Abstract

The invention discloses aluminum ion detection test paper as well as a preparation method and a use method of the aluminum ion detection test paper. The test paper is prepared in the steps of infiltrating the filter paper into a steeping liquid, and taking out and drying the filter paper, wherein the steeping liquid comprises a steeping liquid I and a steeping liquid II, the steeping liquid I is prepared by dissolving and uniformly mixing 0.1-0.6g of chrome azurol S into 100ml of distilled water, and the steeping liquid II is prepared by sequentially dissolving and uniformly mixing 2g of phenanthroline into 100ml of distilled water. According to the test paper, the chrome azurol S is taken as a color developing agent and is used in a manner of being matched with an activating agent prepared by uniformly mixing 12.64mL of sodium hydrogen phosphate solution with the concentration of 0.2mol / L with 7.37mL of citric acid solution with the concentration of 0.1mol / L, the preparation is simple, the cost is low, the use is convenient, the environmental pollution is avoided, and the environment is beneficially protected; the aluminum ion detection test paper is wide in test range, does not need to be operated by professional people and is particularly suitable for the rapid field test of the aluminum content.

Description

technical field [0001] The invention relates to an aluminum ion detection technology, in particular to an aluminum ion detection test paper using chromazurin S as a color developing agent, a preparation method and a use method thereof. Background technique [0002] With the improvement of people's health awareness and the in-depth research on aluminum toxicity, the intake of aluminum in human body has attracted worldwide attention. Studies have shown that aluminum directly acts on bone tissue, which can cause bone lesions; after the organism absorbs aluminum, most of it accumulates in the body, and when it reaches a certain concentration, it will interfere with the metabolism of phosphorus, leading to a variety of bone lesions; aluminum in the brain tissue Accumulation can cause central nervous system dysfunction, which may lead to senile dementia; in addition, aluminum can significantly reduce the content of norepinephrine, dopamine and 52 serotonin in the brain, resulting ...
