Abstract
The invention discloses a kind of Matteuccia strthiopteris modified adsorbent and preparation method thereof.Using Matteuccia strthiopteris as raw material, processing reaction process by isopropanol, potassium hydroxide solution and citric acid solution, modification is prepared as a kind of biomass adsorbent.The method abundant raw material source, with low cost and environmentally friendly, there is preferable application prospect.
Description
Technical field
The present invention relates to a kind of adsorbent, particularly to one using Matteuccia strthiopteris plant as raw material, the one of modified preparation
Adsorbent and technique, belong to sorbent material field.
Background technology
Along with the development of process of industrialization, heavy metal pollution is increasingly severe, owing to heavy metal can not be by microorganism
Degraded, can only occur the mutual conversion between various form in the environment, so, the elimination of heavy metal pollution is the most tired
Difficulty, can be enriched with in the body that heavy metal is lived, and causes various disease and body disorderly, 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.
Matteuccia strthiopteris widely distributed China various places, it contains a large amount of cellulose, can prepare cellulose modified adsorbent.This
Bright using Matteuccia strthiopteris as raw material, under the effect of isopropanol, potassium hydroxide solution and citric acid solution, modification is prepared as a kind of raw
Substance adsorber.
Summary of the invention
The present invention is to provide a kind of Matteuccia strthiopteris modified adsorbent and preparation method thereof.This preparation method passes through techniques below road
Line realizes:
By Matteuccia strthiopteris with clean water clean after, put into and baking oven carried out dry to constant weight；
(2) dried object pulverizer is pulverized, sieve；
(3) collect powder, by the isopropanol hybrid reaction of powder Yu certain solubility, and be stirred continuously；
(4) after reacting, solution filters, and is carried out with distilled water, and wash products is placed in drying baker and dries；
(5) the potassium hydroxide solution drying product and certain solubility reacts, and is stirred continuously and makes it react abundant；
(6) after reacting, solution filters, and is carried out with distilled water, and wash products is placed in drying baker and dries；
(7) the citric acid solution drying product and certain solubility reacts, and is stirred continuously and makes it fully react；
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 potassium hydroxide 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；
(2) technique is simple, easily operates；
The most environmentally friendly, not secondary pollution.
