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
The invention belongs to the preparation of biomass carbon sorbing material and field of environment pollution control, the production method preparing biomass absorbent material is carbonized, the specifically production method of Louis acid catalysis hydro-thermal bamboo based biomass charcoal sorbing material with bamboo powder for main material carries out hydro-thermal in particular to a kind of.
Background technology
The display of the 8th forest assessment in whole nation statistics, China's bamboo grove area has 6,010,000 hectares, and the accumulation of bamboo grove area, bamboo wood, bamboo product output and export volume all rank first in the world, and bamboo process technology and bamboo product innovation capability are in advanced international standard.But the former bamboo utilization rate of current China various bamboo clappers section bar is only 20% ~ 50%, have a large amount of bamboo surplus material of processing as bamboo bits, sawdust, leftover pieces etc., make fuel every year and use, economic benefit is lower.Therefore, how improving the utilization rate of bamboo resource and the economic benefit of industrial wood waste, is enterprise and the researcher's facing challenges of being engaged in bamboo processing.
Summary of the invention
The production method of the biomass carbon dye sorbent that the object of the present invention is to provide a kind of absorption property good.
Solving the problems of the technologies described above adopted technical scheme is:
A production method for biomass carbon dye sorbent, follows these steps to carry out:
(1) by comprise bamboo bits, bamboo chip, leftover pieces, bamboo silk raw meal be broken into 60-80 order bamboo powder;
(2) hydro-thermal bamboo charcoal preparation: the water 60-80 order bamboo powder of 20 weight portions and 4-10 weight portion lewis acid being placed in 80-120 weight portion, at room temperature be uniformly mixed and be placed in band teflon-lined stainless steel cauldron, then react under 170-240 DEG C of condition 8-24 hour, cooling naturally, suction filtration, washing to neutral post-drying, namely obtain hydro-thermal bamboo charcoal;
(3) activate the preparation of hydro-thermal bamboo charcoal: mixed with 1-4 parts by weight of inorganic alkali and 80-120 weight parts water by the hydro-thermal bamboo charcoal that step (2) obtains, after stirring at room temperature 0.5-3h, suction filtration, washing are to neutral post-drying.
The production method of described biomass carbon dye sorbent, in step (2), said lewis acid is any one or above-mentioned lewis acidic mixture in anhydrous ferric chloride, anhydrous zinc chloride, anhydrous Aluminum chloride lewis acid.
The production method of described biomass carbon dye sorbent, the inorganic base described in step (3) is the mixture of NaOH, any one or two kinds of inorganic bases of potassium hydroxide.
The catalyst that the present invention adopts lewis acid to carbonize as hydro-thermal, make bamboo powder degree of carbonization become large, carbonizing production density diminishes.The adsorption capacity of bamboo based biomass charcoal to dye of positive ion methylene blue that the bamboo based biomass charcoal sorbing material produced is prepared than corresponding catalyst-free significantly improves, more than 603mg/g can be reached to the adsorption capacity of dye of positive ion methylene blue, to the 500mg/L methylene blue of high concentration, when solid-to-liquid ratio is 1g/L, percent of decolourization (clearance) can reach more than 98.8%, and the saturated adsorption capacity of bamboo based biomass charcoal to methylene blue prepared by the catalyst-free of correspondence is only 262mg/g.Using the hydro-thermal bamboo Charcoal Adsorption material becoming adsorption rate high as the residue of bamboo processing, environmental contaminants modification, to the dye of positive ion, there is good absorption property, be conducive to the fields such as the process being applied to industrial wastewater, and turn waste into wealth, drastically increase the added value of bamboo powder.
Accompanying drawing explanation
Fig. 1 is the isothermal adsorption line chart of sample to methylene blue of the embodiment of the present invention 1 gained.
Fig. 2 is the percent of decolourization figure of sample to methylene blue of the embodiment of the present invention 1 gained.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
Table 1 embodiment 1-8 pulp furnish (weight portion)
Embodiment 1 (during contrast is shown corresponding embodiment 1 and weight value), is prepared as follows:
