✦ Synopsis
Disc and cyhnder nucroelectrodes were prepared from thm gold and platmum wnes and from carbon fibres by carefully heat seahng the wues or fibres into a polypropylene matnx The procedure IS particularly suitable for the preparation of mexpenslve, disposable mlcroelectrodes Mercury-coated carbon fibre electrodes, which could be used m hundreds of stnppmg voltammetrlc expenments without a slgmhcant decrease m performance, were prepared usmg ex situ mercury deposltlon Anod~c stnppmg results for copper, lead and mercury are dtscussed for both ex situ and m situ formed mercury-coated electrodes The ex situ prepared electrodes were employed to mvestlgate the posslbdlhes of canymg out anodic stnppmg voltammetrlc determmahons of copper m high-punty waters Keywor& Anodlc stripping voltammetry, Copper, Lead, Mercury, Waters
