Pengembangan Membran Magnesol untuk Pemurnian Biodiesel

Abstract: Magnesol membrane has been prepared by mixing chitosan polymer with magnesol particles via  phase  inversion  method.  The  optimum  compositions  of  adsorptive  membranes  were  3% chitosan,  15%  DMF  and  60%  loading  adsorbent.  The  porosity  of  these  membranes  was 34,17% and swelling degree was 51,91%. The membrane clean water flux was 224,4 Lm^-2h^-1 at a transmembrane pressure of 2.5 bar.  The adsorptive membrane possesses an open and interconnected  porous  structure  with  a  large  surface  area  available  for  biodiesel  purities adsorption. The results showed that after contacting in 60 minutes, numbers of acid value was reduced  as  81,12%  which  is in  accordance  with  value  of  SNI  quality  standards.  In  addition, the soap content adsorbed was 86,74%  as potassium soap and 86,73% as sodium soap. The regenerated  membrane  can  be  reused  with  mantaining  the  high  adsorption  capacity.  The methanol  was  better  than  ethanol  to  regenerate  the  magnesol  membrane.  The Magnesol membrane will be a new alternative method for biodiesel purification.
