Description
Technical field
The present invention relates to environmental technology field, the modified heavy metal ion suction of more particularly, to a kind of amination graphene oxide
Enclosure material.
Background technology
Heavy metal generally refers to more than 60 kind element or density 45 kinds of elements more than 5 more than 4 for the density, but due to
Toxicity in water and soil for the different heavy metals differs greatly, thus environmental science people be generally concerned with vanadium, chromium, cobalt,
The metal ions such as silver, copper, zinc, cadmium, stannum, hydrargyrum, lead.Heavy metal is prevalent in nature with simple substance or compound form mostly
In, too big threat will not be constituted to ecological and the mankind.But in the last few years, because the mankind are to the exhaustive exploitation of metalliferous mineral and smelting
Refining, produce in the industrial processes such as chemical industry, electronics, instrument, machine-building again contain in a large number heavy metal ion (cadmium, chromium, copper, hydrargyrum,
Nickel etc.) waste water, these are all the primary pollution source of water and Soil Environmental Pollution.Heavy metal ion can assemble in human body thus
Lead to the damage of poisoning, cancer and nervous system.
Heavy metal both can be directly entered water body, soil and air, cause environmental pollution it is also possible to water body, soil and
Shift between air, cause the indirect pollution of all kinds of environmental key-elements.Because heavy metal will not nature or biodegradation, therefore a huge sum of money
The place to go belonging to pollution is more difficult.
At present, the minimizing technology of common heavy metal ion mainly has: flocculence, the sedimentation method, membrane separation process, biological treatment
Method, ion exchange and absorption method etc..Absorption method will not produce secondary pollution in terms of administering heavy metal ions in wastewater, reaction
Efficiency high, effect is significant and equipment are simple, and therefore it is most widely used.The core of absorption method is the selection of adsorbent how
Improve the adsorption effect of adsorbent, be the technical barrier that those skilled in the art face.
Content of the invention
