Abstract
An electrochemical method for measuring the concentration of an anionically-charged and non-electroactive polymer in an aqueous solution is provided. The method comprises immobilizing a cationic dye material on an electrically conductive substrate form a working electrode; contacting the working electrode with the aqueous solution including the anionically-charged and non-electroactive polymer to be measured, and transmitting electrical power to the working electrode; measuring a current of the working electrode under a determined electric potential; and calculating a concentration or quantity of the anionically-charged polymer in the aqueous solution according to the measured current of the working electrode.
