The Nano-PY-MCM-41@Fe3O4 (NPMF), a new kind of nano material, was prepared by the hydrothermal method. In this work, its characteristic and the composite construction were analyzed through such series of means as SEM, TEM, IR, TGA, XRD, VSM, N2 adsorption desorption isotherm curve and so on, the adsorption capacity of NPMF for the low concentration uranium-bearing solutions was investigated through NPMF adsorption for U(VI) experiment and cycle adsorption experiment, the effects of initial pH, adsorption temperature, contact time and other fact...
