Definition
Micropollutants are water pollutants with the maximum concentrations as high as few micrograms/liter and the minimum concentrations as low as few nanograms/liter of water. Micropollutants typically enter water streams as a result of human activity.
Advanced oxidation processes are water purification technologies which involve generation of strong oxidizing species that destroy pollutants.
Photocatalysis is light-activated acceleration of chemical reactions in the presence of a light-absorbing photocatalyst material.
Heterogeneous photocatalysis uses a light-absorbing solid photocatalyst to produce oxidizing and reducing species in the presence of light. Heterogeneous photocatalysis is one of the advanced oxidation technologies for water treatment, which uses strong oxidizing species to degrade organic pollutants.
Introduction
The demand for clean water is rapidly increasing worldwide, as the global population is growing. The United Nations (UN) recognized access to clean...
