Abstract
The invention is about the process and the equipment for the magnetic ion exchange resin of nuclear shell structure. The resin includes: magnetic particle, embed material and the active element. The magnetic particle is dispersed in the organic grain, outside of it is adhered the resin shell.
Description
[technical field]
The present invention relates to a kind of ion exchange resin and technology of preparing thereof, more particularly, the present invention relates to a kind of magnetic ion exchange resin and preparation method thereof and device.
[background technology]
Since phenol aldehyde type ion exchange resin had been synthesized in nineteen thirty-five Adams and Holmes research, 60 years of development courses had been experienced in the application of ion exchange resin.Various types of ion exchange resin occur in succession, enlarging day by day etc. of the continuous improvement of utilisation technology, range of application all shown huge prospects for commercial application and the market potential that ion exchange resin had.At present, the range of application of ion exchange resin is developed in the fields such as current chemical industry, electric power, electronics, environmental science, hydrometallurgy, analytical chemistry, food-processing, medical medicine by initial water treatment industry, has formed the chemical industry operation unit of a uniqueness.But common ion exchange resin exists some shortcomings that are difficult to overcome, and promptly stable inadequately in acid or alkaline medium, exchange capacity descends in the course of the work.In addition, if when containing a certain amount of suspended solids or muddy heavy-gravity slurry in the pending industry solution, mine smelting process for example is admittedly consolidate/separate the very difficulty that just becomes between alternate solid/liquid separation of ordinary resin and solution two and ordinary resin and the suspended solids; Also have, for ion exchange resin, the particle diameter that reduces resin can improve its speed of action, but also can bring, easily slagging scorification and be difficult to carry out problem such as post-processing operation big such as sedimentation difficulty, bed pressure drop simultaneously.
In order to address these problems, the ion exchange resin that exploitation has magnetic is ideal comparatively.For example, for the higher system of solids content, as long as suitable magnetic field is set at fluid outlet, magnetic ion exchange resin can be collected easily, sent for regeneration and recycling then, therefore magnetic ion exchange resin can be in order to handling the various liquid that contain solid matter, and such as the no isolation of purified of the enrichment that is used for mining site waste water minute amount of noble metal, life and industrial sewage etc., these all are that ordinary resin is difficult to realize.
Since last century the seventies, Australian Bolto etc. have delivered some about magnetic resin development reports with application, and countries such as the Soviet Union and India have also carried out development research to magnetic resin.Domestic scientific and technical literature has also been reported the preparation method of some magnetic ion exchange resins.
Wherein as two authors of Lin Like, Yang Chaoxiong of Guangzhou Inst of Chemistry, Chinese Academy of Sciences in " ion-exchange and absorption " 1990, deliver the paper of exercise question on 6 (1) publications, introduce it and fluoridize two iron, 4 ethene triamine ton phenol 4 with γ-three and encircle fluoro-resin and synthesized the epoxy group(ing) deacidite first for " epoxy group(ing) magnetic ion exchange resin synthetic with characterize ".Real dangerous result shows that magnetic resin microballoon size and loading capacity have determined the various factors in the resin manufacture process.The fluorine-based acidic resins mean diameter of a collection of typical ring is that 0.15mm, loading capacity are 3.3meg/g-r, and carbonation rate is 8.2emu/g-r, and is stable in acidity or alkaline medium.Experimental data has confirmed that also this is the good resin of a class, has suitable sequestering power to Zn, Cd, Hg, Co, Ni, Pb and other divalent cations.But do not adsorb alkaline-earth metal ions, this is identical with the polycaprolactam polyamine resin.
Woods is made every effort to overcome, these two authors of Yang Chaoxiong deliver the paper that exercise question is " cellulose-Based Magnetic Ion Exchange Resin " again on " ion-exchange and absorption " 1993,9 (6) publications, introduces it and will contain Fe

3The cellulose xanthogenate sodium (viscose glue) of powder is scattered in the oil under the high-speed stirring, is shaped 80～100 ℃ of dehydrations, makes the magnetic resin of particle diameter＜150 μ m.Studied and discussed of the influence of factors such as magnetic, oils, tensio-active agent and stirring velocity in the text to resin particle diameter and distribution thereof.
Patent documentation in this regard such as application number are that 91100655.9 Chinese patent discloses a kind of method for preparing magnetism macroporous adsorbed ion exchange resin, and this method is to adopt the temperature-gradient method polymerization procedure, adds hydro carbons pore-creating agent, ester analog assistant in prescription.It has solved the difficult point that magneticsubstance is difficult for encasing in the prior art, make magneticsubstance evenly successfully be embedded in the high polymer micro balloons, be prepared into and have permanent macroporous structure, the resin that has magnetic, adsorptivity and ion exchangeable simultaneously, it is said that this product can be widely used in that thermopnore carries out that separating substances is refining, decolouring, clarification and in environmental protection, carry out being used in wastewater treatment and the biochemical engineering purifying, for the automatization and the scale operation that separate, purify provide good condition.
Also having application number in above-mentioned field is that 03130423.0 Chinese patent file discloses a kind of ferromegnetism urea-formaldehyde resin microballoon medium and preparation method thereof, the base material of microballoon medium is the urea-formaldehyde resin of particle diameter at 0.5-20 μ m, and particle diameter is arranged is the Fe of 0.1-200nm to homodisperse in this base material
