Abstract

Phenol is considered as a hazardous agent in refinery waste water due to its toxicity to humans and animals. Therefore, numerous treatment processes are developed for removing this compound from industrial waste water which is an essential and important industrial need. In Baiji refinery-Iraq, the simulated produced wastewater with phenol concentration of 632 ppm represents a good example for examining a new application for removing this toxic agent. In this work, two different types of new heterogeneous catalyst were investigated and compared via catalytic wet photo oxidation process; namely, 5% ZnO/Al₂O₃ and 3% ZnO/Al₂O₃ as well as investigating temperature, reaction time, and mixing speed changes in photo baffled reactor. Results demonstrated that phenol removal efficiency proportional directly to reaction temperature, reaction duration, and mixing speed. A percentage of 95.45% Phenol removal was obtained using a temperature of 70 °C, reaction time of 100s, and a mixing speed of 750 rpm when using 5% ZnO/Al₂O₃. And when using 3% ZnO/Al₂O₃ the optimum removal was 86.22% with the same operating parameters. The new used technique proved to be a promising method for Phenol removal for industrial use in various applications.

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.
