The present invention, which discloses one kind, can adsorb ceramic material of heavy metal and preparation method thereof.The ceramic material is prepared by following substance: 43 ~ 45 parts of attapulgite, 20 ~ 25 parts of glass powder, 20 ~ 25 parts of quartz, 15 ~ 20 parts of clay, 15 ~ 20 parts of pore creating material, 3 ~ 5 parts of bentonite, 2 ~ 4 parts of black talc, 2 ~ 5 parts and 1 ~ 3 part of nano-titanium of Suzhou soil.This method are as follows: after mixing attapulgite, glass powder, quartz, clay, pore creating material, bentonite, black talc and Suzhou soil, mill causes 300 ~ 400 mesh, spare；Drying, is then added nano-titanium, is then granulated；It is calcined at 550 ~ 650 DEG C, obtains the ceramic material that can adsorb heavy metal.Product of the present invention has the performance of efficient absorption heavy metal ion, and the existing adsorbent on the market that compares, preparation cost substantially reduce.
Description
Technical field
The invention belongs to functionality ceramic fields, and in particular to one kind can adsorb ceramic material and its preparation of heavy metal
Method.
Background technique
Heavy metal original meaning refers to that (density is greater than 4.5 grams of gold per cubic centimeter to metal of the specific gravity greater than 5 in general
Belong to), including gold, silver, copper, iron, lead etc., heavy metal is accumulated in human body to be reached a certain level, and will cause slow poisoning.Heavy metal
Ion is usually present in water body in the form of free state, and if the concentration of heavy metal ion is exceeded by direct shadow in drinking water
Ring the health of drinking person.
The adsorbent with heavy metal ion adsorbed function being prepared using ceramic material, absorption property are usually compared
Other materials adsorbent is poor, but ceramic material is as adsorbent, and since raw material is easy to get and inexpensively, the prospect of application is huge.
Summary of the invention
The present invention overcomes drawbacks described above, and ceramic material of heavy metal and preparation method thereof can be adsorbed by providing one kind, the pottery
Ceramic material has the characteristics that efficient absorption heavy metal ion.
Technical solution of the present invention is as follows.
A kind of ceramic material that can adsorb heavy metal, is prepared by following substance: 43 ~ 45 parts of attapulgite, glass
20 ~ 25 parts of powder, 20 ~ 25 parts of quartz, 15 ~ 20 parts and 15 ~ 20 parts of pore creating material of clay.
A kind of ceramic material that can adsorb heavy metal, is prepared by following substance: 43 ~ 45 parts of attapulgite, glass

Further, the pore creating material is starch.
Further, the starch is cornstarch or sweet potato starch.
Further, the starch is 100 ~ 200 mesh.
A kind of preparation method for the ceramic material that can adsorb heavy metal, includes the following steps:
(1) after mixing attapulgite, glass powder, quartz, clay, pore creating material, bentonite, black talc and Suzhou soil, grinding is caused
300 ~ 400 mesh, it is spare；
(2) step (1) obtained material is dried, nano-titanium is then added, is then granulated；
(3) it is calcined at 550 ~ 650 DEG C, obtains the ceramic material that can adsorb heavy metal.
In the above method, in step (3), the specific steps of the calcining are as follows: the heating rate of 2 ~ 3 DEG C/min, which heats up, to be caused
550 ~ 650 DEG C, heat preservation stops 50 ~ 70min, and then with the rate of temperature fall of 1 ~ 2 DEG C/min, cooling causes room temperature.
Compared with prior art, present invention has an advantage that
Product of the present invention has the performance of efficient absorption heavy metal ion, and the existing adsorbent on the market that compares, preparation
Cost substantially reduces.
