Abstract
The invention discloses a method for preparing a bamboo shoot shell adsorbing material, belonging to the field of preparation of adsorbing materials. The bamboo shoot shell adsorbing material with good adsorption performance is prepared by utilizing bamboo shoot shells as raw materials. The preparation method comprises the following steps: preparing bamboo shoot shell powder, performing epoxy activation treatment on the bamboo shoot shell adsorbing material, performing ligand coupling on the bamboo shoot shells subjected to epoxy activation, thereby obtaining the bamboo shoot shell adsorbing material. According to the preparation method, the process is simple, the requirement of equipment is low, the raw material source is wide, the price is low, and the prepared bamboo shoot shell adsorbing material is high in adsorption rate.
Description
Technical field
The invention belongs to sorbing material preparation field.
Background technology
Along with the development of China's economic, modern industry is produced and is produced a large amount of waste water containing heavy metal and directly enters people's water body, causes the pollution of a lot of river, reservoir, lake and surrounding sea areas, and directly has influence on the quality of underground water, also can work the mischief to health.The waste water of people's heavy metal and the environmental effect brought thereof are more and more paid close attention to, and the Treatment process that current heavy metal is polluted becomes study hotspot.The derivative of cellulose powder and shitosan has very strong selection attraction, for sewage disposal provide abundance, cost low, be easy to process and the characteristic such as easily biological-degradable, and there is significant advantages such as reducing secondary pollution.The pollutants such as cellulose adsorbent Adsorption of Heavy Metals and ionic dye are by hydroxyl being introduced several functions group, cause heavy metal adsorption to increase capacity.For this reason, prepare various effective sorbing material with vegetable material to receive much concern.
There is abundant bamboo resource in China, the annual Compositions of Bamboo Shoot Shell that all output is a large amount of, bamboo shoot case fibre has porosity characteristic, bamboo shoot shell itself has certain oil absorption, contains more tannin isoreactivity material, containing multiple ortho positions phenolic hydroxyl structure in tannin in bamboo shoot shell simultaneously, can as a kind of multidentate ligand and metal ion generation complex reaction, can be good at Adsorption of Heavy Metal Ions, at present Compositions of Bamboo Shoot Shell is studied and utilize few, the idle waste of most Compositions of Bamboo Shoot Shell.
Summary of the invention
The object of this invention is to provide and utilize Compositions of Bamboo Shoot Shell to prepare the method for Compositions of Bamboo Shoot Shell sorbing material as raw material.
The present invention is achieved by the following technical programs: a kind of Compositions of Bamboo Shoot Shell sorbing material preparation method, comprises the preparation of (1) Compositions of Bamboo Shoot Shell powder: mao bamboon Compositions of Bamboo Shoot Shell dried, and pulverize, sieve (40 ~ 60), make Compositions of Bamboo Shoot Shell powder; (2) the epoxy activation process of Compositions of Bamboo Shoot Shell sorbing material: be 0.7molL by Compositions of Bamboo Shoot Shell powder concentration
-1sodium hydroxide solution, add 1.0mLg
-1crosslinking agent B DDE, carry out activation process, activation temperature 25 DEG C, soak time 8h, after process, filter with sand core funnel, acetone washing by soaking, then spend deionized water, obtain epoxy activation Compositions of Bamboo Shoot Shell; (3) ligand cou of epoxy activation Compositions of Bamboo Shoot Shell: epoxy is activated Compositions of Bamboo Shoot Shell powder and carry out ligand cou process, in ligand cou, tannic acid solution concentration is 3%, and sodium borohydride solution consumption is 1.5mLg
-1, the lower 40 DEG C of oscillating reactions 12h of nitrogen protection, reaction terminates rear filtration, with 0.01mol/LHCl washing, then spends deionized water, obtains Compositions of Bamboo Shoot Shell sorbing material.
The present invention has following beneficial effect:
Preparation process is simple, low to the requirement of equipment, and raw material sources are wide, and price is low, and the Compositions of Bamboo Shoot Shell sorbing material adsorption rate of preparation is high.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.

-1sodium hydroxide solution, add 1.0mLg
-1crosslinking agent B DDE, carry out activation process, activation temperature 25 DEG C, soak time 8h, after process, filter with sand core funnel, acetone washing by soaking, then spend deionized water, obtain epoxy activation Compositions of Bamboo Shoot Shell; 3. the ligand cou of epoxy activation Compositions of Bamboo Shoot Shell: accurately take 2g epoxy activation Compositions of Bamboo Shoot Shell powder and put into 100mL triangular flask; carry out ligand cou process; in ligand cou, tannic acid solution concentration is 3%; sodium borohydride solution consumption is 3.0mL; the lower 40 DEG C of oscillating reactions 12h of nitrogen protection, reaction terminates rear filtration, washs with 0.01mol/LHCl; spend deionized water again, obtain Compositions of Bamboo Shoot Shell sorbing material.
Carry out Staticadsorption experiment, adsorbent amount 0.5g, simulated wastewater liquor capacity is 50ml, and copper sulphate initial concentration is 100mgL
-1, T=25 DEG C, as pH=5.0, Compositions of Bamboo Shoot Shell sorbing material is to Cu
2+adsorption rate reaches more than 90%.
Compositions of Bamboo Shoot Shell sorbing material preparation method process of the present invention is simple, low to the requirement of equipment, and raw material sources are wide, and price is low, and the Compositions of Bamboo Shoot Shell sorbing material adsorption rate of preparation is high.
Above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
