A Potency of Microcellulose from Pineapple Leave Isolated by Hydrolysis-Assisted Sonication

Abstract

Abstract Cellulose has been reported have many functions for separation and adsorption of heavy metals and organic materials waste or pollutants. This paper reported the preparation of micro size cellulose from the waste of pineapple leaves. The strategy involves delignification, bleaching, and hydrolysis process. The hydrolysis step plays an important role for cutting of the cellulose chain, and ultrasonication assisted hydrolytic procedure was applied. In addition, the isolated product was characterized by means of FTIR spectrometry to identify functional group, Scanning Electron Microscopy to inform morphology features, and Particle Size Analyzer to inform the size of cellulose particle. The yield of initial isolated cellulose was 62.07%. Then, through the ultrasonication process using 30% of sulphuric acid for 1 hour at room temperature resulted about 3.497% yield of microcellulose. The FTIR show O-H, C-O-specific band for cellulose in 3402 cm−1, 1385 and 1200-1300 cm−1, respectively. This finding lead for further application of this micro/nano-cellulose for heavy-metals-and dye pollutants adsorbent.
