Embodiment 1

[0030] The specific preparation process of the present invention is as follows: 1. get 10 g of sucrose and dissolve it in 80 ml of deionized water, and transfer it to an autoclave. Then the autoclave was put into a drying oven and heated to 190 ° C for 2 hours. After the reaction was completed, it was naturally cooled to room temperature, and the product was washed several times with deionized water and ethanol, then dried in a drying oven, and heated to 80 ° C for 12 hours. When the drying oven is lowered to room temperature, the carbon microsphere chains are obtained.

[0031] ②Using the oil bath method, add 20 mg of the above-prepared carbon microsphere chains into 40 ml of deionized water, and sonicate for 30 minutes. 75 mg Ni(NO 3 ) 2 ·6H 2 O, 132.7 mg Mn(NO 3 ) 2 4H 2 O, 35 mg HMT and 7.2 mg TSC were dissolved in the above suspension and sonicated again for 15 minutes. Then it was put into an oil bath and continued magnetic stirring, heated to 90 ° C for 6 hours. ...

Abstract

The invention discloses a microsphere chain for detecting ascorbic acid, a preparation method and application thereof. The microsphere chain includes a carbon microsphere chain composed of carbon microspheres connected end to end, and a honeycomb NiMn uniformly coated on the carbon microsphere chain 2 o 4 Nanosheets. Its preparation method is: using hydrothermal method, using sucrose as raw material to prepare carbon microsphere chains; adopting oil bath method, using carbon microsphere chains as substrate, uniformly coating NiMn 2 o 4 Nanosheets. The method of the invention has simple process, mild reaction conditions, low preparation cost and good stability. As-prepared NiMn 2 o 4 The / C microsphere chain combines the advantages of material energy difference and inherent oxidase-like enzymes to play a synergistic effect, which can realize the highly sensitive and selective detection of ascorbic acid.

Description

technical field [0001] The invention relates to a microsphere chain for detecting ascorbic acid, a preparation method and application thereof, and belongs to the technical field of new composite materials. Background technique [0002] Ascorbic acid (AA), also known as vitamin C, plays an important role in maintaining biological health. It has many functions such as protecting cells from oxidative damage and preventing the development of scurvy, common cold, cancer, etc. However, since the amount of AA in the human body is very low, it is difficult to be detected. Currently, various methods have been developed to detect ascorbic acid, such as electrochemical methods, liquid chromatography methods, enzymatic methods, and fluorescence methods. But these methods require complex equipment and are expensive. [0003] The colorimetric sensing method for the detection of ascorbic acid not only solves the above problems, but also has the advantages of low cost, simplicity, visual...
