BS EN 17120:2019

This standard BS EN 17120:2019 Photocatalysis. Water purification. Performance of photocatalytic materials by measurement of phenol degradation is classified in these ICS categories:

• 25.220.20 Surface treatment

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.
