The biodegradation of hydroquinone

Environmental Toxicology and Chemistry, 1982
AbstractHydroquinone is readily degraded by an acclimated activated sludge unit when present at concentrations of 100 mg/L in synthetic photographic or synthetic domestic wastes. A number of pure cultures of yeasts, fungi, and bacteria were isolated from soil and sludges which can utilize hydroquinone as a sole carbon source.1,4-Benzoquinone, 2-hydroxy-

A comparative study of topical 5% cysteamine versus 4% hydroquinone in the treatment of facial melasma in women

International Journal of Dermatology, 2020
To assess the efficacy and safety of topical 5% cysteamine versus 4% hydroquinone in the treatment of facial melasma in women. Topical 5% cysteamine is an antioxidant and tyrosinase inhibitor that has been shown to be effective in the treatment of ...

High-efficiency adsorption of and competition between phenol and hydroquinone in aqueous solution on highly cationic amino-poly(vinylamine)-functionalized GO-(o-MWCNTs) magnetic nanohybrids

, 2020
A novel highly cationic amino-poly(vinylamine) (PVAm)-functionalized GO-(o-MWCNTs)-Fe3O4 three-dimensional nanohybrid adsorbent with a large surface area and abundant amino groups was developed via a simple one-pot reaction.

Hydroquinone: myths and reality

Clincal and Experimental Dermatology, 2020
Hydroquinone has pharmacological uses in disorders of pigmentation because of its ability to competitively inhibit the enzyme tyrosinase. Our contemporary review presents the strongest evidence supporting the use of hydroquinone with the most effective ...

Sensitive detection of hydroquinone based on electrochemiluminescence energy transfer between the exited ZnSe quantum dots and benzoquinone

Sensors and Actuators B: Chemical, 2018
We proposed a signal amplification strategy designed for sensitive electrochemiluminescence (ECL) detection of hydroquinone (HQE) in water. The detection mechanism is based on the ECL energy transfer (ET) can generate between the excited ZnSe quantum ...
