摘要：

A gold-fibre microelectrode is proposed for the determination of mercury in high-purity gallium arsenide by stripping analysis. The precision and accuracy were tested using mercury-spiked gallium arsenide samples and were found to be satisfactory for mercury contents higher than approximately 10 ppb. Both the precision and accuracy exceed those of the method applying a compact gold rotating disc electrode. De-aeration of the sample solution and its stirring during accumulation are unnecessary in the analyses with gold-fibre microelectrodes.
