dc.description.abstractacid and alkali concentrations. A three level factorial design of experiment with alkali andacid concentrations was used. FTIR, XRD and SEM were used to investigate the structural changes aftertreatments. Results reveal that both alkali and acid concentrations significantly affect the development ofthe functional groups and their intensities in the extracted chitin. A certain combination of concentrationof acid and alkali can be used to obtain chitin with high degree of order (Crystallinity Index (CrI) > 0.9)and a degree of de-acetylation (DD > 50%). This results in combined high crystallinity and degree of de-acetylation. The study also established that certain combination of acid and alkali concentrations couldlead to alpha to beta transformation in chitin structure.© 2017 Elsevier B.V. All rights reserved.1.
