Isolation and screening of azo dye decolorizing bacterial isolates from dye-contaminated textile wastewater

Soil & Environment, 2011
Azo dyes are released into wastewater streams without any pretreatment and pollute water and soilenvironments. To prevent contamination of our vulnerable resources, removal of these dye pollutants is of greatimportance.

Spectrophotometric determination of salbutamol sulphate in bulk and in pharmaceutical formulations

مجلة بغداد للعلوم
A new simple and sensitive colorimetric method has been developed for determination of salbutamol in aqueous solutions. The method is based on the formation of a yellow colored azo dye by diazotization of 2,4-dichloroaniline, followed by a azo-coupling ...

Design, synthesis and spectroscopic characterisation of novel azo dyes incorporating benzimidazole moiety

Discover Chemistry
This study describes the design, synthesis and characterisation of benzimidazole-derived azo dyes. Ten novel azo acid dyes were synthesized from benzimidazole derivatives using H-acid, Gamma acid, J-acid and Tobias acid as the coupling components.
