Peroxymonosulfate Activation by MnO2/CoMoO4/NF for Degradation of Levofloxacin
MnO2/CoMoO4/ NF (Nickel foam) was obtained by loading MnO2 onto the surface of CoMoO4/NF using electrodeposition. The results of degradation experiments showed that the degradation efficiency of levofloxacin (LVF) (15 ppm, pH = 6.12) over MnO2/CoMoO4//NF reached 80.4% in 30 min when the PMS concentration was 0.08 mM. When the pH was lower or higher than the pH value of the original solution, the performance of the material significantly decreased due to the repulsive effect between the catalyst and SO52−. Cobalt and manganese ions exhibited a synergistic effect on the activation of PMS. The HCO3− ions showed the most significant inhibitory effect on the degradation of LVF. The free radical trapping experiments indicated that ·OH, and O2·− were the main active species in the degradation process of levofloxacin. The cyclic stability experiments proved the MnO2/CoMoO4/NF catalysts were efficient, stable and easy to recover.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
