A novel bidentate Schiff base (L) is here proposed for the detection of Zn ions in water. The structure of the synthesized Schiff base L was characterized by FT-IR, 1H NMR and 13C NMR. Optical characteristics were addressed by UV-Visible spectroscopy and Photoluminescence (PL) measurements. PL demonstrated that L displays a “turn-off” type fluorescence quenching in the presence of Zn2+ ion in aqueous solution, indicating its ability to preferentially coordinate this ion. Based on these findings, an L-M (where M is a suitable membrane) modified screen-printed carbon electrode (SPCE) was developed to evaluate the electrochemical behavior of the Schiff base (L) with the final objective of undertaking the electroanalytical determination of Zn ions in water. Using various electrochemical techniques, the modified L-M/SPCE sensor demonstrates high sensitivity and selectivity to Zn ions over some common interferents ions, such as Ca2+, Mg2+, K+, Ni++ and Cd++. The potentiometric response of the L-M/SPCE sensor to Zn ions was found to be linear over a relatively wide concentration range from 1 μM to 100 mM.

“…The two-step method that is used to produce graphene out of graphite in the GO synthesis unit is known as oxidation of graphite to make graphene oxide, and washing and purification of graphene oxide from unwanted compounds ( manganese salts, acids ,etc.) [40][41][42][43]. The modified Hummer method was developed from the graphene oxide sheets in this study.…”

Graphite is a based on three-domination functionalized carbon content made up of millions of graphene layers. In this study, graphene oxide (GO) and graphene oxide\Ag nanocomposites (GO-Ag) have been synthesized in a single layer using a modified Hummer method. The morphology and structural characteristics of GO and GO-Ag nanocomposites were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmitted electron microscopy (TEM), and Raman spectroscopy. The results of TEM indicated the single and double layer structure with thickness of 4-6 nm for GO Nano-sheets prepared in this analysis. The particles size of silver on a surface of GO was to be less than 20 nm.
