Producing carbon-ceramic-material-based electrochemical sensor for determining dissolved oxygen and for environmental monitoring in wastewater treatment plants, involves synthesizing mixed silicon dioxide tin oxide by sol-gel process
NOVELTY – Carbon-ceramic-material-based electrochemical sensor production involves synthesizing mixed silicon dioxide tin (II) oxide by sol-gel process. The obtained mixed oxides are purified and dried and then mixed with manganese (II) oxide, where the obtained material is purified. The purified material is dried for preparing disc-shaped electrode. USE – Method for producing carbon-ceramic-material-based electrochemical sensor for determining dissolved oxygen and for environmental monitoring in wastewater treatment plants and controlling oxygen concentrations in industrial processes (claimed). ADVANTAGE – The method produces the carbon-ceramic-material-based electrochemical sensor with good performance, good mechanical strength, selective reproducibility, a long life span and a good detection limit of order of parts per billion (ppb). DESCRIPTION OF DRAWING(S) – The drawing shows a schematic representation of the carbon-ceramic-material-based electrochemical sensor production process. (Drawing includes non-English language text).
Main Application Field
