Abstract

The invention discloses a making method of carbon-based high-valent silver molecular crystal battery, which comprises the following steps: dissolving silver nitrate into pure water; stirring; placing the active carbon in the silver nitrate solution; adsorbing; filtering; drying the active carbon; placing the potassium peroxodisulfate or sodium peroxodisulfate as oxidizer into distilled water; adding sodium hydroxide; diluting; heating; stirring to react with dried active carbon; insulating; filtering; washing four times through pure water; obtaining the product with Ag4O4 distributed evenly on the surface of active carbon; displaying stronger chemical adsorbing ability and chemical reactivity; reinforcing the purifying capacity of organic toxic and harmful material absorbed by active charcoal.

Description

technical field [0001] The invention relates to a preparation method of a silver-based bactericide, in particular to a preparation method of a carbon-based high-valent silver molecular crystal battery. Background technique [0002] Silver has been known as a fungicide for 2,000 years, and Ag 4 o 4 The nature, state and structure of the compound were only synthesized and discovered in the 1970s. The water treatment method used as a molecular-scale crystal battery for water treatment fungicides, fungicides, and algicides is the inventor of the US Patent 5211855 topic . His patent describes that each Ag 4 o 4 The molecule is described as a battery. Ag 4 o 4 In the molecular structure of the molecule, there are two trivalent silver ions and two monovalent silver ions. When the crystal molecule is activated by the oxidant sodium persulfate (potassium), they release electrons, which is equivalent to 6.4×10.19 W / M The electric power can effectively electrocute the bacteria....
