1,10-Phenanthroline hydrate CAS 5144-89-8

Phenanthroline (phenanthroline) is a commonly used redox indicator. As a simple, low-cost and fast analysis method, phenanthroline colorimetry is widely used in iron. in the detection analysis. The principle is that phenanthroline and Fe2+ will form a stable orange-red complex in the solution of pH=3～9, and the color depth of the complex can be used to determine the content of iron ions in the sample to be tested. Although this method is highly sensitive, it is still affected by other components in the sample. When using this method to determine the content of substances, it is necessary to pay attention to the experimental conditions such as the amount of phenanthroline, the pH environment, the time required for the reaction and the wavelength.
