Example Embodiment

[0012] A kind of jute rod modified activated carbon, made from the following parts by weight (kg) of raw materials: jute rod 140, zeolite 5, silica gel 8, activated carbon fiber 13, palygorskite 8, bentonite 8, polyacrylic acid 7, humic acid 9, Rectorite 4. Modified diatomite 4. Appropriate amount of water;

[0013] The modified diatomaceous earth is made of the following parts by weight (kg) of raw materials: diatomaceous earth 106, medical stone 33, nano carbon 1.4, ascorbic acid 1.5, coix seed oil 1.6, sodium dodecyl benzene sulfonate 1.5, Zinc gluconate 2.5, dandelion powder 2.4; the preparation method is to put diatomaceous earth and medical stone into a calciner at 550°C for 3.4 hours, take it out, soak it in 15% hydrochloric acid solution for 4 hours, and filter it out. Repeatedly washing with clean water, drying, adding to water, at the same time, adding nano carbon, ascorbic acid, zinc gluconate, grinding to obtain slurry, spray drying, mixing other remaining ingredi...

Abstract

A jute stalk modified active carbon is prepared by the following raw materials by weight: 130-150 parts of jute stalk, 4-6 parts of zeolite, 7-9 parts of silica gel, 10-15 parts of active carbon fiber, 7-9 parts of palygorskite, 7-9 parts of bentonite, 6-8 parts of polyacrylic acid, 8-10 parts of humic acid, 4-5 parts of rectorite, 4-5 parts of modified diatomite, and a proper amount of water. The jute stalk is used as a raw material to make the produced active carbon have advantages of developed aperture structure, big specific surface area, high adsorption speed, and good adsorption capability for various solutes and free gasses; silica gel is used to make the active carbon have advantages of large adhesion stress and difficult disintegration; active carbon fiber is matched to use to make the active carbon have strong absorption function; and an adsorption value and a methylene blue absorption valve of the active carbon greatly exceed standard values of the national wood water purification first-level active carbon, and the invention develops new raw materials for manufacturing the active carbon.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a jute stalk modified activated carbon and a preparation method thereof. Background technique [0002] Activated carbon is widely used to adsorb harmful substances. The raw materials of activated carbon are mainly carbon-containing substances, including wood, animal bones, blood, coal, petroleum and other minerals, which are obtained by high-temperature carbonization and activation. [0003] Jute, Tiliaceae Jute, bast fiber crop, annual herb. Also known as network hemp, green hemp. There are about 40 species in the genus Jute, and the two species with cultivation value are round-fruited jute and long-fruited jute. Jute fiber has the characteristics of good hygroscopicity and fast loss of water, and is mainly used for textile sacks and burlap. [0004] The jute stalks after the jute skin is removed are all burned at present, causing environmental pollution and poten...
