Abstract
The invention discloses a kind of efficient convenient remarkable processing method improving attapulgite, diatomite microstructure and absorption property.The high temperature pyrolysis utilizing Physics Irradiation to produce, sputtering and COULOMB EXPLOSION effect, separate loose by attapulgite inner nanorods crystal structure efficient solution, and then increase attapulgite specific area, can significantly improve the absorption property of attapulgite.Meanwhile, impurity in diatomite duct can be removed, increase its porosity, thus promote its absorption property.Modified clay can adhere to auxiliary agent as agricultural chemicals and high-efficiency adsorbent uses.
Description
Technical field
The present invention relates to a kind of nano-material modified field, be specifically related to a kind of efficient convenient remarkable new method improving natural clay attapulgite, diatomite microstructure and adsorptivity.
Background technology
Concave-convex clay rod refers to attapulgite to be a kind of clay mineral of key component, it is a kind of hydrous magnesium aluminosilicate with fibrous crystalline structure, as a kind of natural nano structure mineral material with nanochannel structure, Concave-convex clay rod is owing to having larger specific area and certain ion exchangeable, can be used as adsorbent, some organic dyestuff of Adsorption are widely used.Natural attapulgite rod crystal fiber easily flocks together and forms many crystalline substance bundles, and in rick structure, dispersiveness is lower, and its adsorption capacity is also subject to a definite limitation.Therefore, in order to effectively improve attapulgite absorption property, needing to carry out modification to it, improving its dispersive property.
Diatomite is generally formed by the dead later silicate remains of the unicellular alga being referred to as diatom, and its main component is SiO
2(usually more than 70%), and containing a small amount of Fe

3and organic impurities, usually in light yellow or light grey.Due to the micro-nano pore passage structure of diatomite uniqueness, there is larger porosity and specific area, be commonly used for insulation material, filtering material, filler, grinding-material, waterglass raw material, decolorizer and super-cell, catalyst carrier etc.But the existence of impurity makes some perforations block, cause its porosity and specific area to decline, have impact on its absorption property.Therefore, in order to play diatomaceous premium properties better, being necessary to remove its impurity, dredging its duct, improving its porosity.
At present, domestic for attapulgite and diatomaceous method of modifying research mainly concentrate on mechanical disruption, hydrothermal treatment consists, high-temperature process, pickling, organically-modified in the middle of.Although these methods improve the dispersiveness of attapulgite to a certain extent or improve diatomaceous porosity, but they often exist that energy consumption is higher, complex steps or introduce the shortcomings such as secondary pollution.For this reason, we have developed more efficient, convenient, environmental friendliness, method of modifying with low cost, are namely processed attapulgite (or diatomite) by Physics Irradiation, to significantly improve its dispersion and absorption property.Simultaneously, attapulgite after radiation modification and diatomite add in traditional agricultural chemicals by we, to improve the adhesion property of agricultural chemicals at blade face and soil surface, realize controlling the migration of pesticide molecule in surrounding medium, thus reduce agricultural chemicals to the pollution risk of environment.In addition, because modified adsorption by clay performance significantly improves, efficient waste water (heavy metal, organic pollution etc.) inorganic agent can be used as.
Summary of the invention
The invention provides a kind of efficient convenient remarkable processing method improving attapulgite, diatomite microstructure and absorption property, its principle is: the brilliant aggregation of attapulgite rod can effectively be dissociated by the sputtering produced by high-energy electron beam irradiation, high temperature pyrolysis and COULOMB EXPLOSION effect, thus improves the dispersiveness of attapulgite; Impurity in diatomite duct can be removed simultaneously, improve its aperture and pore volume distribution, thus improve diatomaceous porosity.More pesticide molecule can effectively be wrapped in attapulgite micro-nano network and diatomite hole by modified attapulgite and diatomite, the excellent rheological property of recycling clay is by the coarse structure blocks of plant leaf surface, thus the adhesion property of agricultural chemicals can be strengthened, improve ability to resist splash erosion, reduce agricultural chemicals and run off.In addition, attapulgite modified and diatomite can replace conventional clay, as High-efficient Water adsorbent, and process heavy metal and organic polluting water.
The technical solution used in the present invention is:
The efficient convenient remarkable processing method improving attapulgite, diatomite microstructure and absorption property, its concrete steps are as follows:
(1) 5-30kg attapulgite or diatomaceous snakeskin bag will be housed, be respectively 20-100 second through the high-energy electron beam irradiation of 5-15MeV energy and 10-100keV dosage successively as required;
(2) add in agricultural chemicals by the clay after irradiation according to 10-20% mass ratio, make the agricultural chemicals of controlled loss, formulation contains wettable powder, emulsion, granule etc.;
(3) using the clay after irradiation as adsorbent, for the treatment of the waste water containing heavy metal ion or organic pollution, addition controls within the scope of 0.1-5g/L according to pollutant levels.
Described snakeskin bag or the integral thickness of carton control at 20-30cm.
Beneficial effect of the present invention is:
1. effectively improve attapulgite dispersive property, reduce diatomite impurity content, improve diatomite porosity;
2, strengthen the adhesion property of agricultural chemicals at blade face or soil surface, reduce it and run off;
3, the absorption property of clay heavy metal ion or organic pollution is improved;
4, easy and simple to handle, can scale process, (100-500 yuan/ton) with low cost;
5, environmental friendliness, does not produce three industrial wastes (waste water, waste gas and waste residue).
