ASSESMENT OF THE CATALYTIC PROPERTIES OF CoFe2O4 IN THE OXIDATION REACTION OF THE METHYLENE ORANGE

The sample of cobalt ferrite nanopowder synthesized by spray pyrolysis was studied with respect to catalytic activity in a model oxidation reaction of methylene orange with hydrogen peroxide. It was established that in the presence of a catalyst, the reaction rate with the addition of a CoFe2O4 catalyst in the first 15 minutes exceeded the reaction rate without the addition of a catalyst by 17 times. It is shown that the oxidation efficiency of the methylene orange dye in the presence of a cobalt ferrite catalyst is 83,09%, which is 2,75 times more than the oxidation efficiency in the absence of a catalyst.
