Abstract
A new anion-exchange resin is prepared through the reaction of sawdust, as an inexpensive cellulosic backbone, melamine formaldehyde precondensate (MF), as a cross-linking, reinforcing, and binding agent, along with triethanolamine hydrochloride (TEA·HCl), as a catalyst for and a corereactive with the cross linker, at elevated temperature so that insoluble cross-linked networks are produced with pendent tertiary amino groups. Factors affecting the resin formation, such as reactant concentration, liquor ratio, reaction time, and reaction temperature, are studied. Proper conditions are selected to prepare an anion exchanger having an amino content of 88 mEq/100 g. Potentiometric titration of the prepared exchanger showed that this resin is a weak base anion exchanger with a strength pKb of 10.
