Abstract : Synthetic dyes have a complex aromatic molecular structure. Effluent of dye industries contains a number of contaminants, such as acid or caustic dissolved and suspended solids, toxic compounds, and colouring pigments. In the present article, sulfonated urea–formaldehyde resin was used to decolorize dye effluent obtained from textile industries. Sulfonated urea–formaldehyde resin is used because of their low cost and local availability. Textile effluents were collected and treated with various mixtures of sulfonated urea–formaldehyde resin, rice husk and animal charcoal. The resultant liquids were almost colourless with very low chemical oxygen demands. Adsorption properties were investigated under different conditions.
