Photocatalytic activity measurement, involves measuring transmission of similar measuring liquid that is provided in two identical measuring vessels, and calculating photonic efficiency from transmission changes of liquid

摘要

The process involves utilizing two identical measuring vessels with similar measuring liquid and with two uniform measuring samples. One of the samples is illuminated and other is shaded with a photocatalytic active coated surface. The transmission of liquids is measured, where different process of transmission is evaluated as photocatalytic effect. A photonic efficiency is calculated from transmission changes of the two liquids. An independent claim is also included for a device for measuring a photocatalytic activity using transmission measurement at coloring material solution.
