Solar purification and potabilization of water containing dyes

Solar purification and potabilization of water containing dyes Organic pollutant removal is the main field of water photocatalytic decontamination. Molecules such as pesticides (herbicides, insecticides, fungicides, etc.) or dyes are totally destroyed and mineralized into CO2 and innocuous inorganic anions (Cl−, SO 4 2− , NO 3 − ). Presently, two azo-dyes (i.e., containing the-N=N-azo group), Cibacron Brilliant Red 3B-A and Remazol Black B (Reactive Black 5), were successfully destroyed and totally mineralized. The stoichiometric coefficients of the total degradation, as well as the mass balances have been established with different analytical tools: TOC for carbon, DCO for oxygen, ionic-HPLC for heteroatoms (N, S, P) and pH-metry for hydrogen. Moreover, nitrogen balance has been established during the photocatalytic degradation of the dyes by considering not only nitrate and ammonium ions in the solution, but also the formation of N2 in the gas phase. The quantification of N2 molecules suggests that the photocatalytic degradation of azo-compounds is 100% selective in generating gaseous dinitrogen. The reaction mechanism was first determined in a laboratory photoreactor, before degradation in larger pilot solar photoreactors, using UV-A radiant flux from the sun in a new sub-discipline called heliophotocatalysis.
