| 總結: | Starch and maltose are constructed chemically by glucose. Maltose can be produced by
starch hydrolisis. The objective of this research is to obtain a prospective membrane material
serving as membrane bioreactor. Separation of starch and maltose is a way to increase the
efficiency of enzymatic hidrolysis of starch to maltose. A great difference of size between
starch and maltose can be considered as a basis view of separation using microporous
membranes as filter. In this research, such a membrane was made by blending PMMA and
bentonite, with a ratio of 3:1, as supporting layer. The obtained membrane could separate
starch solution in feed with a percent rejection varying between 40 – 70%, while < 5% for
maltose. Composite membrane was prepared by interfacial polymerization of TMC and
MPD on PMMA – bentonite membrane as supporting layer. The performance of such a
membrane couldn’t be measured in this experiment. The obtained composite membrane
seemed to be very dense. Thus, there was no permeation of water, nor starch and maltose,
towards the membrane observed, for the operasional pressure applied (until 3 bar). |
