我厂用沉淀法试制出了一种银-氯化银-氯化钾(饱和)参比电极,其结构如图1。它的特点是液接部为玻璃磨口,内部用海棉状的银-氯化银取代汞-氯化亚汞。其优点是重现性和稳定性优于甘汞电极,液接电位小,内阻低,无汞的污染,是一种完全新型的外参比电极,其性能指标如表1。由表1可看出: 1.电极的稳定性和重现性良好,没有明
I plant a precipitation test to produce a silver - silver chloride - potassium chloride (saturated) reference electrode, the structure shown in Figure 1. It features a liquid-spliced glass grind port and a sponge-like silver-silver chloride interior to replace mercury-mercurous chloride inside. Its advantages are reproducibility and stability better than calomel electrode, liquid pick-up potential, low internal resistance, mercury-free pollution, is a completely new external reference electrode, its performance indicators in Table 1. Can be seen from Table 1: 1. The stability and reproducibility of the electrode is good, there is no clear
