摘要：

A kind of integrated electronic tongue device has been developed, which includes a multiple light-addressable potentiometric sensor (MLAPS) and two groups of electrochemical electrodes. MLAPS is based on chalcogenide thin film for the simultaneous detection of Fe(III) and Cr(VI) ions while two groups of electrochemical electrodes, respectively, detect other heavy metals using stripping voltammetry (SV) including anodic and cathode stripping voltammetry. The methods are more convenient for the simultaneous detection of heavy metal in wastewater or seawater and can improve the detection speed and measurement accuracy to many heavy metals. Accordingly a kind of potable electronic tongue instrument to work on-line is also developed. (C) 2005 Elsevier B.V. All rights reserved.
