It is therefore fundamental to remove the dyes by using various techniques. In the present paper adsorption technique was employed for removal of Congo red dye. Congo red dye is a carcinogenic dye, which comes in the effluents of textile industries during dyeing and rinsing processes. In the present work, the effect of variables such as adsorbent dose and contact time on adsorption of dye was studied. The dose of rice husk charcoal was varied from 0.2 g/l to 2.0 g/l, and contact time was varied from 30 minute to 360 minute. Keeping all factors constant, with the change of dose of rice husk charcoal, it was found that adsorption increases from 0.2 g/l to 1.2 g/l and then it becomes constant; with the change of contact time, the adsorption increases from 30 minute to 210 minute and then becomes constant.
