C. Krantz-rulcker et al., Electronic tongues for environmental monitoring based on sensor arrays andpattern recognition: a review, ANALYT CHIM, 426(2), 2001, pp. 217-226
The use of sensor arrays and pattern recognition applied to the obtained si
gnal patterns for environmental monitoring are discussed in some detail. Di
fferent types of electronic tongues are described and evaluated for monitor
ing purposes. More specifically the performance of multielectrode arrays us
ed for voltammetric analysis of aqueous samples is described. It is, e.g. s
hown how such an 'electronic tongue' can be used to monitor the quality of
water in a production plant for drinking water. It is pointed out that the
concepts of 'electronic noses' and 'electronic tongues' often predict a qua
lity of a sample rather than giving exact information about concentrations
of individual species. (C) 2001 Elsevier Science B.V. All rights reserved.
