Na li khahloa ke ponahalo ea lintho kapa lisebelisoa tsa metsi tse khanyang lefifing ka khalase? Na u batla ho tseba ho etsa mokelikeli o khanyang ka matsoho a hao? Ke tla tlameha ho utloisisa. Hopola hore ho etsa mokelikeli o khanyang ka tlung hase ntho e bonolo ka ho fetisisa, mme ka ho fetisisa e sa hloeke haholo, kahoo o tla tlameha ho hlatsoa lijana ka mor'a liteko.
Joang ho etsa metsi a khanyang ka matsoho?
Ho totobetse hore mokelikeli ona o lefifi lefifing ka lebaka, ho hlakile hore tse ling tsa lik'hemik'hale li ntse li etsahala. Re ke ke ra kenella ka hare ho k'hemistri, re mpa re e nka e le hore lintho tse ling tikolohong ea acidic li qala ho hlahisa leseli. Kahoo, e le hore tsohle li hlokahale, ho hlokahala hore u lokise li-reagents tse hlokahalang. Kakaretso ea metsi a khanyang ha a le mong, ka hona, nahana ka litsela tse 'maloa tsa ho e lokisetsa.
Tsela ea 1
U tla hloka:
- luminol (e rekisoang mabenkeleng ho rekisa lik'hemik'hale tsa lik'hemik'hale) - 2-3 g;
- Hydrogen peroxide 3% (ho tswa ho k'hemistri) - 80 ml;
- metsi 100 ml;
- koporo ea sulfate (ferric chloride, letsoai le khubelu la letsoai) - 3 g;
- Tharollo ea soda e soda - 10 ml;
- Mefuta ea li-fluorescent - rubri, tala e khanyang, joalo-joalo.
- li-tubes tsa teko (likhase, likhalase tsa khalase tse hlakileng).
Khoebo
- Powoline ea Luminol e mosehla, e leng tharollo e putsoa le e se nang lehlakore e qala ho khanyang ka botala. Kahoo ha se lefeela hore e le sebakeng sa pele ho risepe, ntle le luminol teko e ke ke ea atleha. Tšela metsi ka botlolo, qhala ho eona luminol.
- Eketsa hydrogen peroxide ho botlolo.
- Ha re le moo re romela sulphate ea koporo kapa tšepe ea ferric, kapa letsoai le khubelu. Haeba ho ne ho se na e mong, kapa e mong, kapa oa boraro, ho ka khoneha ho etsa le mekhoa e ntlafalitsoeng. Squeeze mali a seng makae ka mokotleng oa khoho, o noe metsi ebe o eketsa 1 tbsp. khaba ea tharollo ena ho motsoako ka botlolo.
- Eketsa soda le ho feta ho botlolo.
- Tlosa leseli mme u khahloe ke khanya e hlollang ea buluu e tsoang ho tleloubu.
- Haeba mmala o moputsoa ha o eo (ho na le batho ba joalo), joale eketsa tee efe kapa efe ea fluorescent ho tharollo ka botleng.
Tsela ea 2
U tla hloka:
- luminol - 0,1 g;
- e omileng alkali (KOH) - 35 g;
- dimethoxide (dimethylsulfoxide) - 30 ml;
- botlolo e nang le li-coch tsa 500 ml;
- dae ea fluorescent.
Khoebo
- Re kopanya ka botlolo luminol, alkali le dimexide.
- Koala botlolo ka sekwahelo ebe oa e sisinya.
- Ho tla ba le botala ba 'mala o putsoa, o ka lokisoang, o eketsa ho hlophisoa ha dae ea fluorescent.
- Haeba khanya e fokola, bula sekwahelo, u kene ka moea o monyenyane ka har'a flask. Eaba mokelikeli o qala ho hlahisa leseli hape.
Mokhoa oa 3
U tla hloka:
- khalase e telele - 1 pc.;
- tharollo ea li-detergent - 20 ml;
- hydrogen peroxide 3% - 10 ml;
- tharollo ea luminol 3% - 5 ml;
- likristale tse 'maloa tsa potassium permanganate.
Khoebo
- Tšela tharollo ea sesepa ka khalase.
- Moo re boetse re romella tharollo ea hydrogen peroxide le luminol.
- Ka khethollo, re roala likristale tse ngata tsa potassium permanganate (potassium permanganate) hape re li romela khalase.
- Ha o leka ho kopanya, motsoako o tla fofa, 'me o tla phatsima hantle.
Empa, joalokaha ho se ho boletsoe ka holimo, kamora liteko tsohle li lokela ho hloekisa lapeng le ho hlatsoa lijana. Empa hape ts'ebetso ena e ka etsoa e tsotehang haeba u robala kamoreng. Tlas'a tšusumetso ea metsi a pompo ea chlorinated, lisebelisoa tsa luminol li qala ho khanyetsa.
Joang ho etsa phosphor?
Ho etsa metsi a khanyang hona joale ho utloahala, empa haeba motho e mong a batla ho latela tsela ea setsebi sa k'hemistri ka nakoana, joale u ka leka ho etsa phosphor. E le hore re etse sena, re reka ka pharmacy coniferous concentrate le boric acid. Qolla ligrama tse 1 tsa coniferous tse tsepamisitsoeng metsing. Nka khaba u behe oli ea boric ho eona. Eketsa tharollo ea coniferous ho tsepamisa mohopolo ka ho theola khaba le ho e kopanya ka bonolo. Re pheha mollo, ho fihlela tharollo e pheha ka khaba, lithupa li phunya ntho e bohale. Ho eketsa, eketsa e 'ngoe tharollo le ho futhumala hape. E fetoha ntho e mosehla - phosphor. Ka mor'a ho ba leseli le khanyang (o ka sebelisa leseli) o tla khantša lefifing, empa eseng nako e telele, metsotsoana e mengata.
