Embodiment 1

[0039] A preparation method of mussel shell powder / carboxymethyl cellulose composite gel adsorbent, said method comprising the following steps:

[0040] 1) Calcining mussel shells at 500°C for 4 hours at 500°C for 4 hours to form mussel shell powder;

[0041] 2) Mix carboxymethyl cellulose and water at a dosage ratio of 5g: 50mL and stir until carboxymethyl cellulose is completely dissolved to obtain a thick liquid, and the obtained mussel shell powder and thick liquid are mixed at a dosage ratio of 10g : 50mL ratio is mixed and stirred so that the mussel shell powder is evenly dispersed to obtain a dispersion;

[0042] 3) Add 60g of cross-linking agent to every liter of dispersion to make it form a gel, freeze-dry to obtain the mussel shell powder / carboxymethyl cellulose composite gel adsorbent, the obtained mussel shell powder / carboxymethyl cellulose composite The gel adsorbent is in the form of a hard sheet.

Embodiment 2

[0044] A preparation method of mussel shell powder / carboxymethyl cellulose composite gel adsorbent, said method comprising the following steps:

[0045] 1) Calcining mussel shells at 600°C for 3 hours at 600°C for 3 hours to form mussel shell powder;

[0046] 2) Mix carboxymethyl cellulose and water at a dosage ratio of 20g: 50mL and stir until the carboxymethyl cellulose is completely dissolved to obtain a thick liquid. The obtained mussel shell powder and thick liquid are mixed at a dosage ratio of 30g : 50mL ratio is mixed and stirred so that the mussel shell powder is evenly dispersed to obtain a dispersion;

[0047] 3) Add 100g of cross-linking agent to every liter of dispersion to make it form a gel, freeze-dry to obtain the mussel shell powder / carboxymethyl cellulose composite gel adsorbent, the obtained mussel shell powder / carboxymethyl cellulose composite The gel adsorbent is in the form of a hard sheet.

Embodiment 3

[0049] A preparation method of mussel shell powder / carboxymethyl cellulose composite gel adsorbent, said method comprising the following steps:

[0050]1) Calcining mussel shells at 500°C for 4 hours at 500°C for 4 hours to form mussel shell powder;

[0051] 2) Mix carboxymethyl cellulose and water at a dosage ratio of 5g: 50mL and stir until carboxymethyl cellulose is completely dissolved to obtain a thick liquid, and the obtained mussel shell powder and thick liquid are mixed at a dosage ratio of 10g : 50mL ratio is mixed and stirred so that the mussel shell powder is evenly dispersed to obtain a dispersion;

[0052] 3) Add 60g of cross-linking agent to every liter of dispersion to make it form a gel, dry at 90°C under 0.2atm to obtain the mussel shell powder / carboxymethylcellulose composite gel adsorbent, the obtained mussel shell powder / Carboxymethylcellulose composite gel adsorbent is fluffy and elastic block.

Abstract

The invention relates to the field of preparation of adsorption materials, in particular to a preparation method of mussel shell powder / carboxymethyl cellulose composite gel adsorbent. It includes: calcining mussel shells as raw materials until mussel shell powder is formed; dissolving carboxymethyl cellulose in water to prepare a thick liquid, and adding the obtained mussel shell powder into the thick liquid to disperse evenly , to obtain a dispersion; adding a crosslinking agent to the dispersion to form a gel, and drying to obtain a mussel shell powder / carboxymethyl cellulose composite gel adsorbent. The present invention can simply and efficiently prepare the fluffy mussel shell powder / carboxymethyl cellulose composite gel adsorbent with good adsorption properties; effectively utilize the mussel shells which are wastes from seafood processing, reduce the preparation components, and simultaneously Waste utilization is realized; the prepared mussel shell powder / carboxymethyl cellulose composite gel adsorbent can be reused.

Description

technical field [0001] The invention relates to the field of preparation of adsorption materials, in particular to a preparation method of mussel shell powder / carboxymethyl cellulose composite gel adsorbent. Background technique [0002] At present, the smog problem has attracted the attention of most countries. Due to the rapid development of industry and the destruction of furniture to the environment, my country's air pollution CO 2 The impact is very serious, SO 2 and many other industrial pollutants. The world is experiencing various disasters caused by global warming, CO 2 Filtration and emission reduction has become an important topic in the scientific community in the near future, especially for CO 2 Absorption technology development. CO in the flue gas of coal-fired power plants 2 accounted for global CO 2 more than 60% of the total emissions, apparently, the CO in the flue gas 2 Absorption is the realization of CO 2 The most effective way to reduce emission...
