Embodiment Construction

[0030] The present invention will be further described with examples below in conjunction with the accompanying drawings and specific embodiments, but is not limited thereto.

[0031] 1. Process for preparing flower-shaped nickel metal-organic framework nanomaterials:

[0032] Weigh 0.096g Ni(NO 3 ) 2 •6H 2 O and 0.166g terephthalic acid (C 8 h 6 o 4 ) was dissolved in dimethylformamide (DMF) to obtain a mixed solution I.

[0033] Accurately prepare 2 mL of 0.4 M NaOH aqueous solution, and then slowly drop into the mixed solution I to obtain the mixed solution II, which is stirred at room temperature for 1 hour, and then hydrothermally reacted at 100°C for 8 hours. The obtained light green precipitate was washed with DMF and ethanol three times and then dried to obtain a flower-shaped nickel metal-organic framework nanomaterial.

[0034] Above Ni(NO 3 ) 2 •6H 2 O can also use NiSO 4 •H 2 O or Ni(CH 3 COO) 2 • 4H 2 O alternative.

[0035] The above NaOH aqueous ...

Description

technical field [0001] The invention belongs to the technical field of preparation of ascorbic acid sensors. Background technique [0002] Ascorbic acid is an essential vitamin and an antioxidant that improves the body's immunity and responsiveness. It is a naturally occurring organic compound with antioxidant properties. It is one of the important vitamins for maintaining normal physiological functions of the body. It is widely found in fresh fruits, juices and green leafy vegetables. It participates in a series of metabolism and redox reactions in the body, and also helps to synthesize intercellular substances such as collagen and mucopolysaccharides. It is also indispensable in the synthesis of adrenal cortex hormones and redox in the body. The lack of ascorbic acid in the human body will lead to scurvy Therefore, the quantitative analysis of ascorbic acid is of great significance in the fields of medicine and food. [0003] At present, the determination methods of asco...
