This application note provides a method to determine the TiO2 content in cement. TiO2 forms a yellow color complex with hydrogen peroxide. Absorbance of this colored complex can be determined at 410 nm using a
UV-Vis spectrophotometer.
Background
With increasing air pollutants, the demand for self-cleaning building materials has become more relevant in recent years. Titanium oxide (TiO2) is used to make self-cleaning cement. TiO2 content in the cement breaks down the pollutants; for example, it reduces NOx levels.
This application note includes:
- An introduction to the topic
- A list of instruments and accessories
- An explanation of the method in detail
- Results and remarks
