Yog lawv fascinated los ntawm cov spectacle ntawm cov khoom los yog kua luminous hauv maub hauv lub khob? Koj puas xav paub seb yuav ua li cas thiaj ua rau lub cev luminous nrog koj txhais tes? Zoo, Kuv yuav tsum to taub. Tsuas nco ntsoov tias ua kua qaub nplaum hauv tsev tsis yog qhov nyuaj, thiab qhov tseem ceeb tshaj plaws tsis huv, yog li koj yuav tsum ntxuav cov tais diav tom qab cov kev sim.
Yuav ua li cas ua kom muaj kua luminous nrog koj txhais tes?
Nws yog tseeb hais tias lub kua glows nyob rau hauv lub maub rau ib tug yog vim li cas, thaj ib co tshuaj lom neeg kev kawm yog qhov chaw. Peb yuav tsis mus tob rau hauv chemistry, peb tsuas yog siv raws li ib qho kev qhia tias qee yam tshuaj nyob rau hauv ib qho chaw acidic pib tawm lub teeb. Yog li, thiaj li ua tiav rau txhua yam uas tsim nyog yuav tshwm sim, nws yog qhov tsim nyog los npaj cov tshuaj reagents. Daim ntawv qhia rau cov kua qaub nplaum tsis nyob ib leeg, yog li xav txog ntau txoj kev los npaj nws.
Txoj Cai 1
Koj yuav tsum tau:
- luminol (muag nyob rau hauv cov khw muag tshuaj chemical reagents) - 2-3 g;
- hydrogen peroxide 3% (ntawm lub tsev muag tshuaj) - 80 ml;
- dej 100 ml;
- tooj liab sulfate (ferric chloride, liab ntshav ntsev) - 3 g;
- daws ntawm caustic dej qab zib - 10 ml;
- Fluorescent dyes - rubren, ci ntsa iab ntsuab, thiab lwm yam.
- kev ntsuas plawv (flasks, pob iav pob tshab).
Kev tsim
- Luminol hmoov yog daj, uas nyob rau hauv xiav thiab nruab nrab daws pib ci rau hauv xiav. Yog li ntawd nws tsis yog nyob rau hauv vain hais tias nws yog nyob rau hauv thawj qhov chaw nyob rau hauv daim ntawv qhia, tsis muaj luminol qhov kev sim yuav tsis ua tiav. Ncuav dej mus rau hauv lub hwj, dissolve nyob rau hauv nws luminol.
- Ntxiv hydrogen peroxide rau lub khob haus dej.
- Muaj peb xa cov tooj liab sulphate lossis ferric iron, los yog ntshav liab ntsev. Yog tias tsis muaj ib qho twg, tsis yog lwm tus, los yog tus thib peb, nws yog ib qho ua tau los ntawm kev tsim kho. Nyem me ntsis ntshav los ntawm nqaij qaib thim, dilute nws nyob rau hauv dej thiab ntxiv 1 tbsp. diav ntawm no daws mus rau sib tov nyob rau hauv ib lub hwj.
- Ntxiv cov dej cawv caustus rau lub khob haus dej.
- Taws lub teeb thiab qhuas tus txheej txheem xiav uas ci ntsa iab ntawm lub teeb.
- Yog hais tias xim xiav tsis yog rau koj (muaj cov neeg zoo li no), tom qab ntawd ntxiv cov xim fluorescent rau cov kua hauv lub hwj.
Txoj Kev 2
Koj yuav tsum tau:
- luminol - 0.15 g;
- qhuav alkali (KOH) - 35 g;
- dimethoxide (dimethylsulfoxide) - 30 ml;
- ib lub hwj nrog ib tug 500 ml cork;
- fluorescent zas.
Kev tsim
- Peb sib tov nyob hauv cov roj luminol, alkali thiab dimexide.
- Kaw lub hwj khob nrog lub hau thiab co nws.
- Yuav muaj kev xoos ntawm xiav xim, uas muaj peev xwm rov qab tuaj ntxiv, ntxiv mus rau qhov muaj pes tsawg leeg uas muaj fluorescent zas.
- Yog hais tias glow yog tsis muaj zog, qhib lub hau, cia nyob rau hauv ib tug me ntsis huab cua nyob rau hauv lub flask. Thiab tom qab ntawd ces lub cev pib ua kom pom dua.
Txoj Cai 3
Koj yuav tsum tau:
- ib lub iav siab - 1 pc .;
- tshuaj txhuam cev - 20 ml;
- hydrogen peroxide 3% - 10 ml;
- daws ntawm luminol 3% - 5 ml;
- ob peb iav ntawm poov tshuaj permanganate.
Kev tsim
- Ncuav kua tshuaj rau hauv lub khob.
- Muaj peb kuj xa hydrogen peroxide thiab luminol tov.
- Cais, peb tsom ob peb iav ntawm poov tshuaj permanganate (poov tshuaj permanganate) thiab tseem yuav xa nws mus rau ib khob.
- Thaum koj sim sib tov, qhov sib tov xyaw yuav ua npuas, thiab nws yuav ci ntsa iab.
Tab sis, raws li tau hais saum toj no, tom qab tag nrho cov kev sim yuav tsum ntxuav hauv tsev thiab ntxuav cov tais diav. Tab sis qhov no kuj ua rau muaj kev txaus siab yog tias koj ntxoov ib chav. Nyob rau hauv tus ntawm chlorinated siv dej, luminol daws pib ci.
Yuav ua li cas ua kom muaj phosphor?
Yuav ua li cas ua kom muaj kua luminous yog tam sim no to taub, tab sis, yog hais tias ib tug neeg xav ua raws li txoj kev ntawm ib tus kws tshuaj ntsuam me ntsis ntxiv, ces koj yuav sim ua tus phosphor koj tus kheej. Ua li no, peb yuav nyob rau hauv lub tsev muag tshuaj coniferous mloog zoo thiab boric acid. Dissolve 1 gram ntawm coniferous mloog zoo nyob rau hauv dej. Siv ib rab diav thiab muab ib co boric acid rau nws. Ntxiv ib qho kev daws ntawm coniferous mloog zoo los ntawm poob rau hauv ib lub diav thiab maj mam to mix nws. Peb boil tshaj qhov hluav taws kub, kom txog thaum kev daws boils nyob rau hauv rab diav, npuas txav ib yam dab tsi ntse. Txias, ntxiv lwm cov kua thiab sov dua lub zog. Nws hloov tawm ib cov daj tshuaj - ib phosphor. Tom qab nyob hauv lub teeb ci (koj siv tau lub flash) yuav ci hauv maub, tiam sis tsis ntev, ob peb feeb.
