Abstract
The invention discloses a magnetic fluorine ion adsorbent and a preparation method thereof. The magnetic fluorine ion adsorbent comprises the following three components at the same time: Fe3O4, ZrO2-CeO2 composite and La2(C2O4)3. The preparation method comprises the following steps: dispersing nano-sized Fe3O4 of which the surface is modified by SiO2 and an auxiliary agent into deionized water containing ammonia water and ethanol, performing ultrasonic treatment, stirring and uniformly mixing, adding ZrOCl2.8H2O and Ce(NO3)3.6H2O, adding lanthanum nitrate after reaction, uniformly mixing, dripping an oxalic acid solution, and finally, collecting a product by using a magnet and washing and drying the product. The produced adsorbing material is regular in shape, can adsorb a large number of fluoride ions in water, is magnetic, and can perform solid-liquid separation conveniently by virtue of a magnetic force during either preparation of the material or the practical application; the adsorbent has a wide application prospect in an aspect of treating a large volume of high-concentration fluoride-containing wastewater.
Description
Technical field
The invention belongs to sorbing material technical field, be specifically related to magnetic fluorine ion absorber of a kind of tool and preparation method thereof.
Background technology
The fluorine disease of drinking high-fluorine water and causing be distribute in the world the most widely endemic disease this.There is underground water fluoride pollution in China, except Shanghai and Hainan, other provinces，municipalities and autonomous regions all have fluorine poisoning in various degree to occur comparatively at large.For the fluorine content in drinking water, have strict demand in the world, in World Health Organization's regulation drinking water, the safe level of fluorine is 0.6-1.5 mg/L, and in China's Drinking Water, the maximum permissible concentration of fluorine is 1 mg/L.Long-term drinking fluorinated volume can cause chronic fluorine poisoning higher than the high-fluorine water of 1.5 mg/L, and tooth, bone, nervous system, digestive system, respiratory system and reproductive system are produced and poisoned.Therefore, develop efficient fluorine removal technology very urgent.
In numerous drinking water defluorination methods, absorption method because it is simple, easy to operate, cost is low is considered to the most promising method.Aspect sorbing material, the fluorine ion absorption property of the materials such as oxide of rare earth and some transition metal obtains extensive concern, and the novel fluorine ion absorber based on this class developing material is just becoming current study hotspot.For example, patent [fluoride ion removing agent and the method for using the sewage that its processing contains fluorine ion, application number 01122878.4] proposed to contain a kind of aqueous hydrochloric acid solution of and calcium carbonate reaction and a kind of rare earth element as the fluoride ion removing agent of the aqueous solution of cerium, lanthanum or its mixture etc., but it also needs to utilize flocculant while using, thereby makes complicated operation; Patent [a kind of composite metal oxide de-fluoridation adsorbent, application number 200510116751.0] a kind of composite metal oxide de-fluoridation adsorbent proposed, it contains transition metal, aluminium and rare earth metal, aluminium is as the most effective one of the composition of this adsorbent, may cause the narrower and easy stripping intoxicating of aluminium of applicable pH range; Patent [attapulgite defluorination agent, 200510040604.x] a kind of adsorbent being comprised of active attapulgite clay, edible alum, calcium oxide, calcium sulfate and sym-closene proposed, although material cost is lower, but adsorbent adsorbance is less, and need the unit such as complicated flocculation, precipitation, clarification filtration to realize Separation of Solid and Liquid, complicated operation.
In addition, at present common fluorine ion absorber the means such as conventionally need be taked to filter, centrifugal and realize Separation of Solid and Liquid, and the recovery of adsorbing saturated adsorbent is wasted time and energy.And adsorbent has been enrichment but not degradation to pollutant, can not be separated from processed liquid up hill and dale fast after saturated if reach absorption, can cause secondary pollution to processed liquid.Magnetic adsorptive material can be promptly under the effect of externally-applied magnetic field by enrichment, thereby obtain effectively separated and reclaim, and easy and simple to handle.Magnetic fluorine ion absorber the present invention relates to and preparation method thereof contains Fe simultaneously
