A pyridine sulfonamide containing resinous polymer has been prepared starting from crosslinked polystyrene 10% divinylbenzene (DVB) resin beads (420-590 mu m) by the following series of reactions: chlorosulfonation and sulfonamidation with 4-amino pyridine. Dye extraction experiments were carried out simply by contacting wetted resin samples with aqueous dye solutions at room temperature. Capacities were determined by colorimetric analysis of the residual dye contents. Dye sorption capacity of the resin was found to be 0.77 g per gram resin for calcon. This material is also able to remove the anionic dyes completely even from highly diluted aqueous dye solutions. Copyright (C) 2008 John Wiley & Sons, Ltd.
