| dc.description.abstract | The study is aimed to synthesis chitosan membrane from shrim shell waste and
modification of membrane by additing natural nanozeolite Sanilla by varying the
composition of nanozeolite toward the membrane performance. The membrane obtained
is determined Flux and selectivity on the separation of ethanol-water mixture by
pervaporation. The chitosan used has a degree of deacetylation of 84. 7% and natural
nanozeolite Sarulla (@ZAS) used has a @ZAS aktivated at 400°C for 4 hours and data
XRD data showec! that the zeolite which usd to resemble modemit. The result of SEM
showed that the membrane surface is relatively smooth, homogeneous and fine pores
evenly dispersed, while the Ch-@ZAS membrane surface looks uneven, heterogeneous
and rough surface due the zeolite dispersed. These results are supported by IR data
which showed the occurrence of mixing physical and chemical interactions between
chitosan and @ZAS. The swelling and performance (flux and selectivity) of membrane
generally increases with the addition of @ZAS composition to the chitosan matrix. The
optimum composition membrane obtained addition of 0.30 g @ZAS (membrane Ch@
ZAS_ 4). The laboratorium Scala tests showed that the nano composite membrane
chitosan natural zeolite Sanilla, which is synthesized at optimum composition, with the
feed ethanol at composition of 98% w/w and 65°C, has the highest fermentation flux of
water and totality were 0.98 Kg/m2 hour and 1.05 Kg/m2 hour respectively, while the
highest selectivity was 1168. This study has also able to increase the concentration of
ethanol to 99.22% (w/w). | en_US |
