Embodiment 1

[0035] An electrochemical method for detecting polycyclic aromatic hydrocarbon anthracene, using the probe Alizarin Red (ARS) to modify the mesoporous material SBA15 electrochemically modified electrode, the modified electrode is prepared from the mesoporous material ARS-SBA15 and glassy carbon electrode, used for Detection of anthracene content in aqueous solution.

[0036] 1 Synthesis of mesoporous material SBA15: For the synthesis of SBA15, dissolve 4g Pluronic P123 in 30g deionized water, add 120g 2mol / L HCl, stir at 40°C to obtain a transparent solution, add 8.5g TEOS, and keep stirring at 40°C for 20h. Then continue aging at 100°C for 2-3 days, filter, wash and dry. Finally, the temperature was raised to 500°C at a rate of 1°C / min, and the SBA15 sample was obtained after calcination for 4-6 hours.

[0037] 2 Alizarin red probe (ARS) modified mesoporous material (SBA15), the steps are as follows: weigh 0.5g of ARS and dissolve it in an appropriate amount of dry DMF, add ...

Abstract

The invention relates to the technical field of anthracene analysis and determination of polycyclic aromatic hydrocarbons, in particular to an electrochemical method for modifying mesoporous materials using alizarin red as a probe and using it for quantitative detection and determination of anthracene content in water systems. The functional modified electrode using the probe to modify the mesoporous material has the advantages of simple and convenient material synthesis, easy fabrication of the modified electrode, low material price, easy renewal of the electrode, good reproducibility, non-toxicity, and no pollution to the environment, and the determination method is effective The interference of coexisting substances is reduced, the selectivity is good, and the sensitivity is high.

Description

technical field [0001] The invention relates to the technical field of anthracene analysis and determination of polycyclic aromatic hydrocarbons, in particular to an electrochemical method for modifying mesoporous materials using alizarin red as a probe and quantitatively detecting the anthracene content in a water system. Background technique [0002] As coal and petroleum are widely used in industrial production, transportation and daily life, the resulting polycyclic aromatic hydrocarbons have strong teratogenicity, carcinogenicity and mutagenicity, so they have become organic pollutants of common concern to all countries in the world. Anthracene widely exists in the wastewater discharged from the production of textiles, pharmaceuticals, papermaking, dyes and other industries, and has serious toxic effects on humans, animals, and plants. s concern. [0003] With the development of science and technology, various methods and instruments for detecting aromatic hydrocarbons...
