Description
Technical field
The present invention relates to new material technology field, specifically, is a kind of new material with resin-coating silica gel characteristic.
Background technology
Some that new material refers to newly-developed or that researching and developing, to have preeminent performance materials, have the performance more more excellent than traditional material.New material technology is then the will according to people, by a series of research process such as physical study, design of material, materials processing, test evaluations, creates the technology of the new material that can meet various needs.
Along with scientific technological advance, people, on the basis of traditional material, according to the achievement in research of modern science and technology, develop new material.New material is metal material, Inorganic Non-metallic Materials (as pottery, gallium arsenide semiconductor etc.), the large class of high-molecular organic material, advanced composite material four by component.Structural material and functional material is divided into by material property.Structural material mainly utilizes mechanics and the physicochemical property of material, to meet the performance requirements such as high strength, high rigidity, high rigidity, high temperature resistant, wear-resisting, anti-corrosion, Flouride-resistani acid phesphatase; The effect such as electricity, magnetic, sound, photo-thermal that functional material mainly utilizes material to have, to realize certain function, as the nuclear material etc. of semi-conducting material, magnetic material, light-sensitive material, thermo-sensitive material, stealth material and manufacture atom bomb, hydrogen bomb.New material acts on great in national defense construction.Such as, hyperpure silicon, GaAs are succeeded in developing, and cause birth that is extensive and super large-scale integration, make the operational speed of a computer bring up to more than 10,000,000,000 times per second from hundreds of thousands per second; The operating temperature of materials for aeroengines often improves 100 DEG C, and thrust can increase 24%; The infra-red radiation of stealth material energy electromagnetic wave absorption or reduction weaponry, makes enemy's detection system be difficult to find etc.
One of Main way of 21 century development in science and technology is the development and application of new material.The research of new material is that the mankind march to deeper physical property understanding and application.
Along with the progress of science and technology, fabrics for industrial use new material constantly presents development trend, and purposes is also continuous to be expanded to multiple fields.Some have the fiber of specific function as aramid fiber, polyphenylene sulfide, carbon fiber etc., although price is more expensive, are still had an optimistic view of by market in fields such as environmental protection, energy-saving and emission-reduction, flame-resistant high-temperature-resistants.
New material is as the basis of new and high technology and guide, and range of application is extremely extensive, and its same information technology, biotechnology become 21st century most important and the most potential field together.The same with traditional material, the multiple different angles such as new material can form from structure, function and application field are classified to it, mutually intersect with nested between different classification, generally by application and current study hotspot, new material be divided into following major domain:
Electronic information material, new energy materials, nano material, advanced composite material, advanced ceramics material, ecological environment material nd, new function material (containing high temperature superconducting materia, magnetic material, diamond thin, functional high molecule material etc.), bio-medical material, high performance structures material, intellectual material, novel building and new chemical materials etc.
New material is a kind of widely used Sample Pretreatment Technique filler, Sample Pretreatment Technique is SPE general principle is have with Stationary liquid in sample to retain on solid-phase extraction column compared with the component of high forces, and the component more weak with Stationary liquid active force flows out solid-phase extraction column very soon, thus reach separation object.
The more SPE material of current use mainly contains the large class of bonded silica gel SPE material, inorganic matrix SPE material, organic polymeric solid phase fiber material and mixed type SPE material 4.
Wherein using maximum is carbon 18 bonded silica gel solid-phase extraction column, generally regarded universal adsorbent, can from the aqueous solution adsorb organic compound, be especially suitable for organic desalination, its major defect be selective low, to strong polarity and aqueous samples retain weak, volume containing the sample is low, dust removal rate is low.
Inorganic matrix solid material is inorganic oxide and graphitized carbon class inorganic matter mainly, and the common feature of these inorganic material is that surface has activity hydroxy, is mainly used in positive extraction.
Organic polymeric solid phase fiber material with polystyrene divinyl benzene resin (PS) for matrix carries out modification; in recent years; new high-crosslinking-degree polymer resin SPE material is constantly had to put on market, as containing methylol, benzoyl and adjacent carboxylbenzoyl, sulfonic group, trimethylamine etc.These modified resin have good hydrophily, can obtain the higher rate of recovery when extraction water Semi-polarity compound.
2 kinds or two or more sorbing material layering are mainly inserted solid-phase extraction column by mixed type SPE material, reach under the prerequisite of not losing target compound, utilize the characteristic of mixed type solid-phase extraction column different functional groups, by the object regulating the pH value in extraction process to remove sample substrate ionic and nonpolar chaff interference respectively.
But above material has its defect, there is silica gel for high ph-values analysis and dissolve dangerous in silica gel material; The feature that resin material pore-size distribution is too wide and mechanical strength is bad; Inorganic material range of application is narrower.
