Na 1 PM na Ọgọst 24,2023, gọọmentị Japan leghaara obi abụọ siri ike na mmegide nke mba ụwa wee manye n'otu akụkụ manye mwepụ nke mmiri emetọghị na mberede nuklia Fukushima.Ihe Japan mere bụ ịnyefe ihe ize ndụ n'ụwa, gbasaa ihe mgbu na ọgbọ nke ụmụ mmadụ n'ọdịnihu, ghọọ mmebi nke gburugburu ebe obibi na onye na-emetọ mmiri zuru ụwa ọnụ, mebie ikike ahụike, mmepe na gburugburu ebe obibi nke mba niile, na imebi ya. ọrụ omume na iwu mba ụwa.Mba mba ụwa ga-akatọ ahịrị ahịrị Japan nke mmiri mmetọ mmiri nuklia ruo ogologo oge.Gọọmentị China na-ebutekarị ndị mmadụ ụzọ ma na-eme ihe niile dị mkpa iji chekwaa nchekwa nri na ahụike ndị China.
Mgbe mwepu nke mmiri mkpofu sitere na Japan, ọnụọgụ tritium dị na gburugburu mmiri mmiri nwere ike ịba ụba, nke ga-enwe mmetụta na gburugburu ebe obibi mmiri.Dị ka obodo bụ isi n'oké osimiri, nleba anya China na tritium mmiri dị n'ụsọ oké osimiri nwere ike ịghọta mgbanwe na gburugburu mmiri mmiri n'oge ma duga nchekwa nke gburugburu ebe obibi mmiri.
Dịka obodo dị mkpa dị nso na Japan, ileba anya n'ihe gbasara nri mmiri dịkwa oke mkpa iji chebe ahụike mmadụ na gburugburu ebe obibi.
Nke mbụ, ihe oriri na-edozi ahụ nwere uru nri dị elu yana ọchịchọ ahịa.Otú ọ dị, n'ihi mmetọ mmiri na ọnụnọ nke ihe ndị na-emepụta redioaktivu, ọkwa redioaktivu nke nri mmiri nwere ike karịa ọkọlọtọ, na-etinye ihe ize ndụ nye ahụike mmadụ.Ya mere, ileba anya na ọkwa redioactivity nke nri mmiri ndị China nwere ike hụ na nchekwa nri nke ndị na-azụ ahịa.
Nke abuo, oké osimiri bụ akụkụ dị mkpa nke gburugburu ebe obibi gburugburu ụwa.Enweghị ike ileghara mmerụ ahụ nke ihe redioaktivu na gburugburu gburugburu ebe obibi mmiri anya.Nyochaa ọkwa redioactivity nke nri mmiri ndị China nwere ike ọ bụghị naanị ichebe ahụ ike nke ahụ mmadụ, kamakwa inye aka ịghọta ọnọdụ mmetọ nke gburugburu ebe obibi mmiri, ma nye ntọala sayensị maka nchekwa gburugburu ebe obibi.
Na nkenke, mkpa ọ dị nleba anya na redioactivity nke ihe oriri mmiri na China mgbe mwepu nke mmiri mkpofu na Japan pụtara n'onwe ya.Anyị kwesịrị ịnakwere usoro nleba anya nke sayensị na nke dị irè iji wusie mma na nchekwa nchekwa nke nri mmiri iji hụ na nchekwa na ahụike ndụ ndị mmadụ.
Ụlọ ọrụ anyị enyela gị usoro nlekota oru nlekota oru maka mmiri mmiri na ihe oriri na-edozi ahụ, gụnyere nlele, nkwadebe nlele na usoro nlekota nke mmiri mmiri na ihe oriri na-edozi ahụ, ma nwee ngwá ọrụ akwadoro kwekọrọ.
Nnwale usoro maka tritium n'ime mmiri:
1. Nlele ubi;
2. Distillation na ụzọ ndị ọzọ nke iwepụ ion;
3. Dị ka HJ1126-2020 si kwuo "Usoro nyocha nke tritium na mmiri", na-eji usoro electrolytic, na ngwá ọrụ ntinye uche nke tritium electrolytic;
4. A na-agbakwunye mmiri mmiri sintilation wee tụọ ya site na iji mpempe scintillation mmiri.
Site na usoro a, enwere ike ikpebi ma nyochaa tritium radioactivity na mmiri mmiri.
Usoro nchọpụta maka tritium na carbon 14 n'ime nri mmiri:
1. Ihe atụ;
2. Bee / bee iberibe;
3. Lyophiliser lyophilization (mmiri lyophilized na-ejikọta ọnụ maka nchọpụta, ga-enwekwa tritium!);
4. Igwe na-egweri igwe;
5. Iji organic tritium carbon sample ngwaọrụ wepụ redioaktivu tritium na carbon-14;
6. A na-ewepụta Triitium n'ụdị mmiri catalytic;
7. A na-ewepụta carbon n'ụdị catalytic nke carbon dioxide ma tinye ya na sodium hydroxide;
8. A na-agbakwunye ihe redioaktivu ewepụtara na mmiri scintillation wee tụọ ya site na iji mpempe akwụkwọ scintillation mmiri.
Mgbe usoro a gasịrị, enwere ike ikpebi ma nyochaa tritium na carbon radioactivity na nri mmiri.
