A kind of preparation method of silver-loaded activated carbon antibacterial fiber membrane

Abstract

The invention discloses a preparation method of silver-loaded activated carbon antibacterial fiber membrane, which comprises the following steps: Step 1) Preparation of antibacterial silver-loaded activated carbon: soak activated carbon in AgNO 3 In the solution, choose a deflocculant, dissolve in AgNO 3 solution, and then the glucose solution was slowly added dropwise to the AgNO 3 In the solution, heat it in a water bath and stir it magnetically, then filter the product, wash it with water, and remove glucose until the Ag+ is completely removed, then dry it in vacuum, and finally dry the product in a blast oven, then place it in a tube furnace at a high temperature of 500° in a nitrogen atmosphere Burn to obtain silver-loaded activated carbon; Step 2) Spinning solution preparation: dissolve polyacrylonitrile in a certain volume of N,N-dimethylformamide solution, heat, and magnetically stir to obtain spinning solution, and then Silver activated carbon is added to the spinning liquid, and after sealing, it is magnetically stirred for 8 hours to obtain an antibacterial spinning liquid; Step 3) Spinning: use an electrostatic spinning device for spinning, and the present invention makes the fiber membrane have better antibacterial properties.

Description

technical field [0001] The invention relates to a fiber membrane, in particular to a preparation method of a silver-loaded activated carbon antibacterial fiber membrane. Background technique [0002] Safe and reliable drinking water supply is of great significance to the protection of people's health and economic development. Water supply enterprises must implement the whole process management from water source to users, especially in the water supply stage of pipe network, to ensure that end users get safe and high-quality drinking water. Although the factory water has been chlorinated and disinfected, a large number of microorganisms have been killed, and even the pipe network water contains a certain amount of residual chlorine to continue to maintain the disinfection effect, the problem of a significant drop in the pass rate of bacteriological indicators in the water terminal will still occur. The latest research and industry application results show that conventional ch...

Problems solved by technology

The film-forming method of electrospinning to prepare fiber film is to form a Taylor cone at the nozzle by the spinning liquid in a high-voltage electric field, and the fiber filaments are stacked on the upper layer of the receiving device to form a film, with high porosity, large specific surface area of ​​the film, and high membrane pressure. Small size, large water flux, etc., but there is also the problem of poor mechanical properties of the membrane
