Te Pūhaumāota Rānamu (Lacl3)
Whakaahuatanga o te hua
He ngāwari te wairewa o te konutai heptahydrate o te rānamu ki te wai, ā, he tere te tukanga waimeha, ā, ka haere tahi me ngā panonitanga o te pūngao. Ko tēnei waimehatanga tino pai te pūtake mō ōna tono i roto i ngā mara maha.
I roto i te umanga matū, ka whakamahia te konupūmā lanthanum hei whakakorikori mō ngā tauhohenga matū maha.
I roto i te umanga hiko, ka whakamahia te konupūmā lanthanum hei rauemi mata parakore mō te hanga i ngā wāhanga hiko pēnei i ngā pūnga me ngā haurua-ā-ira. I roto i te umanga matū hinu, ka taea te whakamahi i ngā whakakorikori e whakamahi ana i te konupūmā lanthanum i roto i te tukanga whakamahine o te hinu hei āwhina i te tango i ngā poke me te whakapai ake i te kounga o ngā hua hinu.
I roto i te umanga maimoatanga wai, ka whakamahia te konupūmā lanthanum hei tango i ngā poke pēnei i ngā katote konganuku taumaha, ngā phosphates, me ngā fluorides i roto i te wai para mā roto i ngā tikanga precipitation, adsorption rānei. Ka taea hoki e te konupūmā lanthanum te tauhohe ki ētahi katote konganuku taumaha. Hei tauira, ka taea e ia te hanga i ngā matūriki me ngā katote mata, ngā katote mercury, me ētahi atu. Mā te whakarerekē i te pH o te wai, ka tauhohe te LaCl2.3ā, ka taea te whakatairanga i ngā katote konganuku taumaha, ka huri i ngā katote konganuku taumaha wairewa hei waikura konganuku kore wairewa, hei matū whakarewa rānei - he lanthanum, ka tangohia mā te tātari, mā te whakatōpuku rānei, ka whakaiti i te kukū o ngā katote konganuku taumaha i roto i te wai, ā, ka tutuki i te wai ngā paerewa kounga e tika ana. I roto i te wai, ko te phosphate tētahi o ngā mea matua e hua ai te eutrophication. LaCl3Ka taea te tauhohe ki ngā katote phosphate hei hanga i te phosphate lanthanum kore-rewa, ā, ka whakahaere i te tipu o te rimurimu me ētahi atu rauropi wai, ka ārai hoki i te whakamomona wai.
Neke atu i te tekau tau a te kamupene WONAIXI e hanga ana i te konupūmā lanthanum. Kei te whakapai tonu mātou i te tukanga whakaputa, kia taea ai e mātou te tuku atu i te hua kounga teitei. I tēnei wā, ko te kaha whakaputa ā-tau a WNX he 1,500 tana o te konupūmā lanthanum. Ka hokona ā mātou hua konupūmā lanthanum ki te kāinga me tāwāhi.
