Peb txhua tus nyob hauv tsev muaj cov khoom muaj mercury. Piv txwv li, cov ntsuas kub uas ntsuas kub nyob hauv chav, khoom siv kho mob, lub zog txuag cov fluorescent teeb. Cia peb paub yuav ua li cas txaus ntshai yog qhov tawg thermal lub rooj zaum lossis muaj teeb meem fluorescent hauv txhua lub tsev?
Hauv tus pas ntsuas kub ib txwm muaj txog li 2 g ntawm cov mercury, hauv lub zog txuag teeb tsis ntau tshaj 2.5 mg, i.e. Yuav luag 1000 zaug tsawg dua.
Yog li ntawd, nws yuav muaj cai tias muab faib ib lub teeb ntawm tus neeg siv khoom hauv tsev tsis yog txaus ntshai heev. Txawm li cas los xij, tej zaum txhua tus paub tias Mercury yog hlau. Tab sis ntau tsis nco qab tias nws txaus ntshai heev. Ua ntej tshaj plaws, nws evaporation yog txaus ntshai. Mercury evaporates nyob rau hauv chav tsev thiab txawm tias xoom. Cov cim ntawm kev lom tau pom nyob rau nruab hnub thiab tau qhia nyob rau hauv dav dav tsis muaj zog, mob taub hau, mob thaum nqos, nce ntxiv.
Kuv yuav ua li cas yog tias tus pas ntsuas kub lossis lub teeb ci lumnetic lossis lub teeb ci ntsa iab?
Kev cuam tshuam yog ntsuas kom tshem cov mercurch tshuab, physicochemical lossis cov qauv siv tshuaj.
1. kev
Ua ntej tshaj plaws, tam sim ntawd qhib tag nrho cov qhov rai thiab qhov rooj, hais kom txhua tus tawm ntawm chav tsev thiab nqa tawm cov tsiaj. Thaum nqa tawm, qee qhov ntawm Mercury vapors ib txwm ploj yuav ploj. Tsis tas li, kaw lub qhov rooj mus rau lwm chav.
2. Kev Sau Cov Tshuab Ntau Ntawm Mercury
Txhawm rau kom sau Mercury nws tsis tuaj yeem siv tus khaub rhuab, mop lossis nqus plua plav. Txwv tsis pub, tom qab tiv toj nrog Mercury, lawv yuav tsum tau muab pov tseg nrog cov mercury sau mercury.
Kev sib sau tsuas yog nyob rau hauv hnab looj tes thiab ua pa tiv thaiv khoom (tank-gauze daim ntaub qhwv).
Peb pom zoo siv:
Roj hmab pear;
Cov pa tassel nrog cov nplooj ntawv tuab lossis duab los qhia;
Scotch daim kab xev lossis ntaub nplaum ci;
Daim txhuam cev.
Yog li, muab tso rau cov ntaub qhwv cov ntaub qhwv thiab cov hnab looj tes roj hmab. Nws yog ib qho tsim nyog yuav tsum tau sau Mercury Balls rau tag nrho thaj chaw ntawm chav tsev. Nws yog qhov zoo dua los siv cov txhuam txhuam ntub rau qhov no, txhuam. Cov khoom loj raug muab tshem tawm ntawm daim ntawv thiab hliv rau hauv lub thawv nrog kev daws teeb meem nrog cov pipette lossis scotch (txawm tias tus npliag ntawm cov qhob cij) thiab nco ntsoov muab tso rau hauv tib lub hwj.
3. Kev kho tshuaj lom neeg tshuaj lom
Lub ntsiab lus ntawm hom no yog qhov seem ntawm Mercury muaj kuab, thiab hauv cov tshuaj tiv thaiv cov tshuaj, uas yog tom qab tau yooj yim yaug.
Noj 2 gram ntawm manganese, yaj nws hauv 1 liter dej. Nws hloov tawm ib qho 0.2% kev daws teeb meem ntawm poov tshuaj permanganate. Koj tseem tuaj yeem siv cov tshuaj dawb lossis lwm tus neeg sawv cev hauv chlorine.
Tom ntej, txheej txheem qhov chaw (pem teb, cov chaw nyob nruab nrab ntawm cov laug cam, phab ntsa), qhov chaw teeb (clf) lossis lwm yam khoom siv muaj Mercury poob. Tom qab koj yuav tsum ua cov chaw no nrog cov tshuaj soap-sida (4% ntawm cov xab npum yaj ntawm cov dej qab zib). Thiab yog li, koj yuav tsum rov ua dua 3-4 zaug hauv ob peb hnub.
Tsis txhob hnov qab tias txhua lub sijhawm thaum tu chav tsev yuav tsum muaj qhov cua. Nrog qhov chaw nqus tau tas mus li, kev ua kom muaj zog, kev pom ntawm Mercury vapor yuav rov qab mus rau qhov qub tsis pub dhau 1-3 lub hlis. Tab sis, raws li txoj cai, yog tias txhua yam ua tiav thiab sau Mercury txaus, muaj kev hem thawj loj rau lub neej no tsis tau dais. Nco ntsoov, lub txhab nyiaj nrog cov mercury sau nyob rau hauv tsis muaj ntaub ntawv nyob rau hauv lub pob lossis phem dua, ntxuav tawm mus rau hauv lub lim dej, ua rau tag nrho cov tsev nyob. Koj yuav tsum hu ua Ministry of Spurtressure Spartress, thiab 112, kom koj qhia seb koj yuav ua li cas thiaj ua tau kom raug thiab qhov twg tus ntaus nqi kom raug rau Mercury.
