摘要: A new magnetic adsorbent PAMAMG3-Fe3O4/P(GMA-AA-MMA) was prepared by growing third generation poly(amido) amine (PAMAMG3) on the surface of superparamagnetic polymer microspheres Fe3O4/P(GMA-AA-MMA). The maximum sorption capacity U(VI) (395.2 mg g−1) sorbent much higher than those many other reported materials. obeyed Langmuir mode. selectivity could reach up to 91.8 % at pH 4.5. Furthermore, also be reused least five times without any noticeable loss its capacity.
