Abstract: Outstanding conductivity and biocompatibility of Carbon nanotube (CNT) and conducting polymer (CP) have shown the unparalleled superiorities in the area of electrochemical sensors. Emphasis has been given on the types of functionalization, fabrication of sensor, role of graphite, CNT and CP in environment monitoring and assay strategies. It is very important to develop a simple, effective, sensible, reliable and accurate method to detect heavy metals present in the environment as a pollutant. Other traditional or conventional methods like Atomic Absorption Spectrophotometer, Flame Photometer, Gravimetery etc. have their own limitations and disadvantages. We have fabricated novel graphite, CNT and CP (polyaniline) based amperometric sensor for the detection of Zinc metal as an environment pollutant. The electrochemical performance of amperometric sensor was tested by Cyclic Voltammetry, Ampereometry and Linear Sweep Voltammetry experiments. The developed amperometric sensor displays good electrochemical activity towards the detection of Zinc present in the environment. Storage and stability conditions were also tested.

 

Keywords: Amperometric Sensor, Conducting polymer, Electrochemical biosensor, Environmental pollutant, Zinc.
