Abstract

This research aims to develop cellulose products extracted from corn stalk to use as cellulose beads. Cellulose has extracted using the best solvent, which is 10% NaOH. The extracted cellulose was modified to carboxymethyl cellulose using a monochloro acetate reagent with the best ratio of 5:5 and 3 hours of reaction time. Cellulose beads made from carboxymethyl cellulose and alginate with the best composition 1: 2. This study uses variations of BaCl2 crosslink 3%, 5%, and 10%. Fourier Transform Infra-Red (FTIR) characterization to determine functional groups of beads. Then geometry analysis of beads using optical microscopy, and surface morphological analysis using X-ray Scanning Electron Microscopy-Energy (SEM-EDX). The best cellulose beads are base on high swelling 97.1% at 5% crosslink concentration.
