Sugar cane bagasse was crosslinked with epichlorohydrin in the presence of NH4OH or imidazole. The obtained water-insoluble products were characterized in terms of yield, anion-exchange capacity, packed volume, and dye-binding properties. Yields were highest using a 3 : 1 epichlorohydrin to NH4OH molar ratio, producing weak anion exchangers. The weak anion exchangers had low dye-binding capacities compared to their total anion-exchange capacities. A 2 : 1 epichlorohydrin-to-imidazole molar ratio proved best for making strong anion exchangers from bagasse. The strong anion exchangers had dye-binding capacities comparable to their anion-exchange capacities, indicating that they might be useful for removing anionic dyes from wastewater.
