Embodiment 1

[0027] This example prepares anthraquinone-2-sodium sulfonate / graphene oxide composite photocatalytic bactericide according to the following steps:

[0028] Disperse 0.0030g sheet-layer graphene oxide (GO) in 4mL deionized water, and disperse evenly by ultrasonication for 30min to obtain a graphene oxide dispersion; add 0.0030g anthraquinone-2-sodium sulfonate (AQS) to the graphite oxide dispersion , and then ultrasonically dispersed for 8 hours to obtain a composite solution; the composite solution was centrifuged and washed with deionized water, and then freeze-dried at -50°C for 24 hours to obtain anthraquinone-2-sodium sulfonate / graphene oxide composite photocatalytic Fungicide (AQS-GO)

[0029] figure 1 GO prepared for this example ( figure 1 a) and AQS-GO ( figure 1 b) Transmission electron microscope (TEM) image. From figure 1 As can be seen in a, GO has a wrinkled surface and a sheet structure; from figure 1 It can be seen in b that AQS-GO also has a wrinkled sur...

Abstract

The invention discloses an anthraquinone-2-sodium sulfonate / graphene oxide composite photocatalytic bactericide and its preparation method and application. The composite photocatalytic bactericide is loaded with anthraquinone-2 on the surface of sheet graphene oxide ‑Sodium sulfonate. The composite photocatalytic bactericide of the present invention has high-efficiency photocatalytic bactericidal performance, has high-efficiency killing effect on harmful microorganisms in water bodies, and will have good application prospects in the fields of water body purification and the like.

Description

technical field [0001] The invention belongs to the field of photocatalysis, and in particular relates to an anthraquinone-2-sodium sulfonate / graphene oxide composite photocatalytic bactericide and a preparation method thereof. Background technique [0002] Water pollution brought by industrial development has increasingly become one of the serious environmental threats. There are various pollutants in water, including microorganisms, metal ions, organic matter, dyes, etc. Microbial pollution is a serious environmental problem. A variety of bacteria can cause various infectious diseases, threatening human health and economic development. The research on non-antibiotic antibacterial substances has therefore become a scientific hotspot in recent years, and the research and development of nano-antibacterial materials is considered to be the most promising strategy to overcome the problem of bacterial drug resistance and has practical application prospects. This is mainly due t...
