EDTA 4NA.4H2O CAS 13254-36-4
Hiki ke hoʻoheheʻe ʻia ʻo EDTA 4NA.4H2O i ka wai a hiki ke hoʻokaʻawale ʻia me nā ʻiona metala like ʻole. I loko o nā ʻano pH like ʻole a me nā ʻano ʻokoʻa o ka wai paʻakikī i loko o ka calcium ka hiki ke paʻakikī, a me ka pH≥8 i ka hopena kiʻekiʻe loa. Me ka 1:1 molar ratio o ka calcium ions, he maikai ka wela i ka wai, aole e decompose i loko o ka wai wela loa, a he mea hooluolu wai paakiki loa.

Hoʻohana ʻia ʻo EDTA 4NA.4H2O ma ke ʻano he mea hoʻomaʻemaʻe wai, synthetic rubber catalyst, acrylic fiber polymerization terminator, paʻi ʻana a me nā mea hoʻohui wai, nā mea hoʻohui hoʻomaʻemaʻe, a me ka bleaching fixing solution no ka hoʻomaʻemaʻe ʻana i nā mea ʻili kala. I ka ho'āʻo kemika ua hoʻohana 'ia no ka titration, hiki pololei titration i nāʻano metala ion.
