Removal of dyes from an artificial textile dye effluent by two agricultural waste residues, corncob and barley husk

摘要

The use of a previously untried biosorbent, barley husk, for dye removal is compared to corncob. The effectiveness of adsorption as a means of dye removal has made it an ideal alternative to other more costly treatments. This paper deals with two low-cost, renewable biosorbents, which are agroindustrial by-products, for textile dye removal. Experiments at total dye concentrations of 10, 20, 30, 40, 50, 100, 150, and 200 mg 1~-1 were carried out with an artificial effluent consisting of an equal mixture of five textile dyes.
