ʻO EDTA-4Na, i kapa ʻia ʻo tetrasodium EDTA a i ʻole EDTA-Na4, he mea hoʻohana chelating i hoʻohana ʻia i nā ʻoihana like ʻole.ʻO kāna mau mea kemika kū hoʻokahi e lilo ia i mea koʻikoʻi no ka nui o nā noi.

ʻO EDTA-4Na he pauka keʻokeʻo keʻokeʻo me kahi ʻano mole o C10H12N2Na4O8 a me ke kaumaha molekala o 380.17 g/mol.Loaʻa ka solubility kiʻekiʻe i ka wai, no laila hiki ke hoʻohana maʻalahi i nā ʻano wai wai.Paʻa ka kemika ma lalo o nā kūlana maʻamau a he lōʻihi kona ola e hōʻoia i ka hana paʻa lōʻihi.

ʻO nā waiwai chelating maikaʻi o EDTA-4Na he kuleana koʻikoʻi i nā kaʻina hana ʻoihana.Hiki iā ia ke hana i nā paʻa paʻa me nā ion metala, a me ka chelate maikaʻi i nā ion metala e like me ka calcium, magnesium, iron, a me ke keleawe.No laila, hiki i kēia waiwai ke hoʻoneʻe i nā mea hoʻohaumia metala i makemake ʻole ʻia a pale i kā lākou hopena ʻino i nā noi like ʻole.

Hoʻohana nui ʻia ʻo EDTA-4Na i nā ʻoihana ʻoihana, e komo pū ana akā ʻaʻole i kaupalena ʻia i ka mālama wai, mahiʻai, lāʻau lapaʻau, meaʻai a me nā ʻoihana hoʻonaninani.ʻO kona hiki ke hoʻokahe i nā ion metala he mea nui ia i ka mālama ʻana i ka wai e kōkua i ka pale ʻana i ka hoʻokumu ʻana o ka unahi a kōkua i ka wehe ʻana i nā ion metala kaumaha mai ka wai ʻino.Eia kekahi, hana ia ma ke ʻano he stabilizer a me ka preservative i nā huahana like ʻole, e hōʻoiaʻiʻo ana i ka kiʻekiʻe kiʻekiʻe a me ke ola papa.

Welina mai i kā mākou huahana hoʻolauna o EDTA-4Na (CAS: 64-02-8).Ua hauʻoli mākou i ka hoʻolauna ʻana i kēia mea kemika nui e hoʻokō i nā pono ʻoihana like ʻole.Ma kēia ʻatikala, e hāʻawi mākou iā ʻoe i kahi ʻike o ka huahana, kāna mau noi, a me nā pōmaikaʻi e hiki ke lawe mai i kāu ʻoihana.Ke kono nei mākou iā ʻoe e ʻimi i kā mākou hāʻina a paipai iā ʻoe e hoʻokaʻaʻike mai iā mākou me nā nīnau.

ʻO EDTA-4Na (CAS: 64-02-8) he mea kemika koʻikoʻi me nā noi like ʻole i nā ʻoihana like ʻole.ʻO kāna mau waiwai chelating a me ka paʻa maikaʻi loa e lilo ia i mea hilinaʻi a kūpono hoʻi no nā kaʻina hana ʻenehana.Ma keʻano he mea hoʻolakoʻoihana o nā kemika kiʻekiʻe, ua paʻa mākou i ka hāʻawiʻana i nā huahana a me nā lawelawe maikaʻi loa e hoʻokō i nā pono o kā mākou mea kūʻai.Inā he nīnau kāu a makemake ʻoe i ka ʻike hou aku, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
