EDTA 4NA.4H2O CAS 13254-36-4
Hiki ke hoʻoheheʻe ʻia ʻo EDTA 4NA.4H2O i ka wai a hiki ke hoʻopili ʻia me nā ʻano ion metala like ʻole. I nā ʻano pH like ʻole a me nā ʻano like ʻole o ka wai paʻakikī i loaʻa ka calcium, hiki iā ia ke paʻakikī, a ʻo ka pH≥8 ka hopena kiʻekiʻe loa. Me ka lakio molar 1:1 o nā ion calcium, he kūpaʻa maikaʻi kona i ka wai, a ʻaʻole e palaho i ka wai wela loa, a he mea palupalu wai paʻakikī maikaʻi loa ia.

Hoʻohana ʻia ʻo EDTA 4NA.4H2O ma ke ʻano he mea palupalu wai, mea hoʻouluulu rubber synthetic, mea hoʻopau polymerization fiber acrylic, nā mea hoʻohui paʻi a me ke kala ʻana, nā mea hoʻohui detergent, a me ka hopena hoʻopaʻa bleaching no ka hana holoi ʻana i nā mea ʻike kala. I ka nānā ʻana i nā kemika, hoʻohana ʻia nō hoʻi no ka titration, hiki ke titration pololei i nā ʻano ion metala like ʻole.
