Ngā Āhuatanga:
Ko te EDTA 4NA he paura tioata ma, kei roto ko te 4 tioata wai, he ngāwari te wairewa ki te wai, he kawakore te wairewa, he paku wairewa ki ngā whakarewa waro pēnei i te etanoru, ā, ka ngaro pea tetahi wāhanga, te katoa rānei o te wai tioata i te pāmahana teitei.
Ngā tono:
He matū chelator katote whakarewa e whakamahia whānuitia ana te EDTA 4NA.
1. Ka taea te whakamahi i roto i te umanga kakahu mō te tae, te whakarei ake i te tae, te whakapai ake i te tae me te kanapa o ngā papanga kua taehia.
2. Whakamahia hei tāpiri, hei whakahohe, hei ārai i te katote whakarewa me te whakahohe i roto i te umanga rapa butadiene.
3. Ka taea te whakamahi i roto i te umanga kiriaku maroke hei whakakore i te pokanoa whakarewa.
4. Ka taea hoki te whakamahi i te EDTA 4NA i roto i te hopi horoi wai hei whakapai ake i te kounga horoi me te pānga horoi.
5. Whakamahia hei whakangawari wai, hei horoi wai, hei rongoā kounga wai.
6. Whakamahia hei whakakorikori rapa hangai, hei whakamutu i te whakakotahitanga kiriaku, hei āwhina tā me te tae, me ētahi atu.
7. E whakamahia ana hoki mō te ine ira i roto i te tātari matū, ā, ka taea te ine tika i ngā momo katote konganuku.
8. Haunga ngā whakamahinga o runga ake nei, ka taea hoki te whakamahi i te EDTA 4NA i roto i ngā mahi rongoā, ngā mahi matū o ia rā, te hanga pepa me ētahi atu ahumahi.
