Abstract
Abstract: Removing toxic organic matter is one of the important tasks in
wastewater treatment. Recently, heterogeneous catalysts are used to activate
peroxymonosulfate and hydrogen peroxide in advanced oxidation processes
(AOP’s) based on sulfate radicals and hydroxyl radicals to remove these
substances. In this research, lanthanum perovskite catalysts with some
transition metals were prepared by citric acid sol-gel method and their
performance in advanced oxidation process of medicinal pollutant
ciprofloxacin was investigated using two oxidants, peroxymonosulfate and
hydrogen peroxide. It was found that the prepared catalysts had better
degradation performance in the presence of promonosulfate. According to
the results, the prepared LaCoO3 perovskite catalyst removes up to (71%) of
the peroxymonosulfate oxidant and up to (39%) of the medicinal pollutant with the hydrogen peroxide oxidant.
