Description

Methyl orange is a dye that is used as an indicator in acid-base titrations. It has a basic structure and can be prepared by the oxidation of para-aminobenzoic acid with hydrogen peroxide. Methyl orange has been shown to exhibit synergistic effects with other antimicrobial agents, such as phenol, methylene blue, and chlorhexidine at pH levels of 4.5 to 7.0. The optimum concentration for the matrix effect is 0.01% at pH range from 2.5 to 4.5 and 1% at pH range from 5 to 7.5. Methyl orange is activated by light with wavelengths between 300 nm and 500 nm and can be used in wastewater treatment processes where there are high levels of organic matter or radiation, such as carthamus tinctorius or zirconium oxide.
