Researchers performed a laboratory investigation of color removal from reactive dye effluent using activated carbon derived from rice busks. The investigation prepared and filtered a stock dye solution and measured the optical density of the residual liquor using a spectrophotometr. Variations in dye concentration, carbon load, pH, and solution shaking time assessed the effects of each parameter on the color removal process. Results indicated that a higher percentage of dye removal was obtained at either very acidic or very alkaline condition. The percentage of dye removal decreased when the dye concentration was increased. Percent dye adsorption increased up to a carbon load of 1,600 parts per million, then remained constant even at a carbon load of 2,000 parts per million. Increased solution shaking time caused a slight increase in the percentage of dye adsorption by the carbon. Color removal for cotton fabric was 75 percent. 4 refs.
