Embodiment 1

[0017] Embodiment 1: the concrete process and steps in the present embodiment are as follows:

[0018] a. Electrode casing preparation: take a 5 cm long glass tube (3 mm inner diameter), smooth both ends on sandpaper, clean it ultrasonically, dry it, and set it aside.

[0019] b. Preparation of montmorillonite-doped carbon paste electrode: Accurately weigh a certain amount of spectrally pure graphite powder and montmorillonite in an agate mortar according to an appropriate mass ratio, add a certain amount of paraffin oil drop by drop, Fully grind into a carbon paste; then put the carbon paste into the electrode casing obtained in the above steps, insert a copper rod as an electrical contact mandrel, compact and polish the electrode surface into a plane, then wipe off the excess carbon paste with filter paper, two Use after rinsing with water.

[0020] c. Simultaneously realize the electrochemical determination of bismuth coating and zinc ions by in-situ coating method: a t...

Abstract

The invention relates to a measurement method of the zinc ion content of honey, belonging to the technical field of electrochemical analysis and measurement. The method mainly comprises the following steps: doping montmorillonite in a carbon paste electrode, and using the in-situ coating method to prepare a bismuth film electrode and realize the electrochemical measurement of the zinc ion content of honey at the same time. The method is characterized by the simultaneous realization of the electrochemical measurement of the zinc ion content and the bismuth film through the in-situ coating method. Finally, the linear equation of the anodic stripping peak current of zinc ions and the concentration of zinc ions, which is obtained through the anodic stripping voltammetry, is used to measure the zinc ion content of honey. The method provided by invention is simple, the measurement is fast, the measurement sensitivity is high, and the repeatability and stability are good.

Description

technical field [0001] The invention relates to a new method for measuring zinc ion content in honey, which belongs to the technical field of electrochemical analysis and detection. Background technique [0002] Zinc is an essential trace element for the human body. It is distributed in all tissues of the human body and exists in various enzymes and insulin. It has extremely important physiological and biochemical functions in the human body and is known as the "flower of life". The level of zinc content has an important impact on people's intelligence, physical fitness and immune function. When the human body is deficient in zinc, it will cause loss of appetite, loss of sense of taste and smell, and slow wound healing, especially for children in the growth and development period. The main symptoms are growth retardation, pituitary gland regulation dysfunction, etc. However, excessive zinc intake can easily lead to the deficiency of other nutrients such as calcium, phosph...
