极谱分析应用颇广,各种极谱仪与日趋完善的固体电极配合的效果已有不少报导,由于一般文献所列灵敏度和分辨度都是最佳条件下的数值,所以我们在稍高的浓度范围,以通常遇到的待测元素,将几种极谱仪与滴汞电极和玻璃碳汞膜电极配合得到的分析结果进行对比,并对极谱仪的研制提出一些浅见。我们选用的极谱仪为:1.脉冲极谱仪,2.MK—Ⅲ型方波极谱仪,3.示波方波极谱仪,4.JP—lA型示波极谱仪,5.883型普通极谱仪。一、分辨度图1用的是滴汞电极(本文各电极的m、t都
The use of polarographic analysis is quite wide, and the cooperation of various kinds of polarographs with increasingly sophisticated solid-state electrodes has been reported. Since the sensitivity and resolution listed in the general literature are values under the best conditions, we are at a slightly higher The results were compared with those of the mercury drop electrode and the glassy carbon mercury electrode by the commonly encountered test elements. Some suggestions on the development of the polarography instrument were also proposed. We use the polarography as follows: 1. Pulse polarography, 2.MK-Ⅲ square wave polarography, 3. Oscillography oscilloscope, 4.JP-lA oscilloscope, 5.883 Ordinary polarographic instrument. First, the resolution Figure 1 is the drop of mercury electrode (each electrode m, t are
