A grave predicament faced by humanity in the last century is the efficient
allocation of water resources, which is getting more degraded and polluted
due to the accelerating industrial activities. Data proves that about 80% of
wastewater effluents generated globally are dumped into the environment
without going through any treatment and increase up to 92% in impoverished
countries [WWAP, 2017]. Mentioned nuisances make the development of
competent and economical water treatment technologies inevitable for the
sustainable advancement of industry and society.
A group of atrocious substances that are frequently discharged into the
aquatic environment without proper degradation is phenolic substances,
which pose carcinogenic and pernicious properties for both marine organisms
as well as humans [Brandão, Y.B et al., 2017]. Unfortunately, numerous well-
established treatment techniques are revealed to be inadequate against
phenol because of factors including its high toxicity and generally formed
intermediate compounds [Tyagi M. et al, 2020].
An approach of water treatment that has accomplished to degrade a
great range of organic compounds, -including phenolic substances, - from
synthetic and industrial wastewater samples is the advanced oxidation
process (AOP), which comprises many diverse application techniques such
as Fenton and modified Fenton processes. This method is based on the
exceptional oxidizing power of free radicals, primarily HO• hydroxyl groups,
which can interact with any electron-rich substance, hence removing the
majority of the organic matter in the water. This feature of HO• radicals is
