Discover how ozone is detected in water using a compact electro-chemical cell.
A clearly explained method shows how a small cell, formed by a platinum rod inside a copper tube, measures ozone by the current it generates as water flows between the electrodes. When oxidising agents are present, the cell depolarises and the current rises, allowing precise monitoring of ozone levels. The setup is described with practical flow rates, electrical readings, and the sensitivity needed to detect very small amounts of ozone in water.
This edition clarifies the relationship between ozone concentration, electrode reactions, and the resulting electrical signals. It also explains why only part of the ozone contributes to the depolarising current and how real-world water composition affects operation. The text presents the science in accessible terms and includes observations on yield, efficiency, and the limits of detection.
- Learn the basic design of the ozone-detecting cell and how it converts chemical changes into a current
- See how water flow rate and solution chemistry influence measurements
- Understand the factors that limit sensitivity and accuracy in practical use
- Grasp the practical relationship between ozone concentration and the device’s response
Ideal for readers interested in early electrochemical methods for gas detection and the historical development of ozone measurement.
