NOVELTY - Complex antibacterial gel comprises benzalkonium bromide or benzalkonium chloride and graphene oxide according to the mass ratio of 1-10:2-6. USE - The gel is used in preparing medicine or water treatment preparation having antibacterial effect (claimed). ADVANTAGE - The gel is prepared by simple process; comprises benzalkonium bromide and graphene oxide combined characteristic, which makes up the two itself at a certain concentration, which cannot be antibacterial and it is not easy to be recovered; and has anti-Gram-negative bacteria and Gram-positive bacteria activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing complex antibacterial gel comprising preparing benzalkonium bromide or benzalkonium chloride aqueous solution and preparing graphene oxide aqueous solution, quickly adding graphene oxide aqueous solution into benzalkonium bromide or benzalkonium chloride aqueous solution tom obtain brown benzalkonium bromide or benzalkonium chloride/graphene oxide antibacterial gel.
