Electrochemical detection of SO2 in a hydroxyl ...

Using ionic liquids (ILs) as electrolytes in developing electrochemical sensors for SO 2 detection is of much interest. We compared the electrochemical behaviors of SO 2 in choline chloride–ethylene glycol-based deep eutectic solvent (ChCl–EG-based DES), 1-(3-hydroxypropyl)-3-methylimidazolium tetrafluoroboride ([C 3 OHmim]BF 4), and [C 3 OHmim] BF 4 + monoethanolamine (MEA) (:1 in ...

Electrochemical Sensor for the Detection of SO2 in the Low ...

The development of an improved electrochemical sensor for the detection of concentrations of atmospheric sulfur dioxide in the low-ppb range is described. The sensor is based on a porous Au−solid polymer electrolyte sensing electrode which is in direct contact with the gas-containing atmosphere. Although the cell design is not new, it is demonstrated that, by careful selection of component ...

Best Sulphur Dioxide (SO2) Gas Detector (Top Pick ...

· A sulphur dioxide gas detector is composed of electronics and an SO2 sensor. The gas sensor converts the detected gas concentration to an electronic signal for analysis by the onboard microprocessor. After receiving the electrical signal, the processor displays the SO2 concentration reading. If the measurement exceeds the pre-set SO2 alarm value, the alarms are triggered.
