Catalysts of Cu(II) and Co(II) adsorbed in chitosan was used in transesterification of soy bean and babassu oils. The catalysts were characterized by infrared, atomic absorption and TG, and biodiesels was characterized by infrared, NMR, CG, TG, physic chemistry analysis. The maximum adsorption values found for copper and cobalt cations were 1.584 and 1.260 mg g(-1), respectively, in 180 min. However, conversion of oils in biodiesel was better when used Co(II) adsorbed in chitosan. (C) 2008 Published by Elsevier Ltd.
