A nano-sensor for copper oxide was manufactured and developed using a new organic precipitant via green chemistry methods

Abstract

Green chemistry methods were applied to fabricate a nanoelectrode to capture copper ions for the first time using the new organic reagent (4-(3-(2-(3-nitrophenyl)-4,7-dioxo-1,3-oxazepin-3(2H, 4H, (7H)- yl) thioureido. The ionic double was prepared to manufacture the new copper oxide nanoelectrode from the reaction of the new organic reagent and used it as an organic precipitant with CuO-NP nanoparticles prepared from cinnamon extract using the simple green aqueous method. Several techniques were used (XRD, FTIR, SEM) to characterize these particles. This electrode shows excellent selectivity and sensitivity with a linear range of (10-3 -10-13) M, correlation coefficient (0.9998), electrode life of 77 days, ideal temperatures (30) °C and range Optimum pH (3-9), slope (11.082 mV/decade), limit of detection (9.79×10-13) M. The average crystal size measured by the XRD device was (25) nm. The particles were seen by SEM as spherical. Or almost spherical in shape. UV-Visible spectroscopy, the peak was at wave length at (798) nm. This confirms that nanoparticles have been obtained for Copper material. Functional aggregates were determined by FTIR measurement. Recovery value of (101.1) %. This method was successfully applied to estimate copper ions in polluted water.
