Nanocomposite-graphene based platform for heavy metal detection
(University of the Western Cape, 2010)
This study reports the synthesis of graphene by oxidizing graphite to graphite oxide using H2SO4 and KMnO4 and reducing graphene oxide to graphene by using NaBH4. Graphene was then characterized using FT-IR, TEM, AFM, XRD, ...
Graphene-modified pencil graphite bismuth-film electrodes for the determination of heavy metals in water samples using anodic stripping voltammetry
(University of the Western Cape, 2013)
Electrochemical platforms were developed based on pencil graphite electrodes (PGEs) modified with electrochemically deposited graphene (EG) sheets and Nafion-graphene (NG) nanocomposites in conjunction with an in situ ...
