Embodiment 1

[0016] Step 1: Prepare silver phosphate nanopowder by injection precipitation method, dry the obtained product, and set aside. The specific preparation steps of silver phosphate nanopowder are: use silver nitrate solution and ammonia water to prepare silver ammonia solution and place it in beaker A, put the prepared phosphate source solution into beaker B, and add appropriate amount of The amount of surfactant polyethylene glycol 600 is 0.2% of the mass of the silver ammonia solution. Use a micro syringe with a volume range of 1 μL to add the silver ammonia solution in beaker A to beaker B containing the phosphate source solution. In B, a silver phosphate powder precipitate is generated, and the precipitate is collected after being centrifuged and washed, and dried to obtain a silver phosphate nanopowder. The second step: use the Erlenmeyer flask as a mold, dip it in the collodion solution, lift it, put it in the air to dry naturally, and peel it off to obtain semi-permeable m...

[0018] Step 1: Prepare silver phosphate nanopowder by injection precipitation method, dry the obtained product, and set aside. The specific preparation steps of silver phosphate nanopowder are: use silver nitrate solution and ammonia water to prepare silver ammonia solution and place it in beaker A, put the prepared phosphate source solution into beaker B, and add appropriate amount of Surfactant Triton X-100, its dosage is 0.2% of the mass of silver ammonia solution, using a micro-syringe with a volume range of 1 μL, add the silver ammonia solution in beaker A to beaker B containing the phosphate source solution. A silver phosphate powder precipitate is generated in beaker B, and the precipitate is collected after centrifugal washing and dried to obtain silver phosphate nanopowder. The second step: use the round-bottom flask as the mold, dip it in the collodion solution, pull it up and let it dry naturally in the air, peel it off to obtain semi-permeable membranes of differen...

Abstract

The invention relates to a novel renewable fish tank sterilizing and oxygen-releasing bag; the novel renewable fish tank sterilizing and oxygen-releasing bag is designed by taking a silver phosphate nano-powder material having high quantum yield as a main raw material; nano-silver and oxygen can be generated under the irradiation of visible light; with the assistance of swimming of fishes, water is sufficiently contacted with sterilization components, so that sterilization of water quality is realized; furthermore, oxygen can also be released; because of being constrained in a semipermeable membrane, nano-silver generated by photolysis cannot be lost in a fish tank; silver phosphate has the excellent characteristics of softening water quality, dispersing dirt, buffering an alkaline agent, preventing from caking and the like; silver phosphate can be reacted with amine substances in fish feces, so that phosphate is generated; and therefore, nutrients are provided for aquatic plants in the fish tank. After being used for a certain time, the sterilizing and oxygen-releasing bag can be taken out and is renewable in hydrogen peroxide, so that the sterilizing and oxygen-releasing function is obtained again.

Description

technical field [0001] The invention belongs to the field of applied inorganic chemistry, and in particular relates to a novel renewable fish tank sterilizing and oxygen releasing bag and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, more and more families are farming fish, and the demand for fungicides and oxygen evolution agents for fish tanks is increasing, and the requirements are also constantly improving. As a result, many interesting technologies have been developed. [0003] In terms of oxygen evolution agent research, Huang Zeping provided a chemical oxygen supply purification agent in the patent "Oxygen Supply Purifier for Aquatic Product Breeding" (application number: CN201110253976.6), its formula is (weight ratio): oxygen supply agent 10-70%; curing agent 0-30%; P value regulator 10-15%; de-ironizing agent 2-8%; stabilizer 0-2%; The water is neutral, which can provide effective suppor...
