Abstract :The presented work demonstrates the preparation of copper nanoparticles insert ignore into journalissuearticles values(CuNPs); via aqueous leaves extract of Ziziphus mauritiana L insert ignore into journalissuearticles values(Zm); using hydrazine as a reducing agent. Various parameters such as volume of extract, concentration of hydrazine hydrate, concentration of copper chloride, and pl 1 of the solution were optimized to obtain Ziziphus mauritiana 1. leaves extract derived copper nanoparticles insert ignore into journalissuearticles values(Zm-CuNPs);. Brownish red color was initial indication of the formation of Zm-CuNPs while it was confirmed by surface plasmon resonance insert ignore into journalissuearticles values(SPR); band at wavelength of 584 nm using ultraviolet-visible insert ignore into journalissuearticles values(UV-vis); spectroscopy. Synthesized Zm-CuNPs were characterized by Fourier transform infrared spectroscopy insert ignore into journalissuearticles values(FT-IR);, scanning electron microscopy insert ignore into journalissuearticles values(SEM);, atomic force microscopy insert ignore into journalissuearticles values(AIM, and X-ray diffractometry insert ignore into journalissuearticles values(XRD);. AFM images showed that the particle size of Zm-CuNPs was from 7 to 17 nm with an average size of 11.3 nm. Fabricated sensor insert ignore into journalissuearticles values(Zm-CuNPs); were used as a colorimetric sensor for the detection of Ag+ at a linear range between 0.67 x 10insert ignore into journalissuearticles values(-6);- 9.3 x 10insert ignore into journalissuearticles values(-6); with R-2 value of 0.992. For real water samples, limit of quantification insert ignore into journalissuearticles values(LOQ); and limit of detection insert ignore into journalissuearticles values(LOD); for Ag+ was found to be 330 x 10insert ignore into journalissuearticles values(-9); and 100 x 10insert ignore into journalissuearticles values(-9); , respectively.
