Influence of hydrogen peroxide on the degradation of anthelmintics in wastewater

Antiparasitics are among the new water pollutants, given that their potential negative impact on the environment has recently been highlighted. By secretions of animals and humans, they can easily reach the soil and water where they have negative impact on other organisms. Also, the presence of microplastics in water is a growing problem with confirmed negative effect on human and animal health. Microplastics are smaller than 5 nm in size and have an extremely heterogeneous composition, which makes its effective elimination from water a great challenge and frequent subject of research. In this research, using HPLC equipment, the composition of degradation products according to the similarities of the absorption spectrum was analysed for the antiparasitic febantel. Degradation of antiparasitic was attempted by mechanical mixing in the presence of hydrogen peroxide. Solar radiation was also simulated in order to research the possibility of antiparasitics degradation by the action of photons. These simulated conditions were also examined in the presence of microplastics to monitor its possible impact on degradation. The results showed different percentage degradation. The amount of degradation products varies depending on the pH value and concentration of hydrogen peroxide.
