In the present study, phosphotungstic acid decorated on magnetic amine-grafted graphene oxide (GO-Amine/Fe3O4/H3PW12O40</sub>; GOA/Fe3O4/HPW) was prepared and evaluated as a new adsorbent for removal and separation of organic dyes from water. The obtained nanocomposite was fully characterized by means of XRD, FT-IR, Raman, VSM, SEM, EDX, AFM and BET surface area analysis. The results demonstrated […]
