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.
