Selection of piezosensors array for detection of volatile organic substances in water


The selection of piezosensors sensitive coatings for assessment the presence of anthropogenic volatile organic substances in equilibrium gas phase over the natural water has been made with the use of the measuring elements array and processing by principal components analysis. The piezosensors groups with similar characteristics for substance identification are determinated by the correlation between a piezosensors responses when detecting organic substances vapors. The array piezosensors is step-by-step optimized to identify the maximum number of studied organic compounds vapors. It has been shown the possibility of recognition of volatile organic compounds in their aqueous solutions and natural water using the optimized piezosensors array.
Key words: anthropogenic pollutants, water, detection, piezosensors, principal component analysis.
