Abstract
This study aims to synthesize and characterize chitosan beads using the Fourier Tranform Infra Red (FTIR) spectrophotometer. The test was carried out by making chitosan beads by mixing chitosan and 0.1 M acetic acid and dropping it into 0.1 M NaOH solution to form gel beads. Based on the results of the study obtained the value of the degree of deacetylation of chitosan by 76.85% and chitosan beads by 89.32%. While the characterization of chitosan beads based on FTIR spectrophotometer showed a difference in the peak absorption of NH3 at wave number 1450.47 cm−1 with a slightly wider band on the chitosan beads while the sharp NH2 absorption band appeared in the region of 1435.04 cm−1 in chitosan. And there is an absorption peak in the region of 570.93 cm−1 which is the KBR absorption peak used as pellets in chitosan samples.
