摘要: Abstract The degradation of different copolymers acrylamide and acrylic acid by Fenton's reagent was studied. polymers tested were either homopolymers or containing lignin sulfonate, guaiacol 3,4-dihydroxylbenzoic acid, respectively. Acrylamide (PAAm) degraded faster than (PAA). Among the PAAm, sulfonate at a significantly higher rate corresponding homopolymer, whereas among PAA, highest with acid. decrease H 2 O , i.e. hydroxyl radical production in presence certain polymer, did not correlate its degradation. It concluded that incorporation phenolic compounds into an chain may accelerate decay these wood decaying fungi, which reportedly produce radicals extra-cellularly, through use advanced oxidation systems applied sewage cleaning.
