Aluminum is a silver-white metal, which can form an oxide film to prevent metal corrosion in humid air. Aluminum powder burns violently when heated in the air and emits a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, hardly soluble in water.

The long-term accumulation of aluminum in patients with renal failure will seriously threaten the patient's bones, brain, and nervous system. Since most of the aluminum is ingested through the diet and enters the body, it is targeted for different packaged beverages but with the same contents of beverages. Detection of aluminum content. Because aluminum is not easily absorbed by the gastrointestinal tract and people with normal metabolic functions, more than 90% of the aluminum consumed in the diet will be excreted through feces, urine and even sweat. Therefore, domestic food hygiene-related units have not clearly set the aluminum metal content of food. Normal range, but patients with renal failure with renal insufficiency cannot excrete aluminum and lead to aluminum poisoning. Therefore, we hope that this experiment can know the amount of aluminum metal in various types of packaged beverages, so as to make recommendations for patients to choose beverage packaging. The results show that under the same content, the aluminum content of aluminum canned beverages is significantly higher than that of bottled beverages, while the aluminum content of tea beverages is generally higher. As a common metal, aluminum is widely used. It has been identified as a food contamination and can be controlled because it can lead to loss of memory. The content of aluminum ions in aluminum canned beverages is related to the type of beverage, the length of storage time, and the brand.
The detection of aluminum ions has important physiological significance. CD BioScience offers a series of water-soluble high light stability probes (dye molecules) that are sensitive to aluminum ions (Al3+). Our probes are very bright and easy to use. The aluminum ion probe we provide is a unique fluorescent probe that has a higher selectivity for aluminum than other dissolved cations. It can detect and quantify dissolved aluminum (Al3+). It is an open-type fluorescence sensor. This means that the fluorescence of the solution increases with the increase of the dissolved aluminum concentration and can be easily excited in a wide wavelength range of 280-400 nm. In the presence of aluminum ions, the fluorescence emission is very strong around 420 nm.
