Technical field
The present invention relates to a kind of heavy metal absorbent.
Background technology
With the quickening of the development especially process of industrialization of society, one Tough questions of the thing followed are more and more
Heavy metal by the various approach such as trade effluent, atmospheric sedimentation enter natural water body in, natural water body is by different degrees of
Heavy metal pollution.Heavy metal easily enters human body because itself can not be by natural degradation by food chain, seriously endangers the mankind
Health, therefore the heavy metal pollution in water body increasingly causes the idea of people
Traditional heavy metal polluted waste water treatment technology includes the precipitation method, ion-exchange, electrochemical process and activated carbon and inhaled
Attached method etc..In recent years, all begin to focus on both at home and abroad using natural minerals or biomass and be used as the material of adsorption treatment heavy metal wastewater thereby
Material, this kind of sorbing material of developmental research at present is a lot, such as zeolite, clay, kaolin, flyash, mud coal, but it is imitated
Fruit is still unsatisfactory.Therefore, the sorbing material for seeking high efficiency low cost is always one of target of research of people.
China is pearl big producer, and a large amount of pearl oysters are dropped after adopting pearl, and utilization rate is low, pollutes environment.Master in clam shell
It is calcium carbonate to want composition, and wide material sources are cheap, is high-quality natural carbonic acid calcium source.The present invention is right in terms of water process
Shell powder carry out research invent it is a kind of can effective absorbing heavy metal ions in water adsorbent.
The content of the invention
The heavy metal absorbent that shell powder is raw material, the heavy metal adsorption are fired it is an object of the present invention to provide a kind of
Agent has the characteristics of adsorption capacity is strong, economic and environment-friendly, environment-friendly.Another object of the present invention is to provide an above-mentioned huge sum of money
Belong to the preparation method of adsorbent.
In order to realize first above-mentioned purpose, present invention employs following technical scheme：
A kind of to fire the heavy metal absorbent that shell powder is raw material, the heavy metal absorbent includes firing shell powder I and burnt
Shell powder II processed, the mass ratio for firing shell powder I and firing shell powder II is 1：10~10：1；Fire shell powder I be 100 DEG C~
The firing shell powder of 300 DEG C of sintering, fire the firing shell powder that shell powder II is 500 DEG C~700 DEG C sintering.
Preferably, the described mass ratio fired shell powder I and fire shell powder II is 1~10:1.
Preferably, the described particle diameter fired shell powder I and fire shell powder II is 1~30 micron.
Preferably, the described source fired shell powder I and fire shell powder II include hydriopsis cumingii, wrinkle hat freshwater mussel and
One or more mixing in anodonta woodiana pacifica.
In order to realize second above-mentioned purpose, present invention employs following technical scheme：
The preparation method of one group of heavy metal absorbent, this method comprise the following steps：
1) clam shell is collected, clear water removes the dirt of shell surface and remaining slough；
2) clam shell cleaned up is tentatively crushed to it, reuse ball mill it is crushed, milled processed,
It is 1~30 micron to be dried after air-flow and particle diameter is made, and is finally burnt respectively at 100 DEG C~300 DEG C and 500 DEG C~700 DEG C
System, obtain firing under two kinds of different temperatures and form shell powder, then by 1：10~10:1 ratio carries out mixing preparation, is fired
Shell powder is the adsorbent of raw material.
The present invention goes the adsorbent of the firing shell powder of heavy metal ion in water removal directly to sow by heavy metal pollution
In water body or clean in link to be directly added into clear water in daily fruits and vegetables and wash.As adsorbent remove water body in heavy metal from
Son.Heavy metal ion includes arsenic ion, mercury ion, lead ion etc. in described water.
The present invention has excellent pore structure and adsorbable metal ion after firing according to shell powder, is made into day
Right adsorbent.It is of the present invention to fire the adsorbent that shell powder is raw material, as the natural sorbing material of high-efficiency and economic, it is applied to
Remove all kinds of contaminated water bodys such as river, underground water, industrial wastewater and daily fruits and vegetables cleaning in metal ion.
Shell powder of the present invention of firing has the characteristics that for the adsorbent of raw material：
1) adsorption capacity is strong：In the experiment that 1/100 ratio is 1g adsorbents and 100g polluted water bodies.Removing to arsenic
Rate is up to 95%, and 99% is up to the clearance rate of mercury, and 95% is up to the clearance rate of lead.
2) it is economic and environment-friendly：Clam shell source is sufficient, cheap, is advantageous to largely produce.
3) it is environment-friendly：Any toxic organic solvents need not be added during preparation and use, as natural goods
Matter, ecological risk are small.
