The maximum dissolved oxygen uptake rate is 19.28 mg L −1 h −1. Besides, the dissolved oxygen content decreases to 9.13 mg L −1 at the 45 min, which is lower than the saturated dissolved oxygen in the air (10.72 mg L −1). The other two MEAs with Pd and Pt as the cathode catalysts take around 60 min to reduce to the value.

AN ELECTROCHEMICAL OXYGEN METER. Full Record Other Related Research Abstract. A meter based on the galvanic cell was developed to enable traces of oxygen ln gases to be determined. The Instrument consists of four main partsa the galvanic cell, the electrolytic cell, the flowrate indicator, and the control unit. (M.C.G.)

Jun 18, 2018 · In an electrochemical DO sensor, dissolved oxygen diffuses from the sample across an oxygen permeable membrane and into the sensor. Once inside the sensor, the oxygen undergoes a chemical reduction reaction, which produces an electrical signal. This signal can be read by a dissolved oxygen instrument. Polarographic vs. galvanic DO sensors:

oxygen analyzer (Orbisphere 2713) and a pH-meter to the drain. 2.2. Deoxygenation method In all experiments the oxygen-rich water flowed down- wards in the cathodepartment (Fig. 3). The water flow was 2gs -1 (= 2mls 1). The cell voltage was adjusted to about 2.0 V. Oxygen molecules were reduced when they con-

For more negatively reduced metals, O2 reduction interferes with stripping analysis hence, most electroanalysis techniques rely on pretreatments to remove dissolved oxygen (DO). Current strategies for portable DO removal offer limited practicality, because of theirplexity, and often cause inadvertent sample alterations.
