“…In contrary to the above analytical techniques, electrochemical sensing enables the low cost detection of heavy metals and it requires simple instrumentation [12,13]. In electrochemical sensing, the extent of sensitivity and the range of selectivity depends on the electrode modifier used [14,15]. Thus, to improve the efficiency of electrode, a suitable electrode modifier is required.…”

Nano particulate metal oxides gained significant research interest in recent years for various applications with the intension of exploring enhanced properties of miniaturization. In this research work, nickel tungstate nanoparticles (NiWO 4 nanoparticles) were successfully synthesized via a simple and efficient sucrose-nitrate decomposition method. The synthesized nanoparticles were characterized using various analytical techniques such as PXRD, SEM, TEM, BET measurements and FTIR. Transmission electron microscope images reveals the nearly spherical shaped nanoparticles of average particle size 15-35 nm. Photoluminescence characteristics of synthesized NiWO 4 nanoparticles were investigated at room temperature. Further, the prepared nanoparticles were utilized as glassy carbon electrode modifier for trace level electrochemical sensing of toxic mercury present in water samples. The electrochemical behavior of mercury(II) ions at modified electrode interface has been studied by cyclic voltammetry (CV) and differential pulse stripping voltammetry (DPSV). The results illustrate that, the proposed modified GCE sensor exhibits linearity between the concentration range 10-600 nM with the limit of detection 2.25 nM based on 3σ method for mercury(II) ions. Hanumantharayappa Eranjaneya and Prashanth Shivappa Adarakatti have contributed equally.
