Titanium in Cement Determination with UV Vis

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
