Photocatalysis - Water purification - Performance of photocatalytic materials by measurement of phenol degradation
This document describes a test method to evaluate the performance of photocatalytic materials in water purification by measuring phenol degradation. This test method is applicable to photocatalytic materials in form of powders (suspensions in water, slurries) under UV irradiation. The photocatalytic performance of the tested material is assessed by the observed rate of phenol degradation at specified experimental conditions as determined by HPLC.
Photokatalyse - Wasserreinigung - Leistungsbewertung von photokatalytischen Werkstoffen durch Messung des Phenolabbaus
Dieses Dokument beschreibt ein Prüfverfahren zur Leistungsbewertung photokatalytischer Werkstoffe bei der Wasserreinigung durch Messung des Phenolabbaus. Das Prüfverfahren findet Anwendung bei photokatalytischen Werkstoffen in Form von Pulvern (Suspensionen in Wasser, Schlämme) bei UV Einstrahlung. Die photokatalytische Leistung des geprüften Werkstoffes wird durch die beobachtete Phenolabbaugeschwindigkeit unter festgelegten Versuchsbedingungen mittels HPLC beurteilt.
Photocatalyse - Purification de l'eau - Évaluation des performances des matériaux photocatalytiques par mesurage de la dégradation du phénol
Le présent document décrit une méthode d'essai permettant d’évaluer les performances des matériaux photocatalytiques dans le processus de purification de l'eau par mesurage de la dégradation du phénol. Cette méthode d'essai est applicable aux matériaux photocatalytiques sous forme de poudres (suspensions aqueuses, suspensions épaisses) soumis à une irradiation UV. La performance photocatalytique du matériau soumis à essai est évaluée par détermination en chromatographie en phase liquide à haute performance (CLHP) du taux de dégradation du phénol dans des conditions expérimentales spécifiées.
Fotokataliza - Čiščenje vode - Ugotavljanje zmogljivosti fotokatalitičnih materialov z merjenjem razgradnje fenola
Ta evropski standard opisuje preskusno metodo za ocenjevanje zmogljivosti fotokatalitičnih materialov pri čiščenju vode z merjenjem razgradnje fenola. Ta preskusna metoda se uporablja pri fotokatalitičnih materialih v obliki praškov (suspenzije v vodi, brozge), ki so obsevani z ultravijolično svetlobo. Fotokatalitična zmogljivost preskušenega materiala se oceni na podlagi ugotovljene stopnje degradacije pod določenimi preskusnimi pogoji, kot odloča HPLC.
