Abstract

Chitosan-cellulose composite beads had been prepared using cellulose isolated from sugarcane bagasse. Sugarcane bagasse was hydrolyzed with H2SO4 with various concentrations (30, 40, and 50%). Cellulose obtained was characterized using Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). FTIR analysis results inform the existence of typical functional groups of cellulose in the sample. XRD patterns show H2SO4 concentration on the hydrolysis process influence the crystallinity of cellulose. Cellulose was used as a filler in the preparation of chitosan-cellulose composite beads. The results show that cellulose decrease the crystallinity of chitosan.

Highlights

Sugarcane bagasse is still considered as an invaluable waste which contains cellulose (38.9%) [1]
In order to increase the economic value of sugarcane bagasse, in this work we used cellulose isolated from sugarcane bagasse as a filler of chitosan polymer
X-Ray Diffraction (XRD) pattern of sugarcane bagasse shows lower intensity and broader peaks than XRD patterns of cellulose isolated from sugarcane bagasse with various concentration of H2SO4

Summary

INTRODUCTION

Sugarcane bagasse is still considered as an invaluable waste which contains cellulose (38.9%) [1]. The use of sugarcane bagasse as a source of cellulose has not been widely reported. Cellulose extraction through hydrolysis with strong acid is the most common used method [2,4]. Modification of chitosan using cellulose is expected to produce a new material that has better properties than its nature. The formation of a new material of chitosan-cellulose composite is expected to be used as an adsorbent which can improve the weaknesses of each material. Some researchers have reported the preparation of chitosancellulose composite They used commercial cellulose which produced expensive composite. It is known that sugarcane bagasse contains cellulose. In this work we used cellulose from sugarcane bagasse for chitosan-cellulose composite beads preparation
