Abstract

The invention discloses hydrophilic active carbon modified by sodium acetate and a preparation method thereof. The hydrophilic active carbon is formed by loading sodium acetate on the surface of the carbon framework of active carbon. The preparation method comprises the following steps of: sequentially carrying out high-temperature treatment on an active carbon raw material, soaking in a sodium hydroxide solution, drying, activating, soaking in ethyl acetate and carrying out esterolytic reaction, nitrogen purging desorption and vacuum desorption to obtain the hydrophilic active carbon. The preparation method disclosed by the invention has the advantages of easiness for operation and low cost; the prepared hydrophilic active carbon has the advantages of stability in structure, large specific area, less carbon loss, high adsorption capacity and large volume on water vapors, stability in adsorption property and good reusability.

Description

technical field

[0001] The invention discloses a sodium acetate-modified hydrophilic activated carbon and a preparation method thereof, in particular to the process of synthesizing a hydrophilic organic functional group on the surface of the activated carbon by using an organic reagent; it belongs to the field of catalytic modification. Background technique

[0002] Water vapor is one of the ubiquitous substances in nature. However, in some specific environments, such as precision instrument laboratories, warehouses, petroleum liquefied gas stations, etc., it is necessary to strictly control the content of water vapor to prevent major safety accidents caused by short circuits, corrosion, condensation, etc. with loss.

[0003] Adsorption is widely used because of its simple operation, easy recovery and avoidance of secondary pollution. Activated carbon has become one of the preferred adsorbents due to its developed pore structure, large specific surface area, abundant surfa...
