In this work, hydrogel of polyacrylamide (PAAm) was obtained by free radical polymerization of acrylamide (AAm) in the presence of N,N¡¯-methylenebisacry1amide (MBAAm), in aqueous media. The hydrogels were cut and dried before to be used in saturated fuels. Saturated blends of biodiesel and diesel were mixed in appropriate amounts to form B0 (0 % biodiesel and 100 % diesel by volume), B20, B40, B60 and B100. A large study was done to synthesize an absorbing material to have appropriated characteristics to be used as water absorbing of fuel samples. The most suitable material must present high swelling ratio combined with an enough density of cross-linked structure that enables handling the material. The dried hydrogels were added to the saturated biodiesel, diesel and blends. The results showed that, for saturated diesel (B0), the water content was reduced down to 85 ppm from 220 ppm (reduction of 60 % of water content). The reductions of water content for B20, B40 and B60 were 58, 57 and 64 % , respectively, after 240 min of treatment with hydrogel.
