摘要

Main observation and conclusion We report here a chemical nose utilizing the nonspecificity of a hemicyanine dye(probe P)containing three acetates and one depro-tonatable phenol groups.Unlike conventional pattern-based recognition that requires a combination of different probes,probe P alone is able to differentiate 9 different metals,generating distinctive absorption spectra and various patterns upon principle com-ponent analysis(PCA).River water samples and commercial mineral water samples were evaluated by the probe and were success-fully distinguished.
