azo

There are three groups of synthetic dyes such as azo dyes, phthalocyanine and anthraquinone.

Azo dyes represent a major group of dyes causing environmental concern because of their color, bio-recalcitrance, and potential toxicity to animal and human (Pierce et al., 2003; Forgacs et al., 2004).

In Brazil, the Ministry of Health, through the Agencia Nacional de Vigilancia Sanitaria-ANVISA, allows the use of azo dyes in the food industry for coloring foodstuff and juices.

According to the statement, azo dyes could release carcinogenic substances known as aromatic amines when they mix with sweat, which accounted for the ban on the use of the dye in many countries of the world.

Everyday activities and stressors, from sexual activity to tight clothing, diet and medication, can all disrupt vaginal health, according to AZO. The company has developed its new probiotic to work naturally with a woman's body and help restore the balance of good bacteria and yeast that can be thrown off by common disrupting factors.

This phenomenon of degrading the variety of pollutant is generally due to syntrophic interactions among the mixed communities which lead to complete mineralization of azo dyes (Chang et al., 2004; Fude et al, 1994; Khehra et al., 2005; Asgher et al., 2007).

In this work, the relationship between the structure and the dielectric properties of the azo polymers was studied.

A thin Ag layer is inserted between the top ITO and bottom AZO layers.

As far as we know, there are few reports about the comparison between Ag initial growth and spreading on ITO and those on AZO.

Azo precursor 3 (1.5 g, 5 mmol) was added to the solution of 4-bromobutene (0.68 g, 0.51 mL, and 5.0 mmol), tBuOK (0.62 g, 5.0 mmol), and KI (20 mg) in dried acetone (100 mL).
