摘要：

Preparation, optimization and characterization of chitosan polymer from shrimp shellsBachir Ben Seghir, M. H. BenhamzaAbstract In this study, chitosan is extracted from shrimp Parapenaeus longirostris shells by a chemical process involving demineralization, deproteinization, decolorization and deacetylation. The effect of chitosan degree of deacetylation DD% is investigated using a model of response surface methodology (RSM). The using of ANOVA regression equation gives a determination coefficient R-2 = 0.9853, indicating the precision of the predicted model. Chitosan derived from chitin treated under optimized conditions of 28.6% of NaOH concentration, a temperature of 81.15 degrees C and a reaction time of 9.55 h, showed the highest value of DD% exceeding 98%. The obtained Chitosan characterization results using a spectral analysis infrared (FTIR), Differential Scanning Calorimetry (DSC), X-ray spectroscopy (DRX) and Scanning electron microscopy (SEM) confirmed the purity of chitosan.
