He aha ka ʻokoʻa ma waena o Edta a me Sodium Citrate?

ʻO ka ʻokoʻa koʻikoʻi ma waena o EDTA a me ka sodium citrate ʻo ia ka pono o ka EDTA no nā hoʻokolohua hematologic no ka mea e mālama ʻo ia i nā keneta koko ʻoi aku ka maikaʻi ma mua o nā mea like ʻē aʻe, akā pono ka sodium citrate ma ke ʻano he mea hoʻāʻo coagulation no ka mea ʻoi aku ka paʻa o nā mea V a me VIII i kēia mea.

He aha ka EDTA (Ethylenediaminetetraacetic Acid)?

ʻO ka EDTA a i ʻole ka ʻakika ethylenediaminetetraacetic he aminopolycarboxylic acid nona ke ʻano kemika [CH2N(CH2CO2H)2]2.ʻIke ʻia ʻo ia ma ke ʻano he paʻa keʻokeʻo hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana nui ʻia i ka hoʻopaʻa ʻana i nā ion hao a me ka calcium.Hiki i kēia mea ke hoʻopaʻa me kēlā mau ion ma nā wahi ʻeono, e alakaʻi ana iā ia e ʻike ʻia ʻo ia ka nui-toothed (hexadentate) chelating agent.Hiki ke loaʻa nā ʻano like ʻole o EDTA, ʻoi loa ka disodium EDTA.

Ma ka ʻoihana, pono ʻo EDTA ma ke ʻano he mea hoʻokaʻawale no ka hoʻopaʻa ʻana i nā ion metala ma nā haʻina wai.Eia kekahi, hiki iā ia ke pale i nā haumia ion metala mai ka hoʻololi ʻana i nā kala o nā kala i loko o ka ʻoihana textile.Eia kekahi, pono ia i ka hoʻokaʻawale ʻana i nā metala lanthanide e ka chromatography hoʻololi ion.Ma ke kahua o ka lāʻau lapaʻau, hiki ke hoʻohana ʻia ʻo EDTA no ka mālama ʻana i ka mercury a me ke alakaʻi make ma muli o kona hiki ke hoʻopaʻa i nā ion metala a kōkua i ka hoʻokaʻawale ʻana iā lākou.Pēlā nō, he mea nui ia i ka nānā ʻana i ke koko.Hiki ke hoʻohana ʻia ʻo EDTA ma ke ʻano he mea hoʻohui i nā huahana mālama pilikino e like me ka shampoo, nā mea hoʻomaʻemaʻe, a me nā mea ʻē aʻe, ma ke ʻano he sequestering agent.

He aha ka Sodium Citrate?

ʻO ka sodium citrate kahi pūhui anorganic i loaʻa nā cation sodium a me nā anion citrate i nā lakio like ʻole.ʻEkolu ʻano nui o ka sodium citrate mole: monosodium citrate, disodium citrate, a me trisodium citrate mole.ʻO ka hui pū ʻana, ʻike ʻia kēia mau paʻakai ʻekolu e ka helu E 331. Eia naʻe, ʻo ke ʻano maʻamau ka paʻakai trisodium citrate.

Loaʻa i ka Trisodium citrate ke ʻano kemika Na3C6H5O7.ʻO ka hapa nui o ka manawa, kapa ʻia kēia pūhui i ka sodium citrate no ka mea ʻo ia ke ʻano nui o ka paʻakai sodium citrate.He ʻono koʻikoʻi ko kēia ʻano mea like me ka paʻakai.Eia kekahi, he mea maʻalahi kēia pūhui, a hiki iā mākou ke hoʻohana iā ia e hana i nā hoʻonā buffer me ka waikawa citric.ʻIke ʻia kēia mea ma ke ʻano he pauka crystalline keʻokeʻo.ʻO ka mea nui, hoʻohana ʻia ka sodium citrate i ka ʻoihana meaʻai ma ke ʻano he mea hoʻohui meaʻai, ma ke ʻano he mea ʻono a i ʻole he preservative.

He aha ka ʻokoʻa ma waena o EDTA a me Sodium Citrate?

ʻO ka EDTA a i ʻole ka ʻakika ethylenediaminetetraacetic he aminopolycarboxylic acid nona ke ʻano kemika [CH2N(CH2CO2H)2]2.ʻO ka sodium citrate kahi pūhui inorganic i loaʻa nā cation sodium a me nā anion citrate i nā ratio like ʻole.ʻO ka ʻokoʻa koʻikoʻi ma waena o EDTA a me ka sodium citrate ʻo ia ka pono o ka EDTA no ka hoʻāʻo hematologic no ka mea ʻoi aku ka maikaʻi o ka mālama ʻana i nā keneta koko ma mua o nā mea like ʻē aʻe, akā ʻo ka sodium citrate ka mea pono ma ke ʻano he mea hoʻāʻo coagulation no ka mea ʻoi aku ka paʻa o nā mea V a me VIII i kēia mea.
