Photocatalytic Degradation of Emergents Pollutants in Nanoparticles Solution

Among different advanced oxidation processes (AOPs), heterogeneous photocatalysis has emerged as a promising process of water treatment. Its effectiveness results from an oxidation by radicalizing way initiated by the attack of a very reactive radicalizing entity generated in the medium (the radical hydroxyl, HO.). This work aims to study the effectiveness of heterogeneous photocatalysis in water treatment containing emerging pollutants. The experiments were carried out in an aqueous suspension of titanium dioxide and zinc oxide with the use of the sun such as natural radiation. The comparative study between the two catalysis indicates that the degradation of paracetamol is very effective with zinc oxide.
