Hanna Instruments HI-3864 Phenols test kit
Phenols are important starting materials in chemical and pharmaceutical industries. They are widely used as colouring agents, indicators and disinfectants.
The HI-3864 phenols test kit presents a simple way to perform an accurate chemical analysis.
This test kit for phenols determines the phenol concentration in water via checker disc. Phenolic compounds react to form a yellow to orange dye with 4-amino antipyrine in alkaline solution buffered at pH about 10. The absorbance of this coloured product is proportional to the concentration of phenols present in the aqueous sample.
