Congo red, a diazo anionic dye, is a sodium salt of benzidinediazo-bis-1-naphthylamine-4-sulfonic acid. The color of the dye shows the pH dependency as in basic medium, the red color of dye appears and turns into blue color when medium changes to acidic. Large volume discharges of Congo red dye that are elaborated with benzidine into a water body constitute a health risk to human bodies and aquatic lives.

The adsorbate used in this study is Congo red (CR) dye. It is the sodium salt of benzidinediazo-bis-1-naphthylamine-4-sulfonic acid; molecular formula, C32H22N6Na2O6S2; molecular weight, 696.66 g/mol; CI number, 22 120; λmax, 497 nm. It is a secondary diazo dye. CR was obtained from M/s Merck, and its solution was prepared by dissolving accurately weighed the amount of dye in distilled water. Different concentrations (20–100 mg/L) were prepared by serial dilution with distilled water.
