Nanosilver solution is a nanomaterial with excellent antibacterial properties, which has wide application prospects in medicine, health, food, and other fields. Many manufacturers are actively developing and producing nanosilver solutions to meet the market demand. At present, the main production methods of nanosilver solution include chemical reduction, electrochemical, microemulsion, and so on.
1. Chemical reduction method
Chemical reduction is one of the most common methods for preparing nanosilver solutions. The method is to obtain nano silver particles by reducing silver ions and dispersing them in a solvent to form a nano silver solution. Commonly used reducing agents include sodium borohydride, ascorbic acid, formaldehyde, etc. The type and concentration of the reducing agent, reaction temperature, reaction time, and other conditions will affect the size and shape of silver nanoparticles and the performance of silver nanoparticles.
The advantage of the chemical reduction method is that the preparation process is relatively simple, easy to control, and suitable for large-scale production. However, the disadvantage of this method is that the residue of the reducing agent in the nanosilver solution will affect its antibacterial performance, and the waste solution can easily cause environmental pollution.
2. Electrochemical method
The electrochemical method is another common method for preparing nanosilver solutions. The method is to insert a silver electrode into an electrolyte containing silver ions, and an electrolytic reaction is carried out under certain voltage and current conditions to obtain nano silver particles. The composition of electrolyte and electrolytic conditions affect the size and shape of silver nanoparticles.
The advantage of the electrochemical method is that nanosilver particles can be obtained directly on the electrode without adding reducing agents, avoiding the influence of residues. However, the disadvantage of this method is that hydrogen will be generated during the electrolysis process, which is easy to cause safety problems such as explosions, and the waste liquid also needs to be properly disposed of.
3. Microemulsion method
The microemulsion method is a new method for preparing nanosilver solutions. The method is to mix the oil phase, surfactant, organic solvent, and so on to make a microemulsion, and then add the silver salt solution into the reaction to get nano silver particles. The microemulsion's composition, properties, and reaction conditions affect the size and shape of silver nanoparticles.
The advantages of the microemulsion method are that silver nanoparticles with small particle sizes and uniform distribution can be prepared, and the microemulsion system has good stability and dispersion. However, the disadvantage of this method is that the preparation process is relatively complex and requires a large number of organic solvents, which is easy to cause environmental pollution.
To sum up, different production methods of nanosilver solutions have their advantages and disadvantages, and it is necessary to choose the appropriate method for production according to the actual demand. At the same time, the production process needs to pay attention to environmental protection and safety issues and reasonable treatment of waste liquid and waste to ensure that the production process will not cause adverse effects on the environment.
Second,the production technology of nanosilver solutions has been continuously developed and improved. The chemical reduction, electrochemical, microemulsion, and other production methods have been developed and improved to improve the nanosilver solution's production efficiency and quality. At the same time, researchers are still exploring new production methods and processes to further reduce costs, improve efficiency and quality, and lay a solid foundation for the wide application of nanosilver solutions.
