The paper presents the obtaining, characterization and testing of a new type of polyelectrolyte based on acrylamide, acrylic acid and sodium alginate for flocculation purposes. Two types of monomeric solutions were irradiated at room temperature and in atmospheric conditions with doses between 0.5 and 2 kGy using the ALID 7 electron accelerator of 5.5 MeV. The flocculants were characterized in order to determine conversion coefficient, residual monomer content, intrinsic viscosity, molecular weight and radius of gyration. The flocculation characteristics were evaluated in 0.1 and 0.2 wt% blue kaolin suspension at room temperature.
