Abstract
The management of environmental analysis waste through Fenton-based advanced oxidation processes is proposed. Degradation of dyes as methylene blue (MB) and methyl red (MR) is obtained in presence of iron(II)-complex and hydrogen peroxide at mildly pH conditions with no formation of sludge. The role of temperature and UV-A are discussed.
Highlights
Most dyes used in industry produce effluents that are not satisfactorily treated by conventional biological wastewater processes[1]
Advanced oxidation processes (AOPs), as those based on Fenton reaction, have been successfully used for this purpose, but there are some drawbacks as low operational pH and sludge formation[3]
Temperature and UV-A present a synergistic effect in the process
Summary
Most dyes used in industry produce effluents that are not satisfactorily treated by conventional biological wastewater processes[1].
