Embodiment 1

[0060] Cleaning of glass instruments such as reaction kettles and beakers: After preliminary brushing of the inner liner of the reaction kettle, etc. with a test tube brush, add ethanol to it, and ultrasonically clean it with an ultrasonic cleaner for 15 minutes. After taking it out, rinse it with deionized water, and dry it at 70 °C for use. .

[0061] Preparation of carbon quantum dots: After drying the collected C. japonicus, wash with ethanol and deionized water, dry at 70°C, grind the dried C. japonicus with a mortar, pass through a 60-mesh sieve, and weigh. 0.9g of the hollow lotus seed grass powder passed through a 60-mesh sieve was placed in a beaker, 40mL of ultrapure water was added to it, stirred with a glass rod, and then dispersed by ultrasonic for 5min. , and after suction filtration, the obtained carbon quantum dot solution is sealed and stored. It was named as CDs-0.9, and the pH was adjusted to 7.35 for use.

Embodiment 2

[0064] The same as in Example 1, the only difference is that the herb is used as the herb.

Embodiment 3-7

[0066] Same as Example 1, the only difference is that the pH is adjusted to: 6.9, 8.35, 8.85, 9.85, 10.35, respectively.

Abstract

The invention relates to a method for preparing calcite by induction of herbs, and belongs to the technical field of calcite synthesis. The method for preparing calcite by induction of herbs of the present invention includes: dispersing the powder of herbs in water, reacting at 200-220° C. for 6-12 hours, and separating solid-liquid to obtain a carbon quantum dot solution, the concentration of the carbon quantum dot solution being 20-25 g /L; mix the carbon quantum dot solution with the soluble calcium salt solution to obtain a mixed solution, then add the soluble carbonate solution at a rate of 4 to 5 mL/min to react for 1.9 to 2.2 h, filter, wash and dry to obtain a solution Calcite; wherein, the herb is at least one of Helicoverpa chinensis or Helianthus annuus; the pH of the carbon quantum dot solution is 6.9-10.35. The invention uses invasive plants to prepare calcite and improves its utilization value. The SEM image of the calcite prepared by the method of the present invention shows that it has a flower-shaped structure with square petals, and the purity is high.

Description

technical field [0001] The invention relates to a method for preparing calcite by induction of herbs, and belongs to the technical field of calcite synthesis. Background technique [0002] Calcite is a calcium carbonate mineral. Calcite has a variety of crystal shapes. You can get many square fragments by hitting calcite, hence the name Fangjie. The color of calcite varies depending on the impurities contained in it, such as light yellow, light red, brown-black, etc. when it contains iron and manganese, but generally it is mostly white or colorless. Colorless and transparent calcite is also called ice island stone. Such calcite has a wonderful feature, that is, through it, objects can be seen as double images. Therefore, iceland stone is an important optical material. Calcite has many uses in production and life. We know that limestone can form karst caves, and the stalactites and stalagmites in the caves are actually composed of calcite. [0003] The main component of t...
