摘要：

The paper describes the assembly and functioning of the microvoltammetric cell described in Part 1, with a hollow Fiber Supported Liquid Membrane (HFSLM), for trace metal analysis. Membrane stability, working-electrode behavior, mercury-film lifetime inside the HFSLM, hydrodynamic conditions, as well as transport kinetics of the metal through the SLM have been studied in detail. System calibrations have been performed in the range 5-120 nM Pb(II). The reproducibility and sensitivity of the whole microsystem is discussed as well as limitations and possible improvements.
