Description

C.I.Acid Yellow 42 is a reactive dye that belongs to the class of chromatic compounds. It is used in photolithography and as a pH indicator, but is also an environmental pollutant. C.I.Acid Yellow 42 is hydrated and has radical mechanism of photodecomposition, which makes it subject to radiation and mineralization. C.I.Acid Yellow 42 can be used in assays for detecting ions such as copper, iron, zinc, or mercury at efficiencies greater than other dyes in the same class. It can also be synthesized from organic materials or biodegradable substances such as dyes from natural sources or phenol-formaldehyde resins with low toxicity to humans and the environment.>>END>>
