EDTA Cov Kev Sib Tw Los Ntawm Kev Ntseeg

Xi'an Naturetech Co., Ltd | Updated: Sep 11, 2017

Tus EDC chelating tus neeg sawv cev yog ib txoj hauv kev uas muaj kev sib haum xeeb los ntawm chelating lub nplhaib uas muaj ob lossis ntau dua ligands nrog tib lub qhov rooj hlau.

Kuj hu ua chelation los yog chelation effect. Chem ligating (uas muaj ob lossis ntau tshaj ligands nrog leeg ob leeg lub xaim hluav taws xob) ua ob lossis ntau ntau cov kev sib koom ua ke nrog lub hauv paus ion los ua ib qho kev sib hloov, piv txwv, chelate Cov tshuaj tiv thaiv ntawm. Piv txwv li ethylenediaminetetraacetic acid [EDTA, (OOCCH2) 2NCH2CH2N (CH2COO-) yuav kis tau los ntawm plaub (qee zaum peb) pawg carboxylic acid thiab ntau hlau ions xws li Fe, Th, Hg, Cu, Ni, Pb thiab cov zoo li Ob lub xos yuav tsum ua kom tau tsib daim ntawv tsib chelating ua ke los ua cov hlau-EDTA chelates uas muaj kev ruaj ntseg siab tshaj qhov sib txawv. Lub chelation ntawm co nyob hauv dej thiab cov dej khib nyiab muaj cov nyhuv tseem ceeb ntawm kev tsiv teb tsaws, txoj hmoo los yog toxicity ntawm hnyav hlau ntsiab lus nyob hauv ib puag ncig. Nyob rau hauv cov kab hlau ions muaj qhov pom tseeb, siab ceev.

Tshawb Fawb Txog ntawm EDTA Chelate

Yog hais tias lub ligand thiab nyiaj ions ua ke, cheeb tsam UV pom tau hloov lawm, koj tuaj yeem siv UV spectroscopy los txiav txim siab txog cov tshuaj tiv thaiv; Yog tias tsis muaj kev hloov kho qhov muag, koj tuaj yeem siv tau electrochemical txhais tau tias, nyiaj dawb - nyiaj dawb chloride txiav txim siab ntawm dawb nyiaj ions Concentration; yog tias nws yog qhov khoom, tsuas yog qhov hnyav siv los ntxuav cov khoom, dawb nyiaj ions elute, thiab ces siv atomic absorption los yog lwm yam txhais tau tias txhom tau cov nyiaj ion

Ib qho kev sib thooj uas muaj ib qho polygene ligand muaj peev xwm ntawm chelating nrog ib tug hlau ion tsim ib tug chelate. Hauv cov dej khib nyiab dej, cov neeg mob cov organic xws li aminocarbons (xws li NTA, ethylenediaminetetraacetic acid, EDTA, thiab lwm yam.), Dithizone, 8-hydroxyquinoline, (C12H8N2), sodium potassium tartrate, ammonium citrate thiab inorganic chelating agents. Cov neeg ua hauj lwm rau kev cheb muaj kev xaiv siab thiab rhiab heev rau ntau hom hlau ions, thiab cov hlau ua tau zoo muaj zog zoo dua li cov sib luag. Nyob rau hauv tej huab cua phem chemical thiab chemical kev lag luam, feem ntau raws li complexing titrant, hlau qhia, hlau sib cais, antioxidant, masking tus neeg sawv cev, mus rau scale agent, algae agent, flotation tus neeg sawv cev, fungicide thiab li on. Tshwj xeeb tshaj yog nyob rau hauv dej zoo, kev txiav txim ntawm dej hardness, hlau ion concentration tau dav siv
