Simultaneous determination of Cd(II) and Pb(II) using electrode modified by FeAl2O4-AlOOH-reduced graphene oxide hybrids

A new kind of electrode composed of FeAl2O4 nanoparticles, γ-AlOOH, and reduced graphene oxide (rGO) was prepared for the simultaneous determination of Cd(II) and Pb(II) in aqueous solution using square wave anodic stripping voltammetry (SWASV). γ-AlOOH was employed to modify rGO to obtain a platform for distributing FeAl2O4 particles uniformly. The phase and structure of the FeAl2O4-AlOOH-rGO composites were characterized using scanning...
