PREPARATION AND CHARACTERIZATION OF CELLULOSE NANOFIBRES FROM PINEAPPLE LEAF FIBRES AND SUGARCANE BAGASSE
Abstract
- The aim of the study was to extract cellulose nanofibres (CNF) from pineapple leaf fibres (PALF) and sugarcane bagasse (SCB). The CNF was isolated from PALF and SCB by mechanical treatments and chemical treatments using alkaline, acids and inorganic salts. The physicochemical properties of prepared samples such as moisture content, ash content, pH and solubility were determined conventionally. Yield percent of pineapple leaf cellulose nanofibres (PALCNF) was higher than that of sugarcane bagasse cellulose nanofibres (SCBCNF). The raw samples and prepared samples were characterized by XRD, FT IR, EDXRF and SEM analysis to confirm as cellulose nanofibres. Crystallinity index percent of the prepared cellulose nanofibres was investigated by using XRD analysis. According to the XRD investigation, PALCNF and SCBCNF have the sharp diffraction peak is 2 value at 22˚ and the amorphous diffraction peak is 2 value at 18˚. It could be noticed that cellulose was present in the form of cellulose. Based on the FT IR spectrum, there are several peaks in raw samples which are not found in the spectrum of cellulose nanofibres. The EDXRF table shows the elemental constituents of the untreated raw samples and the CNF after chemical treatment. The SEM analysis showed that the PALCNF has fibrous nature and the SCBCNF has irregular aggregated shape fibrils.
