Embodiment 1
[0024] Take lycoris bulb samples, chop, dry and pulverize them to obtain lycoris bulb powder. Take 100 g of lycoris bulb powder and add it to 1 L of sulfuric acid solution with a volume solubility of 0.5%, extract in a water bath at 70°C for 3 hours, and ultrasonically treat for 30 minutes, 5000 rap Centrifuge under the condition of rotational speed of / min, obtain the crude extract of Lycoris after filtration. The crude Lycoris extract was adjusted to a pH value of 10 with 20% NaOH solution, and extracted 4 times with chloroform to obtain an extract. The pH of the extract was adjusted to 2 with 35% HCl solution. The ZSM-5 molecular sieve was calcined in a muffle furnace at 550° C. for 5 hours, and then loaded into a chromatography column to obtain a molecular sieve chromatography column. Put the extracted liquid after adjusting the pH value on the molecular sieve chromatography column, and carry out the bismuth potassium iodide reaction test on the effluent of the molecular ...
Embodiment 2
[0027] Take the amaryllis bulb sample, chop, dry, and pulverize it to obtain the amaryllis bulb fine powder, take 100 g of the amaryllis bulb fine powder and add it to 1.5 L of sulfuric acid solution with a volume solubility of 0.5%, extract it in a water bath for 5 hours, and ultrasonically treat it for 60 minutes. Centrifuge at 5000 rap / min, and filter to obtain crude Lycoris extract. The crude Lycoris extract was adjusted to a pH value of 11 with 20% NaOH solution, and extracted twice with chloroform to obtain an extract. The pH value of the extract was adjusted to 5 with HCl solution with a volume concentration of 38%. The X-type molecular sieve was calcined in a muffle furnace at 500° C. for 6 hours, and then loaded into a chromatographic column to obtain a molecular sieve chromatographic column. Put the extracted solution after adjusting the pH value on the molecular sieve chromatography column, and carry out the bismuth potassium iodide reaction test on the effluent of...
Embodiment 3
[0030] Take lycoris bulb samples, chop, dry and pulverize them to obtain lycoris bulb powder, take 100g of lycoris bulb powder and add it to 2L of sulfuric acid solution with a volume solubility of 0.8%, extract in a water bath for 4h, ultrasonically treat for 50min, 4000rap / min Centrifuge under the condition of rotating speed, and obtain the crude extract of Lycoris after filtering. The crude extract of Lycoris was adjusted to pH 9 with NaOH solution with a mass concentration of 20%, and extracted twice with chloroform to obtain an extract. The pH value of the extract was adjusted to 4 with HCl solution with a volume concentration of 36%. The Y-type molecular sieve was calcined in a muffle furnace at 550° C. for 5 hours, and then loaded into a chromatography column to obtain a molecular sieve chromatography column. Put the extracted solution after adjusting the pH value on the molecular sieve chromatography column, and carry out the bismuth potassium iodide reaction test on ...
