Decolorization of methyl orange by ozonation in combination with ultrasonic irradiation
Journal of Hazardous Materials, 2006The combination of ultrasound and ozone for the decolorization of azo dye, methyl orange, was studied. The effect of ultrasonic power, ozone gas flow rate, gaseous ozone concentration, initial dye concentration, pH and hydroxyl radical scavenger on the decolorization of methyl orange was investigated.

The demethylation of m-methyl orange and methyl orange in vivo and in vitro
Biochemical Pharmacology, 1966Abstract Rats given m -methyl orange and methyl orange intraperitoneally and intravenously excrete the monomethylated and completely demethylated dyes in urine and in bile. Mouse liver microsomes also demethylate methyl orange. The results indicate that factors other than lipid solubility are important in the microsomal metabolism of drugs.

Biphoton holographic storage in Methyl Orange and Ethyl Orange dyes
Optics Letters, 1994Biphoton holograms are recorded by a He-Ne laser in Methyl Orange and Ethyl Orange dyes on exposure to a 514.5-nm argon-ion laser, and the dynamic of holographic recording is reported. The recording utilizes an unusual photochemistry that is due to either to a triplet-triplet transition from a long-lived triplet lower state of the cis configuration or ...

Protonation of azobenzene derivatives. I. Methyl orange and ortho -methyl orange
Australian Journal of Chemistry, 1973Thermodynamic 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 reaction of methyl orange with bromine
Analytica Chimica Acta, 1973Abstract The kinetics of the reaction between bromine and methyl orange have been studied in bromide medium and at perchloric acid concentrations of 0.3–0.9 M. A rate equation has been derived and a mechanism is proposed which is in agreement with the experimental results.

Adsorption of Methyl Orange on Starches
Journal of Food Science, 1991ABSTRACT Adsorption characteristics of methyl orange were investigated on kudzu, sweet potato, corn, rice, wheat, potato and snake gourd starches. No adsorption of methyl orange, an anionic dye, was observed on potato starch and snake gourd starch because of the presence of phosphate esters. Adsorption isotherms were found to fit both

THE ADSORPTION OF METHYL ORANGE BY LYSOZYME
Canadian Journal of Biochemistry and Physiology, 1954Adsorption 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 ...

Fluorescence Spectral Properties of Methyl Orange in Homogeneous Media
Journal of Fluorescence, 2021The methyl orange [C14H14N3SO3Na], an azo dye exhibited strong emission and large Stokes shift in various solvents, and the largest shift (Δλ = 125.51nm or Δν = 9297cm-1) was obtained in the water. The UV-visible spectra of the dye showed the absorption in the range (33,333 - 20,000) cm-1.

On the driving forces for complexation of methyl orange with polycations
Journal of Colloid and Interface Science, 2017Complexation between Methyl orange and polycations involves multiple interactions dictated by molecular structure, composition (D/P), pH and ionic strength. The effect of ionic strength is considered a generic effect. By step-wise construction of complexes, we expect to gain insight in the nature of interactions and whether displacement by competing ...
