Embodiment 1
[0070] The preparation of nano silver ion modified carbon black antibacterial agent adopts the following method:
[0071] 1) A 2M aqueous solution of soluble silver salt is reacted with ammonia to form an alkaline aqueous solution of silver ammonia complex; wherein the molar ratio of the aqueous solution of soluble silver salt to ammonia is 1:10;
[0072] 2) Add carbon black to hydrogen peroxide solution, mix well and let it stand for 60 minutes, add it to the alkaline aqueous solution of silver ammonia complex prepared in step 1), carry out the reduction reaction, separate the precipitate and wash after the end, the brown-black solid is the nanometer Silver particles modified carbon nanotubes; the mass of carbon black is 0.5 times the mass of the silver ions; the molar amount of hydrogen peroxide is 2 times the molar mass of the silver ions.
