Problems solved by technology

When the silver electrode is used and handled improperly, it will be oxidized, which will affect the accuracy of the experiment. At present, the commonly used operation is to rub the surface of the silver rod with fine sand, and then wash it with distilled water. Although the above operation can polish off the silver oxide, But it will be destructive to the surface of the silver electrode

Abstract

The invention relates to a silver electrode surface cleaning protective agent and a preparing method thereof. The silver electrode surface cleaning protective agent comprises, by weight, 35-55 parts of vegetable oil, 4-6 parts of propylgallate, 0.4-3 parts of a parabens corrosion remover, 70-100 parts of an emulgator, 35-45 parts of vitamin C, 10-20 parts of persimmon tannin and 150-200 parts of water. The silver electrode surface cleaning protective agent is obvious in silver electrode surface oxide removing effect, electrodes are not damaged, the antioxidant effect is obvious, and the silver electrode surface oxidizing rate can be effectively delayed.

Description

technical field [0001] The invention relates to a silver electrode surface cleaning and protecting agent and a preparation method thereof. Background technique [0002] In drug analysis experiments, silver electrodes are widely used. For example, in oxidation-reduction reactions, silver electrodes are used as positive electrodes; 216-type silver electrodes are used as indicator electrodes for measuring the concentration of silver ions and halogen ions, and are widely used in silver quantity analysis. Titrating. When the silver electrode is used and handled improperly, it will be oxidized, which will affect the accuracy of the experiment. At present, the commonly used operation is to rub the surface of the silver rod with fine sand, and then wash it with distilled water. Although the above operation can polish off the silver oxide, But it will be destructive to the surface of the silver electrode. In view of this, it is particularly important to invent a cleaning and protec...
