Problems solved by technology

Since the viscera of abalone is not an edible resource, it cannot be used as a food raw material for further processing
At present, most abalone viscera are treated as waste, and the utilization rate of processing is extremely low, which not only causes waste of resources, but also easily causes environmental pollution
At present, there is no report on the preparation of nano-silver sol using the degradation products of abalone viscera as reducing agent and stabilizer

Embodiment 1

[0043] Under stirring conditions, the degradation product of abalone viscera (protease degradation product of abalone viscera) and silver nitrate crystals were gradually added into deionized water to make it completely dissolved. The concentration is 1.0×10 -2 mol / L. The above solution was placed in a microwave reactor, the microwave power was adjusted to 700W, the microwave temperature was 60°C, and after microwave reaction for 30 minutes, a stable dispersed nano-silver sol was obtained.

Embodiment 2

[0045] Under stirring conditions, the degradation products of abalone viscera (abalone viscera acid hydrolyzate) and silver nitrate crystals were gradually added into deionized water to completely dissolve them. The concentration is 5.0×10 -2 mol / L. The above solution was placed in a microwave reactor, the microwave power was adjusted to 1000W, the microwave temperature was 70°C, and after 10 minutes of microwave reaction, the dispersed and stable nano-silver sol was obtained.

Embodiment 3

[0047] Under stirring conditions, the abalone viscera degradation product (alkaline viscera hydrolyzate) and silver nitrate crystals were gradually added to deionized water to dissolve them completely. The concentration is 5.0×10 -1 mol / L. After the above solution was placed in a 60° C. water bath and heated for 120 minutes, a stable dispersed nano-silver sol was obtained.

Abstract

The invention provides an environment-friendly fast nano silver sol preparation method implemented through abalone viscus degradation products, and belongs to the technical field of nano-machining. The preparation method of nano silver sol comprises the steps that the abalone viscus degradation products and silver nitrate are mixed and dissolved in a water-phase system, and the nano silver sol which is even in dispersion and good in stability is prepared through microwave heating, hot bath, oil bath or ultraviolet radiation. The preparation method is simple, safe and fast, and a green, environment-friendly and fast method is provided for preparation of the nano silver sol. Abalone viscera belong to by-products of the abalone processing industry and are reproducible biological resources. A new method is provided for synthesis of the nano silver sol, and meanwhile, high-value application of the abalone viscera is achieved.

Description

technical field [0001] The invention belongs to the field of nanotechnology, and in particular relates to a green and rapid preparation method of nano-silver sol from degradation products of abalone viscera. Background technique [0002] Nano-silver sol is widely used in the fields of clothing, food, paint, cosmetics, medical equipment, plastics and textiles due to its high efficiency, wide range of antibacterial properties, and no drug resistance. In related technologies, chemical reagents such as hydrazine hydrate and sodium borohydride are used as reducing agents to react with silver nitrate to prepare nano-silver sol. However, chemical reagents such as hydrazine hydrate and sodium borohydride have certain biological toxicity, and their residues not only have a negative impact on the environment, but also affect the biological safety of nano-silver sol, which greatly limits its application in the fields of medicine and biology. . [0003] In order to overcome the biolog...
