“…The peaks at 1346 cm −1 and 1500 cm −1 were disappeared in the microwave treated sample, indicating that lignin was removed. This is in agreement with Abral, 2014 [19] and Sundari, 2012 [20]. These observations indicate that microwave treatment removed lignin leading to expelling of cellulose and hemicellulose from tight matrices.…”

“…5 shows FTIR spectra of the untreated water hyacinth and the treated samples. The peaks were observed at 1240 and 1346 cm −1 are those of C−O stretching of syringyl lignin and C−O−C of hemicellulose oscillation in anomeric region [19]. The peak at 1500 cm −1 indicates the CC stretching of aromatic rings of lignin [20].…”

Abstract-The effects of three physical pretreatment methods (water bath, ultrasound and microwave) on the cellulose recovery of water hyacinth were investigated in this study. Before treatment, cellulose and hemicellulose content of dried water hyacinth sample was 36.04%. After treating by ultrasound (70 o C for 1 h) at a ratio of deionized water (DIW) (mL) to dried sample (g) of 10:1, cellulose and hemicellulose content in the treated sample was 57.70.65 %. The highest yield of cellulose and hemicellulose (58.190.59%) obtained by water bath treament at 100 o C for 1 h whereas the cellulose and hemicellulose yield was 60.420.07% attained by microwave pretreatment (350W, 10 min at a ratio of DIW (mL) to dried sample (g) of 10:1). Therefore, among three pretreatment methods, microwave assisted DIW pretreatment presented the best efficiency on cellulose recovery. The outcome showed that microwave assisted DIW pretreated water hyacinth is a promising raw material for bioethanol production. The effects of these treatments on the composition and structure of water hyacinth were studied by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).Index Terms-Water hyacinth, Eichhornia crassipes, cellulose recovery, ultrasound, microwave and water bath.

A B S T R A C TThis article reports effect of vibration duration of high ultrasound applied to bio-composite while gelatinized on its properties. The bio-composite consists of mixing of both the tapioca starch based bioplastic and oil palm empty fruit bunch (OPEFB) fibers with high volume fraction. Gelatinization of the bio-composite sample was poured into a rectangular glass mold placed then in an ultrasonic bath with 40 kHz, and 250 watt in different duration for 0, 15, 30, 60 min respectively. The results show that vibration during gelatinization has changed the characterisation of the bio-composite. SEM photograph displayed different fracture surface of tensile sample. For vibration duration of 60 min, tensile strength (TM), and tensile modulus (TM) was improved to 64.4, 277.4%, respectively, meanwhile strain was decreased to 35.1% in comparison without vibration. Fourier Transform Infrared Spectroscopy (FTIR), and XRD diffraction of the bio-composite has changed due to various vibration duration. Moisture absorption of the vibrated bio-composite was lower than that of the untreated one.
