Āhuatanga:
Ko te EDTA 4NA he paura tioata ma e 4 te wai karaihe, he ngawari te whakarewa i te wai, he kawakore te wairewa wai, he iti te wairewa i roto i nga whakarewa pararopi penei i te waiwaro, ka ngaro tetahi waahanga, te katoa ranei o te wai karaihe i te teitei teitei.
Nga tono:
Ko te EDTA 4NA he katote katote e whakamahia nuitia ana.
1. Ka taea te whakamahi i roto i te ahumahi kakano mo te tae, te whakarei ake i te tae, te whakapai ake i te tae me te kanapa o nga papanga tae.
2. Ka whakamahia hei taapiri, hei whakakorikori, hei katote whakarewa me te kaiwhakaoho i roto i te umanga rapa butadiene.
3. Ka taea te whakamahi i roto i te ahumahi kiriaku maroke hei whakakore i te pokanoa whakarewa.
4. Ka taea hoki e EDTA 4NA te whakamahi i roto i te horoi horoi wai hei whakapai ake i te kounga horoi me te painga horoi.
5. Ka whakamahia hei whakamahana wai, hei horoi i te wai, whakamahia mo te maimoatanga o te kounga o te wai.
6. Ka whakamahia hei whakakorikori rapa waihanga, te kaitapa polymerization kiriaku, he awhina mo te ta me te tae, me era atu.
7. Ka whakamahia hoki mo te titration i roto i te wetewete matū, a ka taea te titrate tika i nga momo katote whakarewa.
8. I tua atu i nga whakamahinga o runga ake nei, ka taea hoki te whakamahi i te EDTA 4NA i roto i te rongoa, te matū o ia ra, te hanga pepa me etahi atu ahumahi.
