Title
(EN) SYSTEM FOR DEGRADING CHEMICAL CONTAMINANTS IN WATER
(FR) SYSTÈME DE DÉGRADATION DE CONTAMINANTS CHIMIQUES DANS L'EAU
Abstract
(EN)
A system for degrading contaminants may include a reactor containing a boron nitride photocatalyst. The reactor system may be configured to receive an aqueous liquid comprising at least one contaminant, and may also include a light source configured to direct light to the boron nitride photocatalyst, and an oxidant source in fluid communication with the reactor.
(FR)
Un système de dégradation de contaminants peut comprendre un réacteur contenant un photocatalyseur au nitrure de bore. Le système de réacteur peut être configuré pour recevoir un liquide aqueux comprenant au moins un contaminant, et peut également comprendre une source de lumière configurée pour diriger la lumière vers le photocatalyseur au nitrure de bore, et une source d'oxydant en communication fluidique avec le réacteur.
