EDTA 4NA.4H2O CAS 13254-36-4
Ko te EDTA 4NA.4H2O he wairewa ki te wai, ka taea te chelated ki nga momo katote whakarewa. I roto i te whānuitanga o te awhe pH me te maha o nga kukū o te wai mārō konupūmā-kei roto i te kaha ki te matatini, me te pH≥8 i te tino whai huatanga. Ki te 1:1 molar ōwehenga o konupūmā katote, he pai te pūmautanga waiariki i roto i te wai, a ka kore e pirau ahakoa i roto i te wai wera rawa, a he tino whai hua whakamaroke wai mārō.

Ko te EDTA 4NA.4H2O ka whakamahia hei whakamahana wai, hei whakakorikori rapa waihanga, hei whakamutu i te polymerization muka kiriaku, hei taapiri tae me te tae, hei taapiri horoi, me te otinga whakatika whakangao mo te tukatuka horoi horoi. I roto i te tātari matū kei te whakamahia hoki mo te titration, ka taea e tika te titration te momo o te katote whakarewa.
