报导的晶体膜铅离子电极以PbS-Ag_2S及PbTe-Ag_2S作敏感膜的电极性能较佳。Majer等比较过硫、硒、碲化物制备电极的灵敏度。我们参照有关报导用碲化铅制备铅电极并与硫化铅作基质的电极比较,其可测下限相差似并不显著,且在通常条件下在氮气氛中烧结所得碲化物膜片,不易抛光得到致密镜面光洁的电极膜。而用价廉的PbS作基质较易加工制备。经研究改进制得的Ag_2S-PbS铅电极性能较好。本文报导有关该电极的制备及
The reported performance of electrodes with PbS-Ag 2 S and PbTe-Ag 2 S as the sensing film for the crystalline film lead ion electrode is better. Majer et al. Compared the sensitivity of electrodes prepared with sulfur, selenium, and telluride. We refer to the report about the use of lead telluride lead electrode preparation and lead sulfide matrix as compared with the electrode, the lower limit of detection of similar and not significant, and under normal conditions sintered in a nitrogen atmosphere obtained telluride membrane, not easy to polish Compact and smooth mirror electrode film. The inexpensive PbS matrix for easier preparation. The improved Ag 2 S-PbS lead electrode obtained by the research is better. This article reports on the preparation of the electrode and
