10.6 Conclusion and Future Scope
The immense enthusiasm of the academic as well as industrial researchers towards
utilization of photo-oxidation techniques in wastewater treatment is reflected in the
increase in the critical number of publications over the past decades. The major
center of attention of this procedure is the hydroxyl radical, which nonselectively
attacks the pollutants present in waste water once created. However, a photocatalytic
(TiO 2 /UV) process, photolytic ozonation, a H 2 O 2 /UV process, and Fenton’s
responses have been considered and widely utilized for the removal of hard-headed
natural chemicals. Their treatment proficiency trusts upon different process parameters that have been thoroughly investigated. In order to develop a suitable method
for wastewater treatment, it is relevant to conduct experimental studies. There are
various factors that influence the reaction conditions such as initial concentration of
the target compounds, the amount of oxidation agents and catalysts, the light
intensity, the irradiation time, and the nature of the wastewater’s solution (pH, the
presence of solids, and other ions). The main challenge to address in the future could
be the development of proficient and minimal-effort materials to advance adequate
treatment, the utilization of sustainable power sources, the reception of systems for
forms reconciliation, and focusing on new classes of contaminants.
