAa, CsMa와 CsFa를 합성하였다. Cs, CsAa, CsMa와 CsFa의 구조 확인은 FT-IR, 전자현미경, X-Ray회절분석기로 하였으며, 응집제로서의 가능성을 검토하기 위하여 제지공장 폐수를 대상으로 응집제의 투입량을 변화시켜 본 결과 투과도, COD, SS의 제거율이 투입량 40ppm에서 제일 좋았으며, chitosan 보다 그라프트중합체를 사용했을 때의 제거율이 월등히 개선되었다. pH 변화에 따라서는 투과도, COD, SS의 제거율이 pH 5에서 가장 우수한 결과를 나타내었다. Chitosan 보다 그라프트공중합체인 CsAa, CsFa와 CsMa가 월등히 우수한 제거율을 나타내고 있는 것은 chitosan에 카르복시기를 가진 단량체가 공중합됨으로서 양쪽성을 띠기 때문으로 예측된다.

By grafting acrylic acid, fumalic acid and maleic acid onto chitosan, graft copolymers, CsAa, CsFa and CsMa, respectively were prepared for potential uses as flocculants in waste water treatment. When 40 ppm of each grafted chitosan sample was added into the waste water, CsMa showed the best removal rate of COD and suspended solids(SS), followed by CsFa and CsAa and chitosan. The transmittance and removal rate of COD and SS were the highest at pH 5. All grafted chitosan exhibited better performance than chitosan itself, resulting from the amphiphilic property of grafted chitosan copolymer with carboxy groups.
