Problems solved by technology

[0004] However, due to their geochemical properties, rare earth elements are rarely enriched to the extent that they can be mined economically, and the chemical properties of trivalent rare earth elements are very similar except scandium, so it is difficult to separate them.

Embodiment Construction

[0009] Add 10mL of diethylenetriamine and 100mL of absolute ethanol into a 250mL round-bottomed flask and mix them. After ultrasonication for 10min, add 5g of ACC-COOH and continue heating and stirring. Slowly add 3g of dicyclohexylcarbodiimide at 90°C within 3 minutes. Reflux for 12h. Cool and filter, wash the paint with 50mL of absolute ethanol, 30mL of dichloromethane, 50mL of absolute ethanol and 100mL of distilled water for several times, and dry it in vacuum at 70°C for 8h to obtain the product diethylenetriamine-modified activated carbon (AC-DETA). Weigh 2g of o-methoxybenzoic acid (OMBA) and dissolve it in 150mL of absolute ethanol, then add the prepared AC-DETA, and reflux at 90°C for 12h. The obtained product, the activated carbon modified with diethylenetriamine o-methoxybenzoate (AC-DETA-OMBA), was filtered, washed repeatedly with absolute ethanol and double-distilled water, and dried in vacuum at 60 °C. 6h.

Abstract

The invention belongs to a novel material and is an o-methoxybenzoic acid and diethylenetriamine functionalized active carbon material. The material is composed of the following components in parts by mass: 40-100 parts of active carbon (AC), 30-90 parts of o-methoxybenzoic acid (OMBA), 30-90 parts of diethylenetriamine (DETA), 100-130 parts of dicyclohexylcarbodiimide (DCC), 30-100 parts of absolute ethyl alcohol and 30-100 parts of dichloromethane.

Description

technical field [0001] The invention belongs to a novel material, which is an activated carbon material functionalized with o-methoxybenzoic acid diethylenetriamine, and belongs to the technical field of material chemical industry. Background technique [0002] Materials chemistry is a science that studies the design, preparation, composition, structure, characterization, properties and applications of materials from a chemical point of view. The nature of disciplines and border disciplines. With the rapid development of social economy and the continuous progress in the fields of materials science and chemical science, emerging industries such as new energy, new materials, and biotechnology have emerged one after another. It has important strategic significance and broad application prospects. [0003] Rare earth elements have been discovered since Finn Gadolin separated yttrium in 1794. Most rare earth elements have paramagnetic and optical properties. The birth of the f...
