The amidoximation process of polyacrylonitrile fiber was studied. The results showed that it is possible to prepare a chelating fiber with high adsorption capability for Au 3Γ· and reasonable mechanical properties by the amidoximation of PAN fiber. With an increase of reaction time or concentration o

Three kinds of redox fibers (fibers II, III, and IV) are prepared by amination of the reactive chloromethylated poly(vinyl acetate) grafting polystyrene-divinylbenzene fiber (fiber I) with diethanolamine, ethanolamine, or triethanolamine. The Ncontent of the fibers is 2.26, 2.71, and 1.86 mmol g Οͺ1
## Abstract In this study, we explored a new ion exchange material synthesized by radical polymerization of styrene and 2βacrylamidoβ2βmethylβ1βpropane sulfonic acid by using 2,2β²βazoβisobutyronitrile (1 mol %) and divinylbenzene (0.5 mol %) as initiator and crosslinking reagents, respectively. The
