Problems solved by technology

This method is time-consuming and laborious, and cannot meet the requirements of rapid detection of aluminum content, and the accuracy and sensitivity are not high. This method can only measure the approximate range of aluminum content.
In addition, the sensitivity of UV spectrophotometer is not as good as that of fluorescence. For samples with low aluminum content, UV-visible light may not be able to detect

Embodiment

[0021] In this embodiment, 2-hydroxyl-1-naphthaldehyde semicarbazone is synthesized according to the following synthetic route:

[0022]

[0023] The specific process is:

[0024] Place the 250mL three-necked flask equipped with a thermometer, dropping funnel and reflux condenser in an electronic constant temperature water bath, add 30mL glacial acetic acid, add 22.2g (0.156mol) 2-naphthol and 3.8g (0.170mol) while stirring. mol) hexamethylenetetramine, stirred for 20 min until dissolved, raised the temperature to 90°C, added 33mL of concentrated sulfuric acid within 1h, and stirred at 96°C for 2.5h.

[0025] After the reaction was finished, cool to room temperature, and pour the above-mentioned reaction material into a beaker containing 100 mL of water under stirring. Control the temperature of the solution in the beaker not to exceed 30°C, and then add 200mL of water. Stir for 1 h, cool to room temperature, and let stand for 24 h to allow 2-hydroxy-1-naphthaldehyde to p...

Abstract

The invention relates to a probe for detecting aluminum ion, a preparation method and a kit including the probe and belongs to the technical field of chemistry. The probe for detecting aluminum ion, 2-hydroxyl-1-naphthaldehyde semicarbazone, is a naphthaldehyde-type Schiff base derivative which has a specific response to Al<3+>. An experiment proves that the compound has a good recognition capability on the Al<3+> in a Tris-HCl buffer solution with a pH value being 6.0 while interference of other anions and cations and amino acids on the detection of the Al<3+> is almost avoided. The probe is advantaged by being high in sensitivity and specificity.

Description

technical field [0001] The invention relates to a probe for detecting metals, a preparation method and a kit containing the probe, which belong to the technical field of chemistry. Background technique [0002] Aluminum is not an essential trace element for the human body, so excessive intake of aluminum is harmful to the human body. When the content of aluminum in the human body is too high, it will affect the absorption of phosphorus. Insoluble aluminum phosphate is formed in the intestinal tract and excreted with feces, and phosphorus deficiency affects calcium absorption (not enough calcium phosphate is produced), which can lead to osteoporosis and fractures. In recent years, it has been found that the appearance of Alzheimer's disease is also related to excessive intake of aluminum. Consumption of foods containing aluminum additives is one of the main sources of aluminum intake for people. Excessive aluminum in the body has adverse effects on the central nervous syst...
