Quantification of Adsorption of Azo Dye Molecules on Graphene Oxide Using Optical Spectroscopy
, 2017 The presence of azo dye molecules in effluents is a source of water pollution and an environmental hazard. Thus, it is very important to separate out such dye molecules.

Study the nonlinear optical property of pull/push type azo dye-doped polymer using 633nm He–Ne laser
, 2017 Azo dyes with different pull/push substituents are selected as photosensitive molecules. Guest–host amorphous azo polymer samples are prepared by doping these azo dyes directly in poly(methyl methacrylate) polymeric matrices.

Photoinduced ordering and anchoring properties of azo-dye films
, 2005 We study both theoretically and experimentally the anchoring properties of photoaligning azo-dye films in contact with a nematic liquid crystal depending on the photoinduced ordering of azo-dye molecules.

Coloration Technology, EarlyView.Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

A Three-Step Synthesis of Azo Dye [PDF]
, 2015 Organol brown azo dye was synthesized and altered with functional group conversions to see the effect it would have on its color. This allowed for the testing of what reactions can be used to create new variations of azo dyes.

Azo dye formation in 5-hydroxycoumarins
, 1944 The 5-hydroxycoumarins behave very similar to 7-hydroxycoumarins in regard to azo-dye formation with one and more than two molecular proportions of diazotisedp-nitraniline.

Advances in organic UV filters for sunscreens over the past decade
Photochemistry and Photobiology, EarlyView.Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Investigating the Efficiency of Wastewater Treatment Plant Sludge in Removing Azo Dye Reactive Red 195 from Synthetic Wastewater in Aerobic and Anaerobic Conditions [PDF]
Journal of Mazandaran University of Medical SciencesBackground and purpose: Azo dyes are present in the wastewater of most textile factories, and if they enter water resources, they pose risks to the health of humans and the living environment due to the effects of toxicity, biological accumulation, and ...
