Description

A kind of carbonic acid gas lanthanum-halloysite composite material and its preparation method and application
Technical field
The invention belongs to technical field of environmental pollution treatment, it is more particularly related to a kind of for adsorbing phosphate radical Carbonic acid gas lanthanum-halloysite composite material of ion and its preparation method and application.
Background technology
Lanthanum is the common adsorbent for repairing eutrophication water, principle be mainly in water phosphate radical life is combined with lanthanum At the lanthanum orthophosphate for being insoluble in water, by phosphate radical from water body fast eliminating.It is most at present to contain lanthanum since lanthanum nano particle is easily reunited Sorbing material is that lanthanum is carried in carrier, to reduce lanthanum nanoparticle agglomerates, strengthens its contact and absorption to phosphate radical. Diameter of carrier is small, and porosity is big, is conducive to lanthanum-containing materials with nanoscale in its area load, therefore carrier material characteristic (including Grain size, pore structure and its physicochemical properties etc.) load of lanthanum nano particle can be influenced, and then sorbing material containing lanthanum is influenced to dirt Contaminate the absorption of object.The research that phosphate radical is adsorbed about lanthanum support materials at present makes important progress.
Such as Chinese patent (application number CN201510721249.6) is using biomass anion exchange resin as carrier, at it Upper load nano lanthanum oxide forms biomass-based nano lanthanum oxide dephosphorization compound adsorbent；In addition, there is document report with zeolite, life Object carbon, expanded graphite, Coaseries kaolin are carrier, and lanthanum oxide-carrying or lanthanum hydroxide are as dephosphorization adsorbent.However, above inhale Attached dose relatively low to the adsorbance of phosphorus, is below 70mg P/g adsorbents.The main reason for phosphorus adsorbance is low include：Charcoal, Mostly in micro-meter scale, these carrier dimensions are excessive to be unfavorable for surface lanthanum and phosphoric acid piece-root grafting for expanded graphite and Coaseries kaolin etc. It touches；In addition zeolite is microcellular structure, and lanthanum load is easy to block duct, hinders absorption of the lanthanum to phosphate radical.Therefore it is badly in need of lanthanum-carried Adsorbing agent carrier with higher phosphorous adsorbance afterwards.
Galapectite is nanotube-shaped aluminosilicate mineral material, and outstanding feature is in nanoscale, and has special Jie Hole and hollow tubular structure.In addition, compared with the materials such as zeolite and activated carbon, galapectite is cheap, is used for Phosphateadsorption Cost is relatively low.It is mainly used for medicament slow release and gas catalytic field currently as the galapectite of carrier, but in Phosphateadsorption side Face has not been reported.
