Usage

General Description

Semixylenol orange is a chemical compound commonly used in the determination of metal ions, particularly aluminum and iron, in water and biological samples. It is a selective chelating reagent that forms stable complexes with these metal ions, resulting in a colorimetric response that allows for their quantitative detection. In the presence of aluminum and iron, semixylenol orange produces a pink to red color, which can be measured spectrophotometrically. Its high selectivity for these metal ions makes it a valuable tool in environmental and analytical chemistry for the monitoring and analysis of metal ion concentrations in various samples.
