The Sn(II) Reduction of Methyl Orange
The Journal of Physical Chemistry, 1959The reaction between Sn/sup 2+/ and methyl orange was found to be first order in Sn/sup 2+/ and first order in methyl orange in the presence of chloride at all concentrations. The reduction rates of methyl orange for SnCl/sub 2/ complexes were calculated. (C. J. G.)

Competitive adsorption of methyl orange and ethyl orange by AB-8 resin
Emerging Materials Research, 2017Electrostatic attraction and hydrophobic interaction play important roles in the competitive adsorption of dyes. pH and ionic strength are two major factors that affect the competitive adsorption of dyes. Therefore, in this paper, the influences of pH and ionic strength on the competitive adsorption of dyes by AB-8 resin were studied comprehensively ...

Adaptation of the methyl orange method for the determination of reserpine
Experientia, 1958Une methode microcolorimetrique est proposee pour la determination de la reserpine dans les preparations pharmaceutiques et le materiel biologique. La reserpine est extraite des solutions legerement acides avec du dichlorure d'ethyle, puis est melange au methyl orange pour former un complexe dans le solvent organique.

Adsorption and decolorization kinetics of methyl orange by anaerobic sludge
Applied Microbiology and Biotechnology, 2011Adsorption and decolorization kinetics of methyl orange (MO) by anaerobic sludge in anaerobic sequencing batch reactors were investigated. The anaerobic sludge was found to have a saturated adsorption capacity of 36 ± 1 mg g MLSS(-1) to MO. UV/visible spectrophotometer and high-performance liquid chromatography analytical results indicated that the MO ...

Theoretical and experimental investigation of the second hyperpolarizabilities of methyl orange
The Journal of Chemical Physics, 2005We describe experimental and theoretical studies of the third-order nonlinear optical coefficients of methyl orange solutions under different pH conditions. A combination of semiempirical and ab initio methods was adopted to investigate the most stable geometrical structures possible for this molecule.

Acridine Orange—Methyl Green Fluorescent Staining of Nucleoli
Stain Technology, 1981The staining of nucleoli with the fluorescent dye acridine orange following by counter-staining with methyl green differentially stained nucleoli in both plant and animal cells. The nucleoli fluoresced as bright structures highlighted against the quenched fluorescence of the chromatin. This technique provides a simple and highly reproducible method for

Study on degradation of methyl orange using pelagite as photocatalyst
Journal of Hazardous Materials, 2006Pelagite of East Pacific Ocean as a low-price, very high reserve photocatalyst, has been successfully used for the first time to realize total degradation and decoloration of methyl orange within 120 min through photocatalysis. The photocatalysis and degradation performance of pelagite for methyl orange under the effect of various factors has been ...

Chitosan/maghemite composite: A magsorbent for the adsorption of methyl orange
Journal of Colloid and Interface Science, 2013In this study, magnetic beads were prepared by encapsulation of magnetic nanoparticles in epichlorohydrin cross-linked chitosan beads. Their adsorption characteristics were assessed by using methyl orange (MO) as an adsorbate. MO adsorption onto chitosan beads was found to be optimal in the pH range of 3-5. The adsorption isotherm was well described by
