Résumé:
This work is to implement a new reactor glidarc third generation. This device can generate plasma of humid air in order to treat liquid flowing into falling film. The reactor treats liquids in continuous flow and gravity, two characteristics highly recommended by manufacturers. Optimizing glidarc III inevitably the treatment of distilled water and analyzing the plasma-concentration of different species. The right approach is to vary the flow of plasma gas, electrode-film distance and velocity. The impact of plasma on the target is large and massive.
The results showed that the aqueous solutions of dyes lend themselves effectively to treatment with the new reactor.
In the case of the molecule under study it was shown that the rate of mineralization by Fenton process (Fe2 +/ H2O2) is a function of doses of reagents used and the initial concentration of AG 25.
A performance comparison of different digestion methods studied (Plasma/Fenton Plasma/H2O2, Plasma/Fe2 +, Fenton out plasma and plasma) showed that the plasma / Fenton is to achieve a very high rate of mineralization (≈ 96% after 90 min).
