Protonation of azobenzene derivatives. I. Methyl orange and ortho -methyl orange

open access: yesAustralian Journal of Chemistry, 1973
Thermodynamic acidity constants have been measured over the temperature range 5-50° for aqueous solutions of sodium 4?-dimethylaminoazobenzene- 4-sulphonate (methyl orange) and sodium 4?-dimethylaminoazobenzene-2- sulphonate (ortho-methyl orange). From these data values of the standard enthalpy, entropy, and heat capacity changes have been calculated ...

THE ADSORPTION OF METHYL ORANGE BY LYSOZYME

open access: yesCanadian Journal of Biochemistry and Physiology, 1954
Adsorption isotherms for methyl orange on lysozyme at ionic strengths varying from 0.001 to 0.05, pH 5.5, are sigmoid. Increasing ionic strength shifts the inflection point of such isotherms to higher free anion concentrations. Binding of one methyl orange anion to a lysozyme molecule in 0.05 M acetate, pH 5.5, facilitates adsorption of nine others ...

Radiation-induced degradation of methyl orange in aqueous solutions

Chemosphere, 2008
Degradation of methyl orange under gamma-irradiation was investigated. The reactions followed pseudo first-order kinetics. Apparent degradation rate constant, estimated through linear regression analysis, increased with an increase of dose rate and a decrease of initial methyl orange concentration.
