POTENTIOMETRIC RESPONSE OF A GRAPHITE ELECTRODE MODIFIED WITH COBALT PHTHALOCYANINE FOR THIOLS AND DISULFIDES
We have investigated the potentiometric response of ordinary pyrolytic graphite electrodes (OPG) modified with cobalt phthalocyanine (Co-Pc) for thiols (R-SH) 2-mercaptoethanol, L-cysteine and their corresponding disulfides (R-SS-R). Stable potentials are achieved after a few seconds of additions of...
