Description
Technical Field
The invention relates to the technical field of environmental wastewater treatment materials, in particular to a clay matrix type adsorbent and a preparation method thereof.
Background
In recent years, China focuses on the field of environmental protection, and is dedicated to restoring ecology and treating pollution. Water resources are the most basic elements for people to live and produce in society, so the problem of treating water pollution is mainly solved.
with the increasing industrial production and social production activities of human beings, many pollutants containing heavy metal ions are discharged into natural water bodies. Heavy metal ions in the water body can not be degraded by microorganisms, can exist for a long time and can enter a human body through a food chain to cause physiological dysfunction so as to cause various diseases. Therefore, the method has important significance in removing the heavy metal ions in the water body. So far, the main treatment methods for heavy metal pollution of water bodies include adsorption methods, chemical precipitation methods, ion exchange methods, membrane separation methods, biological flocculation methods and the like. Among them, the adsorption method has advantages of cheap and easily available materials, simple operation, and good heavy metal treatment effect, and is therefore regarded by researchers. In the adsorption method, heavy metal ions are usually removed by using a heavy metal ion adsorbent, which is diverse in types, including natural minerals (such as inorganic materials like zeolite and kaolinite), natural polymers (such as tannins, lignins and chitosan), and artificially synthesized or modified polymers (such as polystyrene-based resin and silica gel-based resin).
The adsorbent used in the domestic and foreign wastewater treatment is mainly an organic adsorbent, and the organic adsorbent has poor adsorption efficiency and thermal stability, low pollution resistance and short service life; and often require cooperation with other methods to achieve optimal separation. In order to overcome the disadvantages of organic adsorbents, the use of inorganic adsorbents is gradually attracting attention. Compared with organic adsorbents, the inorganic adsorbent has the advantages of high adsorption efficiency, good chemical stability, acid and alkali resistance, organic solvent resistance, long service life and the like, so the inorganic adsorbent has good application prospect in adsorbent separation.
In 1979, french scientist Davidovits proposed the concept of geopolymers (geopolymers) capable of being used as adsorbents, wherein geopolymers mainly refer to three-dimensional network gels formed by interaction of silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons and prepared from natural minerals, solid wastes or organic silicon-aluminum compounds and inorganic silicon-aluminum compounds serving as raw materials. The geopolymer used as the adsorbent has the advantages of an inorganic adsorbent, has no pollution in the preparation process and low energy consumption, can consume a large amount of industrial solid wastes, and is a green synthetic and green pollution-control adsorbing material.
