Physicochemical Characteristics of Pineapple (Ananas mill.) Peel Cellulose Prepared by Different Methods

Abstract:

The physicochemical characteristics of pineapple peel cellulose prepared by three different methods were studied in this paper. SEM images showed a honeycomb-patterned structure on the surface of the cellulose prepared by fermentation and regenerated from [Amim]Cl and it showed compact feature on the surface of the one prepared by chemical method. FT-IR spectra analysis indicated they had similar chemical structure characteristic. XRD analysis results indicated typical cellulose I structural features of cellulose prepared by chemical method and fermentation while showing typical cellulose II structural features of cellulose by regenerated from [Amim]Cl. Futher analysis with TG and DTG confirmed that three cellulose all had characteristics of single fiber composition, but with different thermal decomposition phenomenon. It suggested that treatment with the ionic liquid [Amim]Cl could transformed crystal structure of pineapple peel cellulose from cellulose I to cellulose II. These findings may provide an approach on further utilization of pineapple peel cellulose.
