EDTA-ACID Cov
EDTA muaj ntau pawg carboxylic acid (-COOH) thiab amino pawg (-NH2), uas tuaj yeem tsim cov hexagonal ruaj khov nrog cov hlau ions. Lub pH ntawm nws cov tshuaj tuaj yeem hloov kho los ntawm kev ntxiv cov kua qaub lossis lub hauv paus. Cov kua qaub uas muaj xws li hydrochloric acid (HCl), thaum lub hauv paus muaj xws li sodium hydroxide (NaOH). nws yog ib tug dawb crystalline hmoov, soluble nyob rau hauv dej los tsim ib tug colorless tov. Lub solubility ntawm nws nyob rau hauv dej yog cuam tshuam los ntawm pH nqi, thiab solubility yog siab dua nyob rau hauv alkaline tej yam kev mob. Thaum nws ntxiv rau dej, nws maj mam yaj los ua ib qho kev daws teeb meem pob tshab. Yog tias pH ntawm cov tshuaj yog qis, koj tuaj yeem pom pH nce ntxiv vim tias nws yuav haus hydrogen ions. Yog hais tias insoluble hlau ntsev precipitate nyob rau hauv cov kev daws, lub precipitate yuav yaj tom qab ntxiv ntawm nws, vim hais tias nws tsim soluble complexes nrog hlau ions.

EDTA yog ib tug tseem ceeb complexing neeg sawv cev. Nws yog dav siv, yuav siv tau raws li cov xim photosensitive cov ntaub ntawv ntxuav ua bleaching kho tov, dyeing AIDS, fiber kho mob AIDS, tshuaj pleev ib ce additives, ntshav anticoagulant, detergent, stabilizer, hluavtaws roj hmab polymerization pib, nws yog ib tug neeg sawv cev ntawm chelating tus neeg sawv cev. Nws tuaj yeem tsim cov dej-soluble complexes ruaj khov nrog alkaline ntiaj teb hlau, tsis tshua muaj ntiaj teb cov ntsiab lus thiab cov hlau hloov pauv. Ntxiv nrog rau cov ntsev ntsev, muaj ammonium ntsev thiab hlau, magnesium, calcium, tooj liab, manganese, zinc, cobalt, txhuas thiab lwm yam ntsev, uas muaj ntau yam kev siv. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov hlau tsis zoo hauv lub cev sai sai los ua lub luag haujlwm detoxification. Nws kuj yog ib qho tshuaj kho dej. nws kuj yog ib qho tseem ceeb qhia, tab sis siv rau titrate hlau npib tsib xee, tooj liab, thiab lwm yam, thaum siv nrog ammonia, thiaj li ua si lub luag hauj lwm ntawm qhov taw qhia.
