Embodiment 1
[0029] A kind of cyanide ion fluorescence detection test paper modified by pillar aromatic hydrocarbon, the specific preparation method is as follows:
[0030] 1) Oxidation of test paper: A quantitative filter paper was ultrasonically cleaned with THF, acetone, and purified water in sequence, 5 min each time, immersed in a 0.1 M sodium periodate aqueous solution, and immersed for 5 h at 40 °C in the dark, and 20 mL of ethyl acetate was added. Diol, continue to react for 1h, wash off excess ethylene glycol with water, and dry for use.
[0031] 2) Functionalization of column aromatics on the test paper: immerse the oxidized filter paper in 0.1M column aromatic THF solution, immerse the reaction at 50 °C for 10 h, then use THF and methanol to ultrasonically clean the filter paper in turn, and then immerse the cleaned filter paper in 0.5 M sodium borohydride methanol solution, immersed at 20 ° C for 1 h, ultrasonically cleaned with methanol, and dried for use.
[0032] 3) Fixatio...
Embodiment 2
[0035] A kind of cyanide ion fluorescence detection test paper modified by pillar aromatic hydrocarbon, the specific preparation method is as follows:
[0036] 1) Oxidation of test paper: The test paper is oxidized by the same method as step 1) in Example 1;
[0037] 2) Functionalization of column aromatics on the test paper: immerse the oxidized filter paper in 0.02M column aromatics dichloromethane / methanol (volume ratio 2:1) solution, react at 70°C for 15h, and ultrasonically clean the filter paper with dichloromethane and methanol. The cleaned filter paper was immersed in 0.1M sodium borohydride methanol solution, reacted at 30° C. for 3 h, ultrasonically cleaned with methanol, and dried for use.
[0038] 3) Fixation of the fluorescent indicator of the test paper: soak the filter paper functionalized with column aromatic hydrocarbons in 0.01M 10-methylacridine solution (the solvent is tetrahydrofuran), react at 30°C for 5 hours, ultrasonically clean with tetrahydrofuran, a...
