Txog Txheej Txheem Ntau Lawm:
Xav paub ntau ntxiv txog UVC LED:
1. Thaum Ultraviolet (UV) hluav taws xob tau siv los kho cov dej, cov dej puas dhau los ua hluav taws xob?
Koj tsuas yog tsis meej pem txog lo lus&"hluav taws xob &". Kuv nyiam siv lo lus&"UV teeb &" es tsis yog&"UV tawg &"; rau qhov laj thawj uas koj tsis meej pem. Ultraviolet yog" lub teeb" - koj tuaj yeem' tsis pom nws vim tias peb lub qhov muag tsis nkag siab UV; Txawm li cas los xij, nws yog lub teeb pom kev zoo nrog lub wavelengths dhau ntawm&"violet &"; kawg (vim li no lub sij hawm" ultraviolet") ntawm zaj sawv spectrum.
Txij li UV yog" lub teeb&";, nws taug kev los ntawm huab cua thiab dej ntawm qhov nrawm ntawm lub teeb thiab thaum lub teeb ci UV raug tua, UV ploj mus. Tsis muaj" seem" thiab cov dej uas tau raug rau UV yog tib yam li nws tau ua ntej raug, thiab yeej tsis yog dej&"; radioactive &";. Nws zoo li ci lub teeb ci rau hauv ib khob dej. Kuv xav tias koj yuav pom zoo tias thaum koj tua lub teeb, dej tsis tau hloov.
Cov chav dej tua kab mob UV tau tsim los muab kom txaus" UV koob tshuaj&"; yog li ntawd ib qho kab mob me me hauv dej tau ua&"tsis ua haujlwm &". Dab tsi tshwm sim yog tias UV tau nqus los ntawm DNA hauv cov kab mob me me; DNA raug puas tsuaj kom cov kab mob me me tsis tuaj yeem tsim tawm. Cov cell uas tsis tuaj yeem tsim tawm tsis tuaj yeem ua rau muaj kab mob. Qhov zoo nkauj tshaj plaws ntawm UV yog qhov nws ua nws txoj haujlwm thaum cov dej hla dhau chav tsev, tab sis tom qab cov dej tau dhau los, nws tau&"tua kab mob &";, tab sis nws&"; dej zoo" tsis tau hloov
2. Kuv nkag siab ib tus xav tau 1/100 ntawm watt-thib ob ib square cm rau kev lim dej siv 254 nm UV. Qhov ntau npaum li cas rau huab cua?
Tam sim no lub koom haum tswj hwm feem ntau hais qhia kom paub meej lossis siv tshuaj UV ntawm 40 mJ/cm2 (nco ntsoov tias 1 mWs=1 mJ) kom ntseeg tau tias tsawg kawg 4 lub cav tsis ua haujlwm ntawm txhua yam kab mob. Txij li qhov npliag lossis UV koob tshuaj thov yog ywj siab ntawm qhov nruab nrab, qhov xav tau no tseem yuav siv rau huab cua. Txawm li cas los xij, Kuv tseem tsis tau paub txog ib txoj cai twg tseem hais txog kev kho cua UV.
