Abstract
|

|
|
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 ㎏ 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 45 g dye was adsorbed per ㎏ chitosan.
