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 method for preparing a silver-based bactericide, in particular to a method for preparing a carbon-based high-valent silver molecular crystal battery. Background technique [0002] Silver has been known as a bactericide since 2000, and Ag 4 O 4 The nature, state, and structure of the product were discovered by synthesis in the 1970s. As a molecular-scale crystal battery, the water treatment method used for water treatment fungicides, fungicides, and algae inhibitors is the inventor of the topic of US Patent 5,211,855 . His patent description is 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 molecules are activated by the oxidizing agent sodium persulfate (potassium), they release electrons, which is equivalent to 6.4×10.19 watts / mol The electric power can effectively kill bacteria. In...
