CONTRIBUTION TO THE WATER DISINFECTION BY PHOTOSENSITIZATION WITH PLANT EXTRACTS
2019
The study of water disinfection by photosensitization with methoxy-5 psoralen showed complete inhibition of fecal coliforms after 60 minutes of exposure to the light at all concentrations used (0.006; 0.2 and 0.340 g / l). The kinetic study shows that the kinetic constants are classified in the following order: 0.11; 0.15 and 0.17 min-1, respectively for 0.006; 0.2 and 0.340 g / l. In the other hand, for the faecal enterococci, complete inhibition was observed after 5 minutes of exposure at all concentrations used (0.006; 0.2 and 0.340 g / l).
