摘要：

The convenience of using polystyrene as material for voltammetric cells in the determination of Zn, Cd, Pb, and Cu was studied by differential pulse anodic stripping voltammetry. Cells of glass, PTFE Teflon, colorless polystyrene, and white polystyrene were compared. Polystyrene seems to be more suitable than PTFE Teflon or glass, especially at pH > 6, in 0.01 mol L(-1) KNO3 medium. In 0.5 mol L(-1) NaCl medium, differences between PTFE Teflon and polystyrene are not so important. However, the, use of polystyrene cells seems especially appropriate for measurements of Pb(II) and Cu(II).
