removal from the wastewater before discharging them within the environment. So far, low comprehensive studies have been conducted for determination and removal of phthalates from the aqueous environment, including
adsorption by graphene oxide 8, Activated sludge use extended aeration 9, 10, chlorination 11,12 have been used to removal of phthalates.Each of the water treatment processes has a number of disadvantages, including operating and maintenance cost, inefficiency, long reaction time, sludge production, and the need to manage sludge production 13. The most important problem with the above processes is to transfer pollutants from one phase to another phase without degradation or decomposition of contaminants. Today, advanced oxidation processes (AOPs) have received considerable attention to decompose toxic and non-degradable pollutants which can produce radical hydroxyl (
•OH) under conditions of ambient pressure and temperature conditions
1, 14.
After radical fluorine, which is the strongest oxidant agent, Radical hydroxyl (
•OH) is ranked second.
•OH attacked the organic compounds in the liquid phase and degraded it and finally converted organic compounds into mineralization, decomposition, degradation and harmless forms such as CO
2 and H
2O. Some of the processes that produce hydroxyl radicals including catalysts
15, 16. UV/H
2O
2 17, O
3 18, UV/O
3 19, Fenton
20, Electro Fenton
21, ultrasonic waves
21, 22, and combination oxidation process are the most common class of AOPs. Advanced oxidation processes can be used as an effective technique to remove phthalates and other EPs. In addition to a treatment process that reduces and eliminate pollutants, appropriate use of products and replacing these materials with those that are environmentally friendly can be an approach to prevent the release of these ECs to the environment.
