研究了在阴离子交换全氟聚合物Tosflex汞膜电极（TMFE）上用阳极方波溶出伏安法测定锌离子（1-60 ng ml ~（-1））。检测限为0.1 ng ml（-1）Zn（II）。探讨了明胶、白蛋白、淀粉、樟脑、腐殖酸、Triton X-100、十二烷基硫酸钠（SDS）和十六烷基三甲基溴化铵（CTAB）等有机化合物的影响。结果表明，由于Tosflex膜的尺寸排阻和离子交换性能，TMFE比裸汞膜电极更能抵抗有机干扰。(C)2002 Elsevier Science B. V.保留所有权利。
The determination of zinc ion (1-60 ng ml(-1)) by anodic square-wave stripping voltammetry on an anion-exchange perfluorinated polymer Tosflex mercury film electrodes (TMFE) was evaluated. The detection limit was 0.1 ng ml(-1) Zn(II). The effect of various organic compounds (gelatin, albumin, starch, camphor, humic acid, Triton X-100, sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB)) is explored. The results indicate that due to the size-exclusion and ion-exchange properties of Tosflex film, the TMFE is considerably more resistant to organic interference than the bare mercury film electrode.
