Tlhahlobo ea Lintho tse nang le Mahlaseli a Motlakase le Lintho tse Chefo Li-Cenospheres tsa Molora o Fofang: Pono ea Polokeho le Tikoloho

1. Mehloli ea Radioactivity le Li-Elements tse Chefo ho Cenospheres

Likarolo tsa Mahlaseli

Kaha di-cenospheres di simoloha ho tjheseng ha mashala, di futsa bongata ba dintho tse nang le mahlasedi a kotsi a tlhaho (NORMs) tse teng ka hara mashala. Dikarolo tsa mantlha tsa mahlasedi a kotsi ke:

• Uranium (U)

• Radium (Ra)

• Thorium (Th)

• Potasiamo-40 (K-40)

Dielemente tsena di fumanwa mashaleng ka lebaka la mekgwa ya ho thehwa ha jeoloji. Ha mashala a tjheswa, boholo ba dintho tse phelang di a jewa, empa diminerale tse sa pheleng—ho kenyeletswa le di-isotope tse nang le mahlasedi a kotsi—di bokellane moloreng o hlahang. Di-cenospheres, e leng karolo e nyane ya molora o fofang, di ka nna tsa ba le maemo a hodimo hanyane a dielemente tsena ha di bapiswa le molora o fofang ka bongata ka lebaka la sebopeho sa tsona se nang le masoba le thepa ya tsona ya bokahodimo.

Tšepe e Boima e Chefo

Ntle le radioactivity, li-cenospheres li ka 'na tsa ba le palo e nyenyane ea litšepe tse chefo tse boima, ho kenyeletsoa:

• Mercury (Hg)

• Arsenic (As)

• Chromium (Cr)

• Lead (Pb)

• Cadmium (Cd)

Dielemente tsena di teng ka tlhaho mashaleng mme di ka bokellana moloreng wa dintsintsi nakong ya ho tjha. Leha ho le jwalo, mahlale a sejwalejwale a taolo ya tshilafatso (jwalo ka di-precipitator tsa motlakase le di-scrubbers) a fokotsa haholo ho ntshwa ha tsona tikolohong.

2. Mekhoa ea Teko le Maemo a Polokeho

Teko ea Mahlaseli a Motlakase

Ho netefatsa polokeho, li-cenospheres li lekoa ka ho sebelisa li-spectrometry tsa gamma (li-HPGe detectors), e lekanyang ka nepo mahloriso a li-isotope tse nang le mahlaseli a kotsi. Liteko li etsoa lilaboratoring tse amohetsoeng ho latela maemo a machaba a kang:

• Maemo a Polokeho a IAEA

• Tataiso ea US EPA

• Tataiso ea Euratom ea Khomishene ea Europe

• GB 6566-2010 (Moeli oa Mahlaseli a Thepa ea Kaho oa Chaena)

Tlhahlobo ea Lintho tse Chefo

Dikahare tsa heavy metal di sekasekwa ho sebediswa:

• Spectrometry ea 'Mele oa Plasma o Kopantsoeng ka Inductively (ICP-MS)

• Spectroscopy ea ho Monya Atomic (AAS)

• Phatsimo ea X-ray (XRF)

Meeli ea taolo bakeng sa likarolo tse chefo e behiloe ke:

• Mokhoa oa ho Leaching oa Tšobotsi ea Chefo ea US EPA (TCLP)

• Molao oa REACH oa EU

• GB 5085.3-2007 ea Chaena (Tekanyetso ea Boitsebiso ba Litšila Tse Kotsi)

3. Tlhahlobo ea Papiso le Meeli ea Taolo

Maemo a Radioactivity ho Cenospheres khahlanong le Maemo a Polokeho

Liteko tse pharaletseng li tiisa hore maemo a radioactivity a cenosphere a ka tlase haholo ho meeli ea taolo. 

Matšoafo a Chefo a Tšepe Khahlanong le Meeli ea Polokeho

Ka ho tšoanang, tekanyo ea tšepe e boima li-cenospheres e ka tlase haholo ho maemo a kotsi.

Tekanyo ea litaba tsa likarolo tse ntšang mahlaseli a kotsi ka har'a lifaha tse phaphametseng e entsoe ke Chinese Academy of Metrology ho sebelisoa HPGe HPGe Y spectrometer.

4. Litlamorao tsa Tikoloho le Bophelo bo Botle

Melemo ea Tšebeliso ea Cenosphere Tikolohong

• Phokotso ea Litšila: Ho sebelisa li-cenospheres ho thibela molora o fofang ho kena libakeng tsa ho lahla lithōle.

• Karolo e ka Tlase ea Khabone: Ho nkela di-microsphere tsa maiketsetso sebaka ka di-cenosphere sebaka ho fokotsa tlhahiso e jang matla a mangata.

• Kaho e Tsitsitseng: Konkreite e bobebe ea cenosphere e fokotsa boima ba moaho le tšebeliso ea thepa.

Mehopolo ea Bophelo bo Botle le Polokeho

• Ha ho na Mahlaseli a Bohlokoa a Hlasetsang: Basebetsi ba sebetsanang le li-cenospheres ha ba tobane le kotsi e phahameng ea mahlaseli ho feta maemo a tlhaho a tlhaho.

• Chefo e sa Lutlang: Litšepe tse boima li koaletsoe ka lik'hemik'hale ka har'a matrix e kang khalase ea li-cenospheres, e leng se thibelang ho lokolloa ha tikoloho.

• Mekhoa ea ho Tšoara ka Mokhoa o Sireletsehileng: PPE ea motheo (liatlana, limaske) e lekane bakeng sa tšebeliso ea indasteri.

5. Mekhoa e Metle bakeng sa Likopo tse Sireletsehileng tsa Indasteri

Ho eketsa polokeho le botsitso, liindasteri tse sebelisang li-cenospheres li lokela ho:

✔ Mohloli o tsoang ho Barekisi ba Botumo (ka litlaleho tsa liteko tsa laboratori)
✔ Boloka ka har'a lijana tse koetsoeng (thibela ho hasana ha lerōle)
✔ Latela Melao ea Sebaka (litataiso tsa ho lahla litšila)
✔ Hlokomela ho pepesehela Sebaka sa Mosebetsi (litlhahlobo tsa polokeho tsa kamehla)

Qetello: Li-cenospheres ke Khetho e Sireletsehileng, e Tšoarellang

Tlhahlobo ea saense e tiisa hore li-cenospheres tsa molora o fofang lia ema ha ho kotsi e kholo ea mahlaseli a kotsi kapa chefo ha di sebediswa ditirisong tsa diindasteri. Melemo ya tsona tikolohong—jwalo ka phokotso ya matlakala le ho fokotsa mosi o tswang khaboneng—di etsa hore e be mokhoa o mong o sireletsang tikoloho ho li-filler tsa setso le li-additives.

Ka ho khomarela maemo a taolo le mekhoa e metle, liindasteri li ka sebelisa li-cenospheres ka kholiseho ho:

• Konkreite e bobebe

• Ho kenya mocheso

• Lihlopha tsa Likoloi

• Ho Cheka Oli le Khase

• Liaparo tse sa Cheseng

Ha lefats'e le ntse le fetohela ho moruo o chitja melao-motheo, li-cenospheres li emela tharollo ea bohle ba hlōlang—ho fetola dihlahiswa tse setseng tsa indasteri hore e be thepa ya bohlokwa, e bolokehileng, le e tshwarellang.
