Abstract

By constructing catalytic membranes, the tedious post-treatment catalyst separation during the utilization of powdered catalysts can be avoided. In this work, a copper ferrous disulfide catalytic membrane (CuFeS₂-M) prepared by in-situ loading CuFeS₂ on a ceramic tubular membrane was employed to activate sodium percarbonate (SPC) towards the degradation of organic dye pollutants. Under the optimum conditions (SPC dosage of 8.0 mM and flow rate of 1.0 mL/min), the removal efficiency of 10 mg/L acid orange 7 (AO7) achieved 97.93%, and several other organic dyes were also efficiently removed by 75.23–95.96%. The coexisting inorganic anions and humic acid showed little detrimental effect on the removal of AO7. Reusability tests showed that CuFeS₂-M could effectively catalyze the degradation of AO7, removing around 7 mg of AO7 during the operation time of 12 h from both deionized water and synthetic wastewater. Furthermore, the degradation mechanism analysis revealed that CO₃^•− was the main reactive oxidative species. Finally, the degradation pathway of AO7 was investigated, and the environmental toxicity effects of the degradation products were also predicted. Therefore, the CuFeS₂-M/SPC system exhibited prospective application for the oxidative removal of AO7 and other organic dyes from water.

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.
