Characterization of α-Cellulose from Bagasse Cane Bz 132 (Saccharum officinarum)

Abstract

: A study concerning the separation of α - cellulose from bagasse were conducted using Okhamafe. The first stage is the preparation of bagasse powder type Bz 132. Stage second is the separation of α - cellulose from bagasse is done with the method Okhamafe done by immersion in 3.5 % HNO acid, bleaching with Sodium Hypochlorite 1.75 % and purification with 17.5 % NaOH. The third stage is the characterization of α cellulose from bagasse types Bz 132 showed visible surface with large round -shaped grains are almost the same size (uniform). This may indicate that the resulting α - cellulose has a form of homogeneous size (as large). From the analysis of functional groups with the free OH groups visible wave number 4001.50 cm-1 which shows a typical chain of cellulose CH2OH and OH hydrogen bonds with wave number 3437.30 cm-1 as supporting data. Of the thermal test with test results obtained DTA melting point at a temperature of 60oC and 320oC decomposition point.
