Title: Sensitive and selective detection of multiple water contaminants using modified glassy carbon electrodes
Electrochemical sensors (ES) are currently the leading probes for monitoring water contaminants. These can respond to physical or chemical stimuli and convert the sensing event into measurable signals. ES contain a recognition element that recognizes a particular analyte, a transducer/detector device that produces a signal and a processor that collects, amplifies, and displays the signal. ES can detect organic and inorganic water toxins below the threshold level suggested by the World Health Organization. Selection of suitable electrode modifiers can dramatic boost up the current response of the target analytes. This current work is focused on the development of electrochemical sensors demonstrating remarkable electrocatalytic activity and excellent discrimination ability for the target analytes in the presence of even 200-fold higher concentration of interfering agents.
