Nws tau nkag siab tias cov organic dyes yog cov xim uas siv ntau tshaj plaws thiab tau siv dav hauv kev lag luam, kev tshawb fawb tshawb fawb, thiab ntau yam ntawm lub neej niaj hnub. Dyes ua rau peb cov khaub ncaws, khoom noj, thiab khoom siv niaj hnub muaj yeeb yuj; Dyes emit lub teeb nyob rau hauv lub microscope kom ua tiav cov duab, pab peb qhia paub tsis meej ntawm lub ntiaj teb microscopic. Cov ntaub ntawv qhia tau hais tias lub ntiaj teb no ntau lawm ntawm cov organic dyes tau mus txog 700000 tons ib xyoo, uas ze li ntawm 10-15% yog tso tawm mus rau hauv industrial thiab tsev neeg cov dej khib nyiab, dhau los ua ib qho tseem ceeb ntawm cov dej paug thiab ua rau muaj kev hem thawj rau ecological ib puag ncig thiab pej xeem. noj qab haus huv.
Cov kev kho mob uas twb muaj lawm rau cov dej khib nyiab, xws li coagulation flocculation thiab biodegradation, tuaj yeem tshem tawm feem ntau ntawm cov organic dyes hauv cov dej khib nyiab. Txawm li cas los xij, cov txheej txheem no tseem ntsib teeb meem xws li kev tshem tawm cov xim tsis tiav, txwv tsis pub cov dyes tsim nyog, thiab muaj peev xwm ntawm cov pa phem thib ob los ntawm cov sludge generated. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm nanotechnology thiab cov khoom siv thev naus laus zis, qee cov ntaub ntawv tawm tshiab thiab cov thev naus laus zis kho cov dej khib nyiab tau tshwm sim, suav nrog catalytic oxidation, nanofiltration, thiab ntxeem tau particle adsorption. Catalysts, daim nyias nyias, thiab cov khoom siv adsorption tuaj yeem rov qab siv dua tom qab ua tiav cov dej khib nyiab, tab sis qhov rov qab ntawm cov dyes tsis tshua muaj nuj nqis. Yog vim li cas rau qhov no yog tias nyob rau hauv cov txheej txheem ntawm cov organic dye desorption, eluents uas muaj inorganic acids, bases, los yog ntsev feem ntau yog ntxiv rau cov aqueous tov, ua rau cov txheej txheem rov qab ntawm cov organic dyes complex.
Nyob rau hauv xyoo tsis ntev los no, Wang Shutao cov kev tshawb fawb pab neeg tau npaj ib txoj kev tshiab ntawm cov tshuaj pleev ib ce interfacial polymerization los ua ke heterostructure microspheres, thiab tau ua ib tug series ntawm tshiab achievements nyob rau hauv nws npaum li cas sib cais thiab daim ntawv thov. Muaj ntau hom tshuaj pleev ib ce interfacial polymerization synthesis txoj kev tau tsim, thiab ib tug series ntawm heterogeneous microspheres nrog ntau qhov sib txawv, tshuaj muaj pes tsawg leeg, pores, thiab nto nanostructures tau npaj. Kev sib cais ntawm kab glycopeptides nyob rau hauv complex biological fluids, proteins ntawm qhov ntau thiab tsawg, cov kab mob nucleic acids, kab mob qog hlwb nyob rau hauv peripheral cov ntshav ntawm cov neeg mob qog noj ntshav, thiab cov roj tee hauv dej tau pom. Cov kab chromatographic, kab sib txawv, microfluidic Separation li xws li ntawv chromatography. Raws li cov kev tshawb fawb tshawb fawb no, kuv tau raug caw los sau ib tsab xov xwm tshuaj xyuas.
Siab dispersed hydrophilic hydrophobic heterogeneous microspheres
Qhov saum npoo ntawm hydrophilic hydrophobic heterogeneous microspheres muaj alternating hydrophilic thiab hydrophobic Cheebtsam, uas yog conducive mus rau kis ntawm siab polar solvents (dej), nruab nrab polar solvents (organic solvents xws li ethanol), thiab tsawg polar solvents ( oily organic solvents xws li octane. ). Tsis tas li ntawd, nyob rau hauv cheeb tsam hydrophilic, nws yog ib qho yooj yim los qhia cov pab pawg, uas muaj peev xwm muab electrostatic repulsion ntawm hais thiab ua tau zoo dispersion nyob rau hauv sib txawv solvents. Los ntawm kev siv qhov tshwj xeeb no tag nrho dispersion, pab neeg no tau tsim ib lub tswv yim rau kev sib cais thiab rov qab dyes los ntawm cov dej khib nyiab uas muaj cov organic dyes. Cov dyes yog adsorbed mus rau microspheres hauv dej, dej huv yog tau los ntawm kev pom, thiab microspheres nrog adsorbed dyes yog dispersed rau hauv cov kuab tshuaj organic kom ua tiav cov xim desorption. Organic solvents nrog yaj dyes yog tau los ntawm kev pom, thiab cov dyes tau zoo los ntawm distillation, thaum lub microspheres raug siv dua.
Hydrophilic hydrophobic heterogeneous microspheres muab cov khoom cog lus rau kev rov qab los ntawm cov organic dyes. Nyob rau hauv tus txheej txheem ntawm recycling organic dyes, tsuas yog cov organic solvents yuav tsum tau ntxiv, tsis tas yuav ntxiv eluents uas muaj inorganic acids, bases, los yog ntsev. Cov kuab tshuaj organic tau yooj yim tshem tawm ntawm cov dyes los ntawm kev sib cais yooj yim, zam cov kauj ruam nyuaj ntawm kev tshem tawm cov inorganic acids, bases, thiab ntsev. Cov khoom siv no muaj cov ntawv thov dav dav hauv kev sib cais thiab kev soj ntsuam ntawm cov qauv nyuaj xws li kev kho ib puag ncig muaj kuab paug, kev rov ua dua tshiab, cov peev txheej marine enrichment thiab extraction, thiab tshawb nrhiav biomolecular.
