摘要：
A polyacrylonitrile-TiO2 composite adsorbent bead was prepared to remove Pb2+ ion in aqueous solution. The dual nozzle technique was applied to prepare a spherical bead. The prepared composite adsorbent was found to be highly porous and stable against strong acids. Adsorption tests showed that Ph2+ ion adsorption increased in proportion to pH and Ph2+ ion was completely removed at pH 5.60. The equilibrium and kinetic parameters such as equilibrium constant, adsorption capacity, film mass-transfer coefficient, and effective diffusivity were also evaluated by modeling the experimental data.
