Abstract

Polyurethane (PU) possesses excellent mechanical properties which has been used as the matrix for heavy metal ions removal. However, it has poor adsorption capacity due to there doesn’t exist chelating groups. In this study, phytic acid modified polyurethane (PU) fibers have been successfully prepared by wet spinning which was used for Pb2+ removal. The modified fibers achieved the highest adsorption capacity under the conditions of the mass ratio of phytic acid and PU was 5:7, the pH of Pb2+ solution was 6 and the adsorption temperature was 20 °C. The adsorption process of Pb2+ by phytic acid modified PU fibers belongs to monolayer adsorption. The saturated Pb2+ adsorption capacity of the modified PU fibers was over 7 times higher than the pure one’s. Phytic acid modified PU fibers could greatly improve the adsorption capacity of Pb2+ which could be used as the potential adsorbent for heavy metal ions removal.
