초록
게 껍질과 갑오징어 널에서 조제한 키틴과 키토산을 흡착제로 사용하여 염색공장에서 폐기되는 폐색소를 정화하기 위한 실험을 수행하였다. 이중 키토산이 키틴 보다 효율적인 흡착제로 작용하였으며, 키토산을 채운 컬럼 실험에서 1kg의 키토산은 0.05%의 색소를 함유한 염색 폐수 120L를 75% 효율로 흡착제거하였다. 이는 1kg의 키토산이 45g의 색소를 흡착하였다는 것을 의미한다.
Chitin and chitosan from red crab and squid pen were applied as adsorbents for trapping the dyes in wastewater from dyeworks. We found that the chitin and chitosan were effective adsorbents for the dyes discarded from dyeworks. Chitosan was more effective in dye adsorption than chitin. In a continuous elution column experiment, 1 kg of chitosan could be used for treatment of upto 120 L of wastewater containing 0.05% dye wasted from dyeworks at 75% efficacy, that means 45g dye was adsorbed per kg chitosan.
