Abstract

A poly-salicylic acid modified glassy-carbon electrode (PSAMGCE) was prepared by electro-polymerisation. The behaviour of copper on this electrode was investigated by anodic stripping voltammetry. The electrode is about 40 times more sensitive than the unmodified glassy-carbon electrode. It was applied to the determination of trace copper(II) in water, and shows a 96-106% recovery and a relative standard deviation of ca. 3%.
