摘要：The Schiff base metal complexes have wide range of applications in the microbial studies, but there is arecent trend that these Schiff base metal complexes are employed as an electrocatalytic sensor. The electrochemicaldetection is one of the most selective and sensitive method. When compared with other detection methods this methodhas short time duration, cost effective, low detection limits and easy to handle. The Nickel Schiff base complex showsbetter electrochemical redox behaviour, it transfers the electron to heavy toxic metal ions for it redox process. This canbe utilized for the sensing of heavy metal ions in electrochemical method. Heavy metal ions are harmful to the livingorganisms, and toxic to the human health. The heavy metal contamination in the environment causes severe pollution tothe ecological systems. Hence, there is a necessity to develop a simple, sensitive and accurate method for thedetermination of heavy metal ions in the environment. In this work Hg+2 ion was determined by the nickel Schiff basecomplex modified GCE. The modified GCE was electrochemically characterized by cyclic voltammetry and linearsweep voltammetry. This result indicates that the nickel complex modified GCE showed a good linear response withinthe ranges of 16.7 – 166.4 μM and the detection limits were 0.054 nM for Hg+2.
