Sensitive determination of hydroxylamine on ZnO nanorods/graphene oxide nanosheets modified graphite screen printed electrode

To date,the development of different modified electrodes has received much attention in electrochemistry. hence,we report an electrochemical sensor for the determination of hydroxylamine using zno nanorods/graphene oxide nanosheets modified graphite screen printed electrode electrochemical determination of hydroxylamine reveals that the modified electrode showed lower detection limit of 0.5 μm with a linear ranging from 1.0 to 100.0 μm towards the hydroxylamine concentration via differential pulse voltammetry. the developed sensor also applied to the successfully determination of trace level hydroxylamine in real samples. in addition,the advantage of this type of electrode is simple,disposable and cost effective in electrochemical sensors. © 2017 by cee (center of excellence in electrochemistry).
