Preparation of Modified Polyurethane Fiber and Study of its Lead Ions Adsorption

Abstract:

Modified polyurethane fiber was prepared by wet spinning method, Different amount of chitosan powder that dissolving in polyurethane solution to get spinning solution were examined. This materials presents excellent adsorption capacity on Pb²⁺. the absorption type on Pb²⁺ of this modified fibers was monomolecular. The modified fibers get the maximum adsorption 25.53mg/g when the quality ratio of chitosan and polyurethane was 1:1 under the condition of 30°C and pH 6.
