Electrochemical determination of Pantothenic acid of human blood using a sensitive film of ZnNPs/2-amino-5-cholorobenzophenone

Abstract

This research is focused on the construction and design of a voltammetry platform to be used for the electrochemical measurement of vitamin B5. Considering the importance and power of the cyclic voltammetry technique in the direction of producing thin and durable electrochemical films, this technique was used for the electrochemical deposition and electropolymerization of surface modifying materials such as zinc oxide nanoparticles and 2-amino-5-chlorobenzophenone. Electrode produced with zinc oxide/2-amino-5-chlorobenzophenone nanofilm structure, at the optimal pH of 6 and under the optimal chemical and device conditions, it could have a linear behavior in the range of 20 to 200 nM and the detection limit was 6.61 and the minimum limit was 19.98 nM. Also, an outstanding electrocatalytic behavior with the obtained parameters of transfer coefficient (i.e. α equal to 0.61), the logarithm of the speed constant (log Ks equal to 3.42)
