A simple and efficient method for determining dissolved oxygen at pH 6.5 is proposed using differential pulse voltammetry (DPV) and chronoamperometry. The sensor was prepared by modifying a glassy carbon (GC) electrode surface with a cobalt tetrasulphonated phthalocyanine (CoTSPc) immobilized in a p...
