摘要: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.
