摘要:
Highly efficient removal of U(VI) from mine radioactive wastewater has received a lot of attention. Herein, the polyamidoxime/polyethyleneimine magnetic graphene oxide (mGO-PP) adsorbent was successfully prepared by in situ polymerization of acrylonitrile on magnetic GO (mGO) covalently modified with polyethylenimine (PEI). The mGO-PP was characterized by Fourier transform infrared (FT-IR), scanning electron microscopy, transmission electron microscopy, vibrating sample magnetometer, and X-ray photoelectron spectroscopy (XPS). The maximum adsor...
