Methyl orange adsorption studies on glutaraldehyde cross-linking chitosan/fluorapatite-based natural phosphate composite

International Journal of Environmental Analytical Chemistry, 2022
In this work, chitosan, a biopolymer was cross-linked using glutaraldehyde (Gl) and modified by natural apatite. The Cs-Gl@Fap composite was used to adsorb methyl orange from an aqueous solution. The materials were characterised by SEM-EDX, FTIR, XRD and

Combining structurally ordered intermetallic nodes: Kinetic and isothermal studies for removal of malachite green and methyl orange with mechanistic aspects

Microchemical journal (Print), 2021
The current research focus is to develop some systematic materials for the removal of hazardous dyes from water to save the aquatic environment. We have reported the in-situ growth of zeolitic imidazolate frameworks (ZIF-8) on zinc layered double ...

The demethylation of m-methyl orange and methyl orange in vivo and in vitro

Biochemical Pharmacology, 1966
Abstract 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, 1994
Biphoton 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 ...

Preparation and characterization of lignin-derived hard templated carbon(s): Statistical optimization and methyl orange adsorption isotherm studies.

Bioresource Technology, 2021
In this study, lignin-derived zeolite templated carbon materials were fabricated to remove the organic contaminant, methyl orange. Response surface methodology with Box-Behnken design was used to optimize the adsorption parameters.

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

Australian 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 ...

Preparation of chitosan crosslinked with metal-organic framework (MOF-199)@aminated graphene oxide aerogel for the adsorption of formaldehyde gas and methyl orange.

International Journal of Biological Macromolecules, 2021
Chitosan crosslinked with metal-organic framework (MOF-199)@aminated graphene oxide aerogel (MOF-199@AFGO/CS) were prepared to adsorb formaldehyde and methyl orange. The prepared MOF-199@AFGO/CS aerogel was well characterized via SEM, EDX, FT-IR, XRD and
