Oxalic Acid

fa'amatalaga puupuu:

O se ituaiga o meaola faʻalaʻau, o se metabolic oloa o meaola, binary acid, tufatufaina lautele i laau toto, manu ma fungi, ma i meaola ola eseese taʻalo galuega eseese.Ua maua o le oxalic acid e mauoa i le silia ma le 100 ituaiga o la'au, aemaise o mea'ai, amaranth, beet, purslane, talo, pateta suamalie ma le rhubarb.Talu ai ona o le oxalic acid e mafai ona faʻaitiitia ai le bioavailability o elemene minerale, e manatu o se tagata tetee mo le faʻaogaina ma le faʻaogaina o elemene minerale.O lona anhydride o le carbon sesquioxide.

Fa'aogaina o Mea

Fa'aopoopo vali

I le lolomiina ma le valiina o pisinisi, e mafai ona suitulaga ai le acetic acid e fai ai lanu muamua.Fa'aaogaina e fai ma vali lanu ma pa'u mo vali lanu.E mafai ona tu'ufa'atasia ma nisi vaila'au e fai ai ni vali, ma e mafai fo'i ona fa'aoga e fai ma fa'amautu mo vali, ma fa'alautele ai le ola o vali.

Fa'amama

O le faʻaaogaina o le zeolite e pei o le faʻatumu i totonu o le pisinisi pepa e mafai ona faʻaleleia le faʻatinoga ma le lelei o pepa, ina ia faʻateleina lona porosity, faʻaleleia le faʻaogaina o le vai, sili atu ona faigofie ona tipi, faʻaleleia le tusitusi, ma o loʻo i ai ni faʻalavelave afi.

Alamanuia palasitika

Alamanuia palasitika mo le gaosiga o polyvinyl chloride, palasitika amino, urea formaldehyde palasitika, vali meataalo ma isi.

Alamanuia photovoltaic

Oxalic acid o loʻo faʻaaogaina foi i le alamanuia photovoltaic.Oxalic acid e mafai ona fa'aoga e fai ai fa'ama'i fa'ama'i silicon mo panels sola, e fesoasoani i le fa'aitiitia o fa'aletonu i luga ole la'ei o fa'ama'i sikoni.

Fufulu oneone

Oxalic acid fa'atasi ma le hydrochloric acid ma le hydrofluoric acid e mafai ona galue i luga o le fufuluina o le suka o le oneone quartz.

Fa'atupu fa'atupu

I le avea ai o se faʻamalosi mo le faʻapipiʻiina o le resini phenolic, o le tali faʻamaʻi e agamalu, o le faagasologa e matua mautu, ma o le umi e sili ona umi.Ole vaifofo ole acetone oxalate e mafai ona fa'afefeteina le fa'amalologa ole epoxy resin ma fa'apu'upu'u le taimi fa'amalolo.E faʻaaogaina foʻi e fai ma faʻatonuga o le pH mo le faʻapipiʻiina o le urea-formaldehyde resin ma le melamine formaldehyde resin.E mafai foi ona faaopoopo i le vai-soluble polyvinyl alcohol adhesive e faʻaleleia ai le saoasaoa faʻamago ma le malosi faʻapipiʻi.E mafai foi ona faʻaaogaina e fai ma sui faʻamalolo o le urea-formaldehyde resin ma le uʻamea chelating agent.E mafai ona faʻaaogaina e fai ma faʻavavevave e saunia ai le faʻamaʻi masoa ma le KMnO4 oxidizing agent e faʻavave ai le faʻamaʻiina ma faʻapuʻupuʻu taimi tali.
