Beinrohr, M. Németh, P. Tschöpel, G. Tölg] Summary: Flow-through electrochemical cells with porous working electrodes made of crushed reticulated vitreous carbon and plated with mercury were used for absolute analysis of trace amounts of lead by anodic stripping coulometry with collection (ASCWC) in a flow system. The role of mercury coating, flow rate and pH were investigated. The coulombic content of the collection peak corresponded to the theoretical values calculated by Faraday's law in a concentration range from about 10−9 to 10−6 mol/l. The relative error and the relative standard deviation was +0.15% and 0.8%, respectively for 2×10−6 mol/l analyte concentration. The absolute detection limit (3 s) was 0.1 ng of Pb, the linear response range 7×104. Springer-Verlag, 1992 Beinrohr E.
