Composite of Cu metal nanoparticles-multiwall carbon nanotubes-reduced graphene oxide as a novel and high performance platform of the electrochemical sensor for simultaneous determination of nitrite and nitrate
An electrochemical sensor based on Cu metal nanoparticles-multiwall carbon nanotubes-reduced graphene oxide modified glassy carbon electrode was developed. Simultaneous electrochemical determination of nitrate and nitrite by fabricated sensor was performed. Modification improved the sensitivity and detection limit of the method. It is a useful method for determining of nitrate and nitrite in various real samples.
