چکیده
|
The chitosan was extracted from shrimp pandalus borrealis co-products,by the classic and hydrothermo-chemical technique. the products obtained were characterized by infrared spectroscopy (ftir). the results showed that the hydrothermo-chemical technique reduces the production time at least four times,and the chitosan has a higher deacetylation degree (60-85%) and yield (6-7% dry weight) than the classic process. the chitosan has shown an adsorption capacity around 40 mg/g for removal the dye reactive red 23 for the following condition: initial dye concentration 150 mg/l; contact time 3 hours; ph = 3. this paper sets out a possibility or the use of waste from the sea food industry,so reducing their environmental impact.
