IDHA-Fe Lub npe tshuaj: Hlau iminodisuccinate sodium ntsev Tsis tau nrov, cov nyhuv tseem tsis tau txiav txim siab.
Lub npe tshuaj ntawm EDDHA-Fe: Hlau ethylenediamine o-diglycolic acid. Nroj tsuag tuaj yeem nqus tau zoo hauv av pH ntau ntawm 3-12. (Qhov siab dua tus nqi pH, qhov pom tseeb dua qhov zoo ntawm EDDHA chelated hlau tshaj EDTA chelated hlau thiab ferrous sulfate.) Cov xim feem ntau yog xim av tsaus, nrog qhov sib txawv ortho qhov tseem ceeb (tam sim no 1.8, 2.4, 3.0, 3.6, 4.8).
Lub npe tshuaj ntawm DTPA-Fe: ferric diethylene triamine pentaacetate, yog haum rau cov av uas muaj pH nqi tsawg dua 8 thiab tsis yooj yim degraded.
Lub npe tshuaj ntawm EDTA-Fe: sodium hlau ethylenediaminetetraacetate, yog haum rau cov av uas muaj pH qis dua 7 thiab tsis yooj yim degraded.
FeSO4 yog ib hom tshuaj chiv uas yog ib txwm tsis nqus los ntawm cov nroj tsuag thaum cov av pH ntau dua 7. Nws yog inorganic, tsis ruaj khov, thiab yooj yim oxidized rau trivalent hlau.
EDDHA-Fe, DTPA-Fe, EDTA-Fe, thiab FeSO4 yog txhua yam siv hlau chiv niaj hnub no. Kev nqus tau zoo ntawm chelated hlau chiv yog ntau dua li cov chiv uas tsis yog chelated hlau. EDDHA-Fe muaj kev ua haujlwm lom neeg ntau dua li ob hom chelated hlau, DTPA-Fe thiab EDTA-Fe. Nws muaj pH dav thiab zoo dua li lwm cov chiv hlau.
