Voltammetric determination of uric acid in kidney and chronic kidney disease urine samples relies on a mercury electrode

Abstract

   A voltammetric method has been described that is characterized by speed and high accuracy, and at the same time it is considered a sensitive and fast method compared to traditional methods for determining uric acid in urine. The method was determined that relies on the use of a mercury electrode as the basic substrate for the working electrode through the use of two different techniques at the same time for the purpose of uric acid determination. Uric acid based on uric acid reduction wave. In the presence of acetate buffer solution with a pH of 7.0, the optimal conditions that affect the method were studied, such as the pH, equilibrium time, and volume of the reducing agent. The size of the model through the sequence of addition of samples against the reference electrode (Ag/AgCl) in the presence of (KCl) with a concentration of (3) molar at a clear reduction wave at a voltage of (-0.6) volts and gave results with regular linear relationships for all the methods used and they were applied and compared. By traditional methods of measurement using Spectrophotometric.
