Te Strontium Nitrate mō te Whakamahinga Ahumahi: He Aratohu Hangarau mō ngā Kaihoko o te Ao
—— Te Kōwhiringa Māka, Te Whakataurite Tono me Ngā Tikanga Pai mō te Whakatutukitanga
Te pākawa waro o te strontium [Sr(NO₃)₂] he nitaraiti whenua kawakore nui te uara e whakamahia whānuitia ana i roto i ngā hangarau mura, te karāhe whatu, ngā uku hiko, me ngā matū tātari. Nā tōna tae mura whero ahurei me ōna āhuatanga waikura, kāore e taea te whakakapi i roto i ngā tukanga hangahanga mahi teitei.
He maha ngā kaihoko o te ao e aro ana ki te ihirangi Sr me te utu kotahi ina rapu ana, engari kāore e aro ki ngā poke nui: Ba, Ca, Fe, me Cl⁻. Mā ēnei poke ka whakatau tika te mahi a te hua whakamutunga, te ōritetanga o te tae, me te pumau o te tukanga.
Mā tēnei aratohu ka āwhina ngā kaihoko o te ao ki te mārama ki ngā paerewa tohu, te kōwhiringa motuhake ki ngā tono, me te tutuki i ngā ture mō ngā mekameka tuku o te ao.
1. Ngā Āhuatanga me te Whakarōpūtanga Paerewa
Ngā Āhuatanga Ā-tinana me te Matū
Paura tioata mā/kore tae
Ka wairewa ki te wai, he āhua waikura te wai
He matū whakahāora kaha (ka tukuna te O₂ i ngā pāmahana teitei)
Ka puta he mura whero kaha (he tae matua mō te mura ahi)
E wātea ana i te ahua tioata, paura rānei; ka taea te whakarite i te rahi o te matūriki
Pūnaha Taumata Ahumahi (Hototahi ki te Ao)

Kua whakahoutia te MSDS (e tutuki ana i ngā whakaritenga GHS, te haumaru kawe waka o te ao)
COA puranga me te whai i te katoa (whakamātautau + raraunga poke: Ba, Ca, Fe)
2. Ngā Mātāpono Taupānga me te Arorau Taurite Māka
Ngā Tikanga Mahi Matua
Ka tukuna te hāora e te pirau wera; ka tukuna e te Sr²⁺ te whānuitanga whero āhua
I roto i te karāhe: ka whakatika i te taupū whakaata me te mararatanga
I roto i ngā uku: e whakarato ana i te pūtake Sr whakahaeretia mō ngā āhuatanga hiko
Ngā Whakaritenga Motuhake mō te Taupānga
2.1 Ngā Pūrere Whakarewa me ngā Pūrere Tohu (Te Mākete Nui Rawa)
o Whakamahia i roto i ngā ahi whero, ngā tohu āwangawanga, ngā mura rererangi
o Tino Hiranga: Ba < 0.02% mō te mura whero parakore
Ka tukuna e te oBa te mārama matomato, ka puta he tae karaka; ka whakapai ake te taumata Ba-iti i te mātotoru o te tae me te whakaae a te kiritaki
2.1 Karāhe Whatu me ngā Uku Motuhake

3. Ngā Hapa me ngā Whakatikatika o te Hokonga Rauemi (Mō ngā Kaihoko o te Ao)
Hapa 1: Te aromatawai i te kounga mā te whakamātautau matua anake
Ko te parakore matua te whakaritenga iti rawa. Ko ngā poke Ba/Ca he nui ake te pānga ki te mahi i te rerekētanga parakore o te 1–2%. Whakatika: Whakatakotoria he rohe mārama mō Ba/Ca me tō rōpū R&D.
Hapa 2: Whakatairangahia te utu i te ōritetanga o te puranga
Ko te mana whakahaere o Ba e whakawhirinaki ana ki te hangarau purenga. Ko ngā puranga koretake ka hua ake he tae/mahi koretake. Whakatika: Kōwhiria he kaiwhakarato he tukanga pumau, kaua ko te utu iti rawa.
Hapa 3: Kaua e aro ki ngā raraunga taipitopito o te Ba/Ca mō te COA
He maha ngā COA ahumahi taketake kāore e whakarārangi motuhake i te Ba/Ca. Whakatika: Tauwhāitihia ngā tikanga whakamātautau me ngā rohenga i roto i tō whakaaetanga hangarau (tohutoro: GB/T 669-2013).
