摘要：
The determination of trace elements such as Zn, Cd, Pb, Cu, Ni, Co, TI, Bi and Sn by potentiometric stripping analysis (PSA) in various matrices is described. With natural water samples only simple acidification to a pH of about 2 is sufficient to liberate the trace elements. In more complex matrices like waste waters, whole blood or other liquid samples the pH, time and deposition potential play an important role for the liberation of some trace elements. The data of interlaboratory comparisons about the determination of lead in whole blood and wine samples by PSA after simple sample preparation are presented.
