Embodiment Construction

[0015] Below in conjunction with embodiment, the present invention is further described; Following embodiment is illustrative, not limiting, can not limit protection scope of the present invention with following embodiment.

[0016] The invention combines the surface molecular imprinting technology and the sol-gel technology to imprint the amine functional group on the surface of the silicon ball, thereby synthesizing the functional material with high selective adsorption for Sudan Red I. Its specific embodiment is:

[0017] 1. Add 14mL of acetonitrile, 0.5g of Sudan Red I, 1.8mL of 3-aminopropyltriethoxysilane containing bifunctional groups and 0.4g of silicon spheres activated by methanesulfonic acid aqueous solution into a 100ml three-path bottle in sequence , Stir the reaction under reflux for 35 minutes, then add 1.8mL tetraethoxysilane and 1.2mL 0.1mol L -1 acetic acid, incubate at 60°C for 9 hours.

[0018] 2. Filter the above product through ethanol and age it at 100...

Abstract

The invention relates to a synthetic method of the sudan red I adsorption functional material, the major technique characteristic is that taking the sudan red I as the template member, the three-amino propyl orthoformate silicon alkyl which contains the double function group as the function monomer, the activation silicon ball as the carrier, using the technology of superficial member signature and the sol-gelatin method to synthesize the sudan red I adsorption functional material. The invention has the low cost, the simple experiment operation and the reaction condition is easy to control, the prepared sudan red I adsorption functional material as the absorbent can be used in the solid phase extract and liquid phase chromatograph association, and suitable to online adsorption examine the trace amount of the sudan red I in each kind of food and seasoning.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a synthesis method of Sudan Red I adsorption functional material. Background technique [0002] Sudan I (Sudan I, 1-phenylazo-2-naphthol) is a synthetic azo industrial dye, mainly used for dyeing industrial products such as engine oil, wax and shoe polish. Foreign animal experiments have shown that Sudan Red I can cause cancer in mice, and further research shows that it also shows possible carcinogenic properties in human liver cells. Aniline, a metabolite of Sudan Red I in the body, can directly act on liver cells, causing toxic liver disease. Long-term intake of aniline can cause damage to the nervous system of the human body. The International Agency for Research on Cancer lists it as a third-class carcinogen. Although such substances lack sufficient evidence to directly cause human cancer, their potential carcinogenic danger is unquestionable, and if consumed in la...
