The application discloses a silver sulfate silver ion slow-release compound, a preparation method and application thereof, and belongs to the field of chemical materials and slow-release technology. The preparation method of the silver sulfate silver ion slow-release compound selects modified porous materials as a slow-release carrier, precisely loads silver sulfate through impregnation or co-precipitation, constructs a gradient density regulation layer by using a high molecular polymer, and can introduce an environmental response additive to dynamically adjust the silver ion release rate. The application solves the problems that the silver ion release of the existing silver sulfate solution is too fast, the concentration fluctuation is large, and the silver ion release cannot adapt to complex scene requirements, has the characteristics of strong release controllability, wide adaptation range and low cost, and is suitable for various fields such as medical antibiosis and water purification.

This application relates to the field of environmental monitoring and water quality analysis technology, and in particular to a mixed reagent, test reagent tube, and digestion method for COD detection of petrochemical wastewater. The components, by mass percentage, are: sulfuric acid 75.0–90.0%, potassium dichromate 0.5–1.0%, silver sulfate 1.0–2.7%, scandium sulfate 0.01–0.07‰, potassium hydrogen phthalate 0.1–0.25‰, glucose 0.1–0.25‰, with the remainder being pure water; the mixed reagent does not contain mercuric sulfate. This application enables mercury-free and highly efficient digestion of high-salt, high-organic-content petrochemical wastewater, improves the oxidation efficiency of benzene compounds and polycyclic aromatic hydrocarbons, reduces the detection limit to below 5 mg / L, and the wastewater is easy to treat, combining high accuracy with environmental friendliness.
