| dc.description.abstract | Synthesis of sodium cellulose sulfate by sulfation reaction between cellulose
from paper and sulfuric acid. Preparation of paper samples was carried out without
treatment, washing using NaOH 2% and NaOCl 2%, and isolation with the addition
of HNO3 3.5%, NaOH 2% and Na2SO3 2%, NaOCl 1.75%, and H2O2 10%, the washing
paper produced cellulose of 19.8698 g (26.49% of the initial weight) while the isolated
paper produced cellulose of 12.6462 g (16.86% of the initial weight). Synthesis of
sodium cellulose sulfate through the sulfation reaction of paper cellulose with H2SO4
98% using ethanol solvent. The formation of sodium cellulose sulfate is supported by
FT-IR spectrophotometer which shows that in the wave number region 3391.0 cm-1
stretching vibration of -OH group, 2892.3 cm-1
is CH2 stretching vibration, 1212.1 cm1
S=O group and 996.4 cm-1 C-O-S group which is stretching and bending vibration
respectively. The sulfur content of sodium cellulose sulfate can determine its
substitution degree to determine the best sample preparation treatment.. The degree
of substitution values were 0.256; 0.77; and 1.21, respectively. SEM morphology
showed that the fiber surface of sodium cellulose sulfate was shorter than cellulose.
Particle Size Analyzer (PSA) test can determine the particle size of sodium cellulose
sulfate of 0,15244 μm. The electrical conductivity test shows that the highest current
strength is found in sodium cellulose sulfate from α-cellulose. | en_US |
