Kev sib koom ntawm cov kev tshawb nrhiav uas nquag siv rau cov khoom siv tshuaj lom neeg
Thaum lub sij hawm tsim cov pa roj carbon monoxide thiab teeb meem, cov pa roj hauv lub rooj cob qhia yog cov pa paug, huab cua, plua plav, thiab lwm yam. Nyob rau hauv cov xwm txheej uas ntau tus neeg tsis tuaj yeem pom, nws tuaj yeem ua rau tib neeg lub cev tsis zoo. Cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm cov pa phem lawv tus kheej, qhov ntau npaum li cas, concentration, lub sijhawm ua haujlwm ntawm cov co toxins, thiab kev noj qab haus huv ntawm cov neeg ua haujlwm muaj feem cuam tshuam.
Nyob rau hauv qhov xwm txheej ntawm kev tsim kev puas tsuaj rau cov khoom siv roj
Thaum siv cov khoom siv tshuaj lom neeg los kuaj xyuas cov pa phem, kuj tseem muaj ntau yam kev tshawb nrhiav roj av muaj rau xaiv. Hnub no kuv yuav qhia rau koj paub ntau txoj hauv kev rau kev kuaj pom cov pa phem, vam tias yuav pab koj xaiv.
1. Colorimetric tube ntsuas tshuab: Ntxiv nrog rau kev siv tshuaj lom lub tswb ceeb toom, colorimetric raj ntsuas tshuab tseem yog cov tshuaj lom thiab teeb meem roj nrhiav kom tau siv hauv kev tiv thaiv ib puag ncig. Qhov kom zoo dua ntawm txoj kev ntsuas no raws li tshuaj lom neeg cov tshuaj tiv thaiv yog tias nws tuaj yeem them rau qhov tsis txaus ntawm kev ntsuas ntsuas uas tsis tsim nyog rau kev kuaj xyuas cov sensors.
2. Electrochemical sensor: Electrochemical sensor yog ib qho kev tshawb nrhiav thiab kev siv thev naus laus zis siv rau cov khoom siv hluav taws xob portable, ua kom yooj yim rau kev tshawb nrhiav cov pa phem thiab cov pa phem hauv ntau qhov xwm txheej. Electrochemical sensors muaj cov yam ntxwv ntawm qhov me me, kev siv hluav taws xob tsawg, rov ua haujlwm zoo, thiab lub neej ua haujlwm ntev.
3. Semiconductor sensors: Semiconductor sensors yog cov khoom kuaj xyuas ua los ntawm cov hlau oxides lossis hlau semiconductor oxide cov ntaub ntawv. Nws tuaj yeem tsim kev cuam tshuam ntawm qhov chaw adsorption thiab kev sib cuam tshuam ntawm cov pa roj, ua rau muaj kev hloov pauv hauv cov khoom siv hluav taws xob lossis voltammetry cov yam ntxwv ntawm cov peev txheej saum npoo av, uas yog tus cwj pwm los ntawm kev txav mus los, thiab tuaj yeem siv los txheeb xyuas qhov feem pua ntawm cov roj hluav taws xob.
Ua ntej xaiv cov khoom siv tshuaj lom neeg, kev txiav txim siab thiab kev txiav txim siab tuaj yeem ua raws li kev siv qhov xwm txheej thiab qhov xwm txheej ntawm cov pa phem.
