摘要：

A flow system for quantifying traces of heavy metals in brine by adsorptive stripping voltammetry (AdSV) is described. The system is developed and optimized for simplified, rapid sample processing using either linear scan or differential pulse waveforms. The advantages of the system include improved efficiency of sample preconcentration during the accumulation step, minimal sample pretreatment, simplified operation and sample deoxygenation, possible medium exchange between the accumulation and stripping steps, ready adaptility to automation and on-line monitoring. Minimum detection limits are less than 5-mu-g/l for all trace metals with precisions better than 7%.
