Abstract
The potential application of methemoglobin from bovine blood to remove aromatic compounds in the presence of hydrogen
peroxide has been evaluated. The organic compounds herein tested include phenols, amines or hydrocarbons, which are
pollutants deriving from different industries and display high persistence and toxicity in waters. The oxidative process has been
characterized by soluble hemoglobin and immobilized on Eupergit CM, using 4-chlorophenol as a model substrate. The
obtained data revealed the good effectiveness of the biocatalytic process within the pH 6-8 range, with an optimum pH of 7.5 for
the free protein and of 7.0 for the immobilized one. Oxygen evolution in the system was also measured continuously, and
indicated that this system significantly contributes to reduce oxygen demand in wastewaters. It was possible to reuse the same
hemoglobin-polymer beads as biocatalysts three times. Therefore, the use of hemoglobin in industrial wastewaters treatment may
be a good alternative because, despite being somewhat less active, it is able to catalyze the oxidation of different aromatic
pollutants, is relatively cheap, and is a food industry waste, which makes the process more ecofriendly.
