Abstract: Abstract A new kind of poly(propylene imine) (PPI) functionalized-graphene oxide fully covered polystyrene-divinylbenzene (PS/DVB) microspheres, named PS/DVB@GO-PPI, has been designed and synthesized. The PS/DVB@GO-PPI was used as a new dispersive solid-phase extraction material for simultaneous… read more here.
