摘要：

A glassy carbon electrode (GCE) coated with Langmuir-Blodgett (LB) film of p-allylcalix[4]arene is described for simultaneous determination of traces of thallium and cadmium in environmental water. The LB film electrode in a 0.1 M KH2PO4 solution shows a linear voltammetric response in the range of 5-250 mu g l(-1) for thallium and 10-300 mu g l(-1) for cadmium. The detection limits of thallium(l) and cadmium(11) are estimated to be 1.0 mu g l(-1) (ca. 5.0 x 10(-9) M) and 2.2 mu g l(-1) (ca. 2.0 x 10(-8) M), respectively. Above all, the indium does not respond to this LB film electrode. (c) 2005 Elsevier B.V. All rights reserved.