3. Zam txim dab tsi uas yuav yog lo lus nug tsis txawv: Kuv tab tom txiav txim siab siv UVC qhov muag tshuaj tua kab rau oxidizing saum ntoo. Qee tus ntawm kuv cov phooj ywg tau siv qhov muag teev UVB ntau xyoo los tsim' tanned' saum npoo av kom pom cov ntoo tshiab, kom muab nws dhia-pib hauv nws cov txheej txheem kev laus, tab sis kuv zoo li xav tias xav tau kev kho mob hnyav dua, thiab thaum kawg yuav nyiam paub qhov twg yog qhov zoo tshaj rau cov txheej txheem no. Kuv yuav tsis nyob tam sim no thaum lub teeb yuav ua haujlwm, thiab yuav tsum tsis muaj' tsis yog teeb meem kev nyab xeeb; tsuas yog xav tau rau qhov hnyav tshaj plaws oxidizing raug tau, hauv lub sijhawm luv tshaj plaws. Wavelength twg yog rau kuv? Txog cov ntaub ntawv, Kuv' ma ua nkauj ua suab paj nruag hneev, thiab ob lub tshuab ua nkauj laus ncas thiab cov kws ua hneev nyob hauv ib puas xyoo dhau los tau yooj yim dai lawv cov khoom sib dhos tseem tsis tau ua tiav thiab hneev nyob hauv eaves kom pom lawv ncaj qha tshav ntuj rau 6 lub hlis rau qhov txiaj ntsig xav tau, tab sis tsis tas yuav hais qhov no tsis yog txoj hauv kev tsim nqi ntawm nkauj laus ncas lossis hneev taw ntau lawm hauv tiam 21st century. Lwm txoj hauv kev yog ncaj qha nitric acid, lossis nitric acid fuming, tab sis qhov ntawd muaj qhov cuam tshuam tsis zoo rau kev noj qab haus huv, thiab kuv yuav zam nws yog tias kuv ua tau.
Zoo, qhov no yog lo lus nug nthuav! nws lo lus" oxidation" tuaj yeem txhais ntau yam:
Cov tshuaj tiv thaiv nrog cov pa kom tsim tau ntau dua&& quot; oxidized&& quot; sib xyaw (piv txwv li, oxidation ntawm methanol rau formaldehyde).
Ua kom muaj cov lej oxidation ntawm cov khoom [piv txwv li, hloov pauv ntawm Fe (II) rau Fe (III)]
Ua kom tiav cov ntxhia ntawm cov organic sib txuas los tsim CO2, H2O thiab cov kua qaub rau txhua Cl, N, P, S, thiab lwm yam.
Direct photolysis ntawm qhov sib xyaw {piv txwv li, photolysis ntawm nitrosodimethylamine [(CH3) 2N-NO]}.
Kuv xav tias koj tab tom hais txog thawj lub ntsiab lus, hais txog&"tanning &"; ntoo.
Ntoo yog cov txheej txheem organic nyuaj heev nrog ntau yam khoom uas nqus tau UV. Txawm li cas los xij, tsis yog txhua qhov kev nqus UV ua rau cov tshuaj tiv thaiv kab mob (photochemistry). Feem ntau cov tshuaj tiv thaiv kab mob tshwm sim ntawm nthwv dej tsawg dua 300 nm (muaj ntau qhov kev zam, piv txwv li, photosynthesis, uas ua haujlwm nrog pom lub teeb mus txog 700 nm). Yog li ntawd, kuv xav tias qhov teeb meem UV zoo tshaj plaws rau koj lub hom phiaj yuav yog&"tua kab mob &"; UV teeb, xws li lub teeb hluav taws xob qis (tso tawm ntawm 254 nm) lossis lub teeb nruab nrab nruab nrab siab (tso tawm ntau ntawm 200-400 nm hauv UV). Lub teeb qis qis yog lub zog qis (lub teeb ntev 1.2 m muaj lub zog kwv yees li 40 W). Cov roj teeb nruab nrab muaj zog dua (piv txwv li, lub teeb 10 cm muaj lub zog kwv yees li 1 kW)." UV effect" yuav tsim tawm ntawm tus nqi uas kwv yees li sib npaug rau lub zog ntawm lub teeb (muab qhov deb mus rau&"; phiaj" yog tib yam).
Koj yuav pom tias kev kho mob ua ntej nrog hydrogen peroxide yuav txhim kho" UV effect&";, txij li photolysis ntawm H2O2 tsim cov tshuaj hydroxyl radicals (Â · OH), tus neeg sawv cev oxidizing muaj zog heev.
Koj hais txog" kev nyab xeeb", thiab kuv tsis tuaj yeem hais meej txaus tias koj yuav tsum tau muab cov chav tso hluav taws xob tag nrho kom tsis txhob muaj tawv nqaij lossis qhov muag raug rau leej twg. UV tsis zam txim rau qhov zoo li no.
