water-soluble dyes of anionic character; predominantly the anthraquinone and azo dyes.

Acid dyes are widely used in coloring wool, natural silk, polyamide fiber, leather, fur, paper, and wood. They are not adsorbed by cellulose fibers.

Nine derivatives of sulfonic acid dyes were synthesized using substituted aryl amines as diazo component and substituted amino hydroxyl sulfonic acid as coupling component.
Thus, many research works have paid increasing attention to the degradation of acid dyes in the water stream in recent years.
Wool, silk, nylon and protein based natural fibers also have amino group that can bond with acid dyes, the bond formed between the dye and fiber are salt linkages.
Among them, acid dyes are considered to be a logical choice because wool exhibit cationic character owing to the presence of inonizable amino groups as part of the main chain peptide bonds connecting the amino acid units together [6, 7].
The exponential growth of the textile industry in countries such as China, India, Indonesia, Brazil, and Mexico are expected to increase the demand for acid dyes. Factors like availability of raw materials, cost-effective labor, low logistics cost, and favorable government policies are motivating the global dye vendors to shift their manufacturing units to these countries.
Acid dyes can be brought to a neutral state by adding baking soda before disposal.
