Graphite raw material is made of graphite; graphite is made into graphite material, and then smelted, most of the graphite is dropped during smelting to become graphite powder, and then added to the smelting process to refine, the higher the graphite content, the higher the graphite powder content The higher it is, the graphite powder will be processed later; the mechanism is graphite oxidation.
There are two kinds of oxidation and reduction, and the oxide is silver. The reducing product is: silver nitrate; there is industrial manufacture, nitric acid and nitrous acid react to form silver salt. Nitric acid can also reduce silver to form silver salts. Nitrous acid is more toxic, and heavy metals account for the majority, so normal water will be filtered. However, with so many compounds, the laboratory has solutions, and the requirements are not high. Nitric acid produces silver nitrate, which is highly carcinogenic, but after slowly combining with human cells, the silver will be slowly excreted from the intestines and conducted from the nostrils, so there is no acute toxicity. The pictures and texts are from the Internet.
The common method used by 90% of the world’s water is to do oxidation precipitation containing silver nitrate in the pre-coagulation stage that is difficult to control directly. At this time, the silver nitrate in the water has reached (most) the hardness of water, which is too hard. Lead to human poisoning and fatal. However, since a large amount of silver sulfate participates in the reaction in the water after silver nitrate coagulation, excess silver sulfate will combine with calcium and magnesium ions in water to form precipitates such as calcium sulfate and magnesium sulfate that are insoluble in water. was left in the water, which was harder.
It may also be that you have been mixed with a large amount of coagulants such as barium sulfate, barium nitrate, and ferrous sulfate before drinking some unknown liquid to make it difficult to be dissolved by the human body and may cause toxicity and poisoning.
