应用固体汞膜电极测定矿石中的铅

The Determination of leed in the Ore By Means of solid Mercury Membrane

固体汞膜电极具有灵敏度高，背景电流小，测定浓度范围宽等优点，连续记录１６个图形最大相对误差在４％以内，电极工作一个月以后，又连续记录１４个图形，最大相对误差在３．５％．电极的稳定性较好．选择适当的底液后，能获得良好的测定结果，因此汞膜电极是可以用来代替滴汞电极极谱测定铅．

The electrode of solid mercury membrane is favourably characterized with high sensitivity. low back-ground current, wide scope of determined consistency. The maximum relative error of 16 continuously recorded figures is within 4%. With the electrade having workeed for one month, 14 figures is continuously recorded again, obtuining a maximmum relative error of 3 5% that indicates beffer electrode stability. While a proper bottom liguid being selected, a fine fested result is expected to arrive at the conclusion that there is a fedsibility to determine the lead in place of the polarogram of drop mercury.
