Abstract: A sensor for measurement of free chlorine and of total chlorine in aqueous solution including a working electrode having a self-assembled monolayer (SAM) formed on the surface thereof, producing a barrier which reduces the generation of background currents when electrical potentials are applied to the electrode, and blocks the reduction or oxidation of interfering species in the solution, is described. Such SAMs have also been found to block the efficient reduction of chlorine as well. However, N,N-diethyl-p-phenylenediamine (DPD) has been found to effectively transport electrons across the SAM; that is, an oxidized form of DPD produced by a reaction with chlorine is capable of penetrating the SAM such that the reduction of the oxidized DPD species can occur. The generated reduction current is correlated with the concentration of chlorine in solution. Total chlorine may be determined by the addition of an iodide salt.
