Bacterial cellulose (BC) has advantage such high purity. The alkali treatment and electrolysis process for bacterial cellulose leaving waste water. The objective of this research to investigate the precipitated solution as water waste of electrolysis. Through after treatment for water waste can be discovered the effect and product waste of electrolysis from bacterial cellulose. The after treatment was done by centrifuge and oven to get water waste become powder ready for characterization. From Fourier Transmittance Infra-Red result shows the characteristic of cellulose.

摘要

Bacterial cellulose (BC) has advantage such high purity. The alkali treatment and electrolysis process for bacterial cellulose leaving waste water. The objective of this research to investigate the precipitated solution as water waste of electrolysis. Through after treatment for water waste can be discovered the effect and product waste of electrolysis from bacterial cellulose. The after treatment was done by centrifuge and oven to get water waste become powder ready for characterization. From Fourier Transmittance Infra-Red result shows the characteristic of cellulose. The microcrystalline has peak at 3417 cm−1 as –OH stretching and 976 as β-Glycosidic bond. From X-Ray Diffraction result shows the powder has impurity and amorphous phase from bacterial cellulose. In XRD result showing the powder contain impurity exhibit peaks 2θ at 27.5°, 31.85° and 45.67° known as sodium chloride. This result showing electrolysis using sodium chloride can be two-step purification for bacterial cellulose. The precipitated solution contains amorphous phase of BC, the leftover of sodium chloride and other impurity.
