Sharipov, Kongiratbay, Zaynutdinova, Umida
Abstract
In this study, cadmium ions were estimated in a new and simple way using green chemistry method, including the construction of an ion-selective electrode of nano-coated cadmium oxide (R-CdONPs) using Leucaena Leaves extract as a nanomaterial, Several techniques (SEM, XRD) were used to characterize the characteristics their. Through the XRD technique, the size of the nanoelectrode particles was observed to be 9.57 nm, Through the SEM technique, observed good crystallinity of prepared cadmium oxides nanoparticles (CdO NPs), The particles were seen by SEM to be spherical or semi-spherical in form. The results of the observation were pH (4-6), temperature range between (15-30) C˚, and response time (2-37). Secondly,the concentration calibration curve was a linear response of 1×10-1 - 1×10-11 M with a slope of-27.336 mV/decade, correlation coefficient (0.9975), detection limit (11.67 ×10-11) M, and electrode lifespan of 61 days, and recovery percentage 99.5- 100 %. This method was applied to determine the cadmium ions in industrial water.
