Problems solved by technology

However, the simple use of redox mediators can lead to "secondary pollution" of water bodies. Grafting and immobilizing redox mediators on carriers is an effective method, and can be recycled and reused. The currently reported carriers include polymer membranes. (Publication No. CN103936146B), filler (Publication No. CN110092389A) and other methods, but still have the problems of low grafting efficiency and poor reusable effect

Embodiment 1

[0039] Place the reactor in an environment of 0-5°C, add 1-aminoanthraquinone and fluorosilicon polymer A at a molar ratio of 1.9:1, and then add tetrahydrofuran and fluorosilicon polymer A which are 10 times the weight of fluorosilicon polymer A 2% 1-methylimidazole, stirred and reacted for 6 hours, then placed at 40°C and stirred for 2 hours, and THF was removed to obtain an anthraquinone-containing fluorosilicon compound, denoted as F-1.

Embodiment 2

[0041] Place the reactor in an environment of 0-5°C, add 2-aminoanthraquinone and fluorosilicon polymer B at a molar ratio of 2:1, and then add tetrahydrofuran and fluorosilicon polymer B that are 15 times the weight of fluorosilicon polymer B 2% 2-methylimidazole, stirred and reacted for 3 hours, then placed at 30° C. and stirred for 5 hours, removed tetrahydrofuran, and obtained anthraquinone-containing fluorosilicon compound, denoted as F-2.

Embodiment 3

[0043]Place the reactor in an environment of 0-5°C, add 1-amino-2-methylanthraquinone, fluorosilicon polymer C and 2-phenylimidazole by weight of 2% by weight of fluorosilicon polymer C at a molar ratio of 4:1 , and then added butyl acetate 15 times the weight of fluorosilicon polymer C, stirred for 3 hours, then placed at 30°C and stirred for 5 hours, removed butyl acetate, and obtained anthraquinone-containing fluorosilicon compound, denoted as F-3.

Abstract

The invention belongs to the technical field of wastewater treatment, and relates to a modified silicone rubber composition, a textile fabric and application thereof. The modified silicone rubber composition comprises silicone rubber and an anthraquinone-containing fluorosilicone compound, the weight ratio of the silicone rubber to the anthraquinone-containing fluorosilicone compound is 100: 0.05-3, and the anthraquinone-containing fluorosilicone compound is obtained by a reaction between an anthraquinone compound and a fluorosilicone polymer. The textile fabric prepared from the modified silicone rubber composition has a good effect of promoting the microbial degradation of azo dyes and nitrates.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and relates to a modified silicone rubber composition, textiles and applications thereof. Background technique [0002] Extensive use of azo dyes and excessive use of nitrates pose a huge potential threat to the environment and human health. How to effectively remove these pollutants has become an urgent matter. There are three main treatment methods: chemical method, physical method and biological method. The anaerobic microbial degradation in the biological method has great advantages and has become the main application method. Redox mediators, such as anthraquinone compounds, can increase the degradation rate of anaerobic microorganisms by more than 1 order of magnitude. However, the simple use of redox mediators can lead to "secondary pollution" of water bodies. Grafting and immobilizing redox mediators on carriers is an effective method, and can be recycled and reused. The cu...
