Cyanide is one of the most toxic inorganic anions, it is very harmful to human health but extremely useful in industrial activities. Herein, we used our recently reported boradiazaindacene (BODIPY) dye, 3,5-diformyl-borondipyrromethene (BODIPY 1) as an exclusive chemodosimetric and colorimetric sensor for CN(-) ion. Cyanide ion attacks the carbonyl groups of 1 via a nucleophilic addition reacti...

The problem of textile dye pollution has been addressed by various methods, mainly physical, chemical, biological, and acoustical. These methods mainly separate and/or remove the dye present in water. Recently, advanced oxidation processes (AOP) have been focused for removal of dye from waste water due to their advantages such as ecofriendly, economic and capable to degrade many dyes or organic...

Coloring of hair can cause severe allergic contact dermatitis. The most frequently reported hair dye allergens are p-phenylenediamine (PPD) and toluene-2,5-diamine. We present a 20-year-old man who came to emergency room with head and face edema. His head and neck skin was diffusely erythematous, oozing with blisters and crusts. Some of the crusts on the back of his neck were pyodermic. Submand...

This study concerns the decolorization and detoxification of the azo dye Acid Orange 51 (AO51) by crude laccase from Trametes trogii produced in solid culture using sawdust as support media. A three-level Box-Behnken factorial design with four factors (enzyme concentration, 1-hydroxybenzotriazole (HBT) concentration, dye concentration and reaction time) combined with response surface methodolog...

Dye-sensitized solar cell (DSSC) provides high ability of renewable energy generation. One the main factors affects performance DSSC is type dye applied as a sensitizer. Natural sensitizers have become major concern due to widely availability in world and environmentally friendly characteristic. However, need improve natural dyes based very important. This review was conducted present recent st...
