Ndeupi Musiyano Uripo Pakati peEdta neSodium Citrate?

Musiyano mukuru uripo pakati peEDTA nesodium citrate ndewekuti EDTA inobatsira pakuongororwa kweropa nekuti inochengetedza masero eropa zviri nani kupfuura mamwe ma agents akafanana, nepo sodium citrate ichibatsira semushonga wekuyedza kuvharika kweropa sezvo zvinhu V neVIII zvakagadzikana muchinhu ichi.

Chii chinonzi EDTA (Ethylenediaminetetraacetic Acid)?

EDTA kana ethylenediaminetetraacetic acid iaminopolycarboxylic acid ine fomura yemakemikari [CH2N(CH2CO2H)2]2. Inotaridzika sechinhu chakasimba chichena, chinonyungudika mumvura chinoshandiswa zvakanyanya mukubatanidza kune iron necalcium ions. Chinhu ichi chinogona kubatana nemaion iwayo pamapoinzi matanhatu, izvo zvinoita kuti chizivikanwe semushonga wemazino ane saizi (hexadentate). Panogona kuva nemhando dzakasiyana dzeEDTA, dzinowanzo kuve nedisodium EDTA.

Mumaindasitiri, EDTA inobatsira semushonga wekusunga maion esimbi mumvura. Uyezve, inogona kudzivirira tsvina yesimbi kubva kumaion esimbi kuti isashandure mavara emadhayi muindasitiri yemachira. Pamusoro pezvo, inobatsira mukuparadzanisa simbi dzelanthanide ne ion-exchange chromatography. Mukurapa, EDTA inogona kushandiswa kurapa chepfu yemercury ne lead nekuda kwekugona kwayo kusunga maion esimbi nekubatsira mukuzviparadzanisa. Saizvozvowo, inokosha zvakanyanya mukuongorora ropa. EDTA inogona zvakare kushandiswa sechinhu chinoshandiswa muzvigadzirwa zvekuchengetedza muviri zvakaita se shampoo, cleaners, nezvimwewo, semushonga wekusunga maion.

Chii chinonzi Sodium Citrate?

Sodium citrate chinhu chisina kugadzirwa chine ma sodium cations uye ma citrate anions muzvikamu zvakasiyana. Kune mhando nhatu huru dzema sodium citrate molecules: monosodium citrate, disodium citrate, uye trisodium citrate molecule. Pamwe chete, munyu uyu mitatu unozivikanwa nenhamba E 331. Zvisinei, chimiro chakajairika i trisodium citrate salt.

Trisodium citrate ine fomura yemakemikari Na3C6H5O7. Kazhinji, chinhu ichi chinowanzonzi sodium citrate nekuti ndiyo mhando yakawanda yemunyu we sodium citrate. Chinhu ichi chine kunaka kwakaita sesaline, kwakapfava. Uyezve, chinhu ichi hachina kunyanya kuoma, uye tinogona kuchishandisa kugadzira buffer solutions pamwe chete ne citric acid. Chinhu ichi chinoratidzika seupfu hwe crystalline chena. Kunyanya, sodium citrate inoshandiswa muindasitiri yechikafu sechinhu chinowedzera chikafu, se flavouring kana se preservative.
