Embodiment 1

[0018] Embodiment 1 (contrasted with corresponding embodiment 1 and the proportioning value by weight in the table above), is prepared according to the following steps:

[0019] (1) raw materials including bamboo chips, bamboo slices, scraps, bamboo silk are pulverized into 60-80 order bamboo powder;

[0020] (2) Preparation of hydrothermal bamboo charcoal: 20 parts by weight of 60-80 mesh bamboo powder and 7 parts by weight of anhydrous ferric chloride are placed in 100 parts by weight of water, stirred and mixed at room temperature In a lined stainless steel reaction kettle, react at 180°C for 12 hours, cool naturally, filter with suction, wash until neutral, and then dry to obtain hydrothermal bamboo charcoal;

[0021] (3) Preparation of activated hydrothermal bamboo charcoal: mix the hydrothermal bamboo charcoal obtained in step (2) with 2 parts by weight of sodium hydroxide and 100 parts by weight of water, stir at room temperature for 1 hour, suction filter, wash until n...

Abstract

The invention discloses a method for producing a biomass charcoal dye adsorbent. The method comprises the following steps: pulverizing bamboo processing residues into 60-80-mesh bamboo powder, and conducting hydrothermal reaction on bamboo powder under the Lewis acid environment to prepare hydrothermal bamboo charcoal; activating the obtained hydrothermal bamboo charcoal with inorganic base so as to obtain an activated hydrothermal bamboo charcoal adsorbing material. The method is simple in process, low in raw material cost and large in adsorbing capacity. The prepared adsorbing material can be applied to adsorption treatment of cationic dye, and has an excellent treating effect. Not only is recycle of bamboo processing residue resource realized, but also the cheap and efficient novel adsorbent is obtained, and the development of environmental protection causes is promoted.

Description

technical field [0001] The invention belongs to the field of preparation of biomass carbon adsorption materials and environmental pollution control, in particular to a production method for preparing biomass adsorption materials through hydrothermal carbonization with bamboo powder as the main material, specifically Lewis acid catalyzed hydrothermal bamboo-based biomass carbon Methods of production of adsorbent materials. Background technique [0002] Statistics from the Eighth National Forest Resources Inventory show that my country's bamboo forest area is 6.01 million hectares, and the bamboo forest area, bamboo stock, bamboo product output and export volume all rank first in the world, and bamboo processing technology and bamboo product innovation capabilities are at the world's advanced level. But at present, the raw bamboo utilization rate of various bamboo board profiles in my country is only 20% to 50%, and a large amount of bamboo processing residues such as bamboo c...
