Magnetic Fe3O4 nanoparticles were prepared on graphene oxide (Fe3O4/GO) in situ in a one step process. The obtained Fe3O4/GO was used as an adsorbent for the removal for Pb …
A co-precipitation method was developed to separate and pre-concentrate Ni (II), Cu (II) and Zn (II) ions using an organic coprecipitant, chrysin without adding any carrier element …
