Electrochemical Determination of Inorganic Phosphate
An electrochemical phosphate sensor based on the precipitation of molybdophosphate on electrode surface was developed for the determination of inorganic phosphate. The condition for the formation of the molybdophosphate was studied and cyclic voltammetry and differential pulse voltammetry were utilized for the determination. A detection limit of 10 ppm was obtained and the sensor response was approximate liner in the range between 10-100 ppm.
