Title
Ag/g-C3N4 as a new platform for surface modification of carbon ceramic electrode (CCE) for iodate determination
Type of Research Presentation
Keywords
Ag/g-C3N4
Abstract
Silver doped graphitic carbon nitride nanocamposite was synthesized in one step procces by thermal treatment using of urea as an abundant and inexpensive precursor [1]. The properties of resulting Ag/g-C3N4 nanocamposite was investigated by various techniques such as Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy(TEM). The Ag/g-C3N4 was used as a new platform for surface modification of carbon ceramic electrode (CCE) by casting. The electrocatalitical behavior and stability of modiefied electrode was investigated by cyclic voltammetry. Finally Ag/g-C3N4/CCE was used as an iodate sensor which showed an efficient catalytic effect on the electrochemical reduction of iodate. The effects of solution pH and scan rate on the reduction of iodate was surveid. Calibration curve was ploted by chronoamperometic method. The selectivity and lifetime of the electrode were studied and table salt and sea salt were used as real samples for studing applicability of modified electrode. The liner range
