摘要： R.W.Cattrall等曾研制PVC膜CdCl42-离子选择电极,其线性响应范围10-1-10-4M,级差26-28mV。本文报道以三辛基十二烷基碘化铵与镉澳络阴离子形成的缔合物为电活性物的涂碳(PVC膜)CdBr42-离子选择电极的研究结果。

Abstract: Acoated-carbon (PVCmembrane) CdBr42-ion selective electrode based on the trioctyldodecyl-tetrabromocadmiumate (Ⅱ) ion pair is described. The electrode exhibited Nernstian response for cadmium (Ⅱ) in 1M NaBr solution with a slope of 31±1mV decade over the concentration range 10-1-10-6Mat 25.5℃.Other performance parameters of the electrode and its application have also been reported.
