Description
Technical field
The present invention relates to a kind of adsorbent, particularly to one using plant plait fiber as raw material, the one of modified preparation
Adsorbent and method, belong to adsorbing material field.
Background technology
Along with developing rapidly of process of industrialization, many waste water of industrial discharge such as plating, ore dressing and process hides, waste gas and useless
Slag often results in the heavy metal pollution of water environment, heavy metal can not biodegradation, and live body in be enriched with, cause various disease
Disorderly with body, very harmful to organism.
The technique that efficiently separates being presently used for removing heavy metal ions in sewage has: at the exchange of precipitation, ion, electrochemistry
Reason, membrane technology, evaporation coagulation, reverse osmosis and electrodialysis etc., but the application of these technology is limited, closely by technique and economy sometimes
Over Nian, organism absorption by living is removed the method for heavy metal and has been caused concern, this method mainly utilize hyperaccumulative plant,
Algae and microorganism heavy metal have bigger absorbability to remove the heavy metal in waste water, but process dirt with the organism lived
Water is limited by Biomass and the growth characteristics of organism itself, and such method is also unsuitable for applying on a large scale the most so far.
Modified cellulose class adsorbent is one of important development direction of current cellulose functional high molecule material.Such adsorbent does not draws
Entering new pollutant, consume energy low, so there being important application in water processes, and being more easy to regeneration than adsorbent resin again, and
Stability is high, and adsorptive selectivity is special, and adsorbent price is far below adsorbent resin.
Japanese pagodatree leaf duckweed is a kind of water plant swum on the water surface, for aquatic weed, with Japanese pagodatree leaf duckweed for cellulose origin system
Standby adsorbent is a kind of Land use systems of abandoned biomass resource, and can realize utilizing a kind of abandoned biomass resource to administer ring
The problem of environment pollution.The present invention is using Japanese pagodatree leaf duckweed as raw material, in the effect of isopropanol, NaOH solution and citric acid solution
Under, modification is prepared as a kind of grass fiber adsorbent.
Summary of the invention
The present invention provides a kind of fiber adsorbing substance and preparation method thereof.The method is realized by techniques below route:
(1) Japanese pagodatree leaf duckweed clean water is removed earth, clean with distilled water flushing the most again, and put in baking oven and dry
To constant weight；
(2) drying object pulverizer is pulverized, and certain purpose sieve；
(3) collect sieve powder, then the isopropanol reaction by powder Yu certain solubility, and be stirred continuously；
(4) being filtered by solution, and be carried out with distilled water, wash products is placed in drying baker and dries；
(5) dry product to be reentered in container, add the NaOH solution of certain solubility, and be stirred continuously and make it fully react；
(6) being filtered by solution, and be carried out with distilled water, wash products is placed in drying baker and dries；
(7) dry product to be reentered in container, add the citric acid solution of certain solubility, and be stirred continuously and make it the most anti-
Should；It is neutral that the most last distilled water is washed till solution, and filters, after drying product.
Preferentially, step (1) in, dry temperature be 50-70 DEG C.
Preferentially, step (2) in, the mesh number of sieve is 100-200 mesh.
Preferentially, step (3) in, the solubility of isopropanol is 15-20%, and the response time is 12-15 hour.
Preferentially, step (4), (6), (8) in, dry temperature conditions be at 50-60 DEG C, drying time is 10-20 hour.
Preferentially, step (5) in, the solubility of NaOH is 0.1-0.5mol/L, and the response time is 1-2 hour.
Preferentially, step (7) in, the solubility of citric acid is 0.5-1mol/L, and the response time is 2-4 hour.
The present invention has following advantages and a characteristic:
(1) abundant raw material source, with low cost；
The most environmentally friendly, not secondary pollution.
