A highly sensitive determination of sulfite using a glassy carbon electrode modified with gold nanoparticles-reduced graphene oxide nano-composites

A gold nanoparticles-reduced graphene oxide composite (AuNPs-rGO) was synthesized by chemical co-reduction strategy using ethylene glycol (EG) as a reducing agent. This AuNPs-rGO composite modified electrode exhibited high electrochemical activity and attractive analytical features for the detection of sulfite.171
