ACID BLUE 80 CAS 4474-24-2

Acid Blue 80 is a blue powder that is highly soluble in water. Its aqueous solution is deep blue, and when hydrochloric acid or sodium hydroxide is added, it turns magenta. The dye appears red-blue in concentrated sulfuric acid and turns greenish-blue after dilution. It appears brown in concentrated nitric acid. Acid Blue 80 is a typical dye with refractory anthraquinone functional groups. Currently, its dye wastewater is usually treated by activated carbon method, aerobic and anaerobic biological methods. The Acid Blue 80 index (" ABI ") is a relative measure of the amount of acid blue 80 adsorbed by carbon materials from standard solutions.
