Electrochemical profile degradation of amino acid by flow system using TiO2/Ti nanotubes electrode

The new method of electrochemical degradation of amino acid by flow system using tio2/ti electrode had been carried out. the electrode was synthesized by anodic oxidation processes and analyzed its electrochemical profile degradation. the development of the flow system for determining the profile and photocurrent response of amino acid,i.e phenylalanine,glycine,and glutamine were performed by using linear sweep voltammetry (lsv),multi-pulse amperometry (mpa) and cyclic voltammetry (cv) techniques. the optimum ph measurement of phenylalanine,glycine,and glutamine were 8.54,7.80 and 8.53,respectively. data on photocurrent response showed the phenylalanine,glycine and glutamine were proportional to the increasing concentration. the photocurrent response with the addition of electrolyte on the analyte showed that the photocurrent response was higher than the ceq(formula presented) value of each amino acid (196.9825 μa phenylalanine; 130.3333 μa glycine; 194.0193 μa glutamine) whereas without using electrolyte of each amino acid: 84.56667 μa phenylalanine; 60.55863 μa glycine; 91.79087 μa glutamine. this system design is potentially developed for chemical oxygen demand (cod) sensor. © 2016 by cee (center of excellence in electrochemistry).
