Description
Technical field
The present invention relates to material for water treatment technical field, specifically sorbing material of a heavy metal species and preparation method thereof and
Using.
Background technology
Arsenic is one of very strong element of toxicity, is also the inorganic toxins of main removal in various countries' drinking water standard.In nature
It is many in water body to exist with trivalent and pentavalent state.But it is used as a kind of metallic element, deposited with the state of common cation
, and mainly exist with arsenous anion and arsenate form.Even if the technology in modern times such as reverse osmosis membrane (RO) is gone to trivalent arsenic
Except rate is only 50% or so, it is impossible to meet the filtration needs to arsenic.In addition, filtering material is to arsenic and the great heavy metal mistake of toxicity
Filter, it is necessary to take into account the fixation problem after absorption.Conventional porous ceramics and ceramic element can using diatomaceous natural porous structure
To remove bacterium and larger molecular organicses, but the arsenic and heavy metal of ionic condition can not be removed.It is many using illiteracy in existing technology
The raw materials such as de- stone, medical stone, its heavy metal ion and cause evil toxin have very strong absorption affinity, and wollastonite has very big in China
Reserves, but it does not expand in being long placed in water, Adsorption of Heavy Metals effect is poor, thus use wollastonite be raw material be used for process a huge sum of money
The relevant information of category etc. is less.

Another object of the present invention is to provide a kind of preparation method of the sorbing material of heavy metal, comprises the steps of：
1) water of 9.8 times of tetrahydrofurfuryl alcohol and its quality is mixed, tetrahydrofurfuryl alcohol solution is obtained；By calcium acetate and its quality
3.8 times of deionized water mixing, is obtained calcium acetate solution；
2) by wollastonite and polyvinyl resin mixed grinding, 100 mesh sieves are crossed, is subsequently adding tetrahydrofurfuryl alcohol solution, and 83
Heated sealed stir process 65-70min at DEG C, is then cooled to 70 DEG C and calcium acetate solution is added dropwise while stirring, then be warming up to again
128 DEG C of ultrasonically treated 30min, then stir to dry at a temperature of 100 DEG C, then calcine 3.8h at a temperature of 330 DEG C, obtain final product
Filtering material.
Another object of the present invention is to provide application of the filtering material in water process.
Compared with prior art, the beneficial effects of the invention are as follows：
Filtering material of the invention has absorption fixing function high to trivalent arsenic and pentavalent arsenic, and the present invention is when waterpower is contacted
Between in the case of 10 seconds, arsenic removal lead chromium mercury manganese ion clearance up to more than 90% can be removed；Filtered through filtering material of the invention
Water afterwards has the alkalescent of stabilization.Filtering material of the invention has strong reducing property to hexavalent chromium, to poisonous sexavalence
Chromium, can be reduced to nontoxic and beneficial trivalent chromium；Filtering material of the invention to the chlorine residue gas and chemical disinfection byproducts in water,
There is removal effect.Filtering material of the invention mainly apply water and waste water filtering, after use, can with acid treatment after, again
Calcining, realizes that material repetitive cycling is used；The preparation method reaction condition that the present invention is provided is gentle, simple to operate, low cost.
