Cov txiaj ntsig ntawm Ammonium Sulfate li Fertilizer

Thawj qhov kev siv ammonium sulfate yog ua chiv rau alkaline av. Hauv cov av, ammonium ion raug tso tawm thiab tsim cov kua qaub me me, txo qis pH ntawm cov av, thaum txhawb nqa qhov tseem ceeb nitrogen rau cov nroj tsuag loj hlob. Lub ntsiab tsis zoo rau kev siv ammonium sulfate yog nws cov ntsiab lus tsis tshua muaj nitrogen txheeb ze rau ammonium nitrate, uas txhawb nqa cov nqi tsheb thauj mus los.

Nws kuj tseem siv tau los ua cov tshuaj tsuag ua liaj ua teb rau cov tshuaj tua kab hauv dej, tshuaj tua kab mob, thiab fungicides. Nyob ntawd, nws ua haujlwm los khi hlau thiab calcium cations uas muaj nyob rau hauv ob qho tib si dej thiab cov nroj tsuag hlwb. Nws yog tshwj xeeb tshaj yog zoo li ib tug adjuvant rau 2,4-D (amine), glyphosate, thiab glufosinate herbicides.

Ammonium sulfate nag lossis daus yog ib txoj hauv kev rau kev ntxuav cov protein los ntawm nag lossis daus. Raws li lub zog ionic ntawm cov tshuaj nce ntxiv, solubility ntawm cov protein hauv cov tshuaj txo qis. Ammonium sulfate yog soluble hauv dej tsis tshua muaj vim nws qhov xwm txheej ionic, yog li nws tuaj yeem "ntse tawm" cov protein los ntawm nag lossis daus. Vim lub siab dielectric tas li ntawm dej, cov ntsev ions dissociated yog cationic ammonium thiab anionic sulfate yog nkag tau yooj yim nyob rau hauv hydration plhaub ntawm dej molecules. Qhov tseem ceeb ntawm cov tshuaj no nyob rau hauv lub purification ntawm cov tebchaw stems los ntawm nws lub peev xwm los ua ntau hydrated piv rau kuj ntau nonpolar molecules thiab yog li qhov xav tau nonpolar molecules coalesce thiab precipitate tawm ntawm cov tshuaj nyob rau hauv ib tug concentrated daim ntawv. Txoj kev no yog hu ua salting tawm thiab yuav tsum tau siv cov ntsev ntau ntau uas tuaj yeem ntseeg tau yaj hauv cov dej sib tov. Qhov feem pua ​​​​ntawm cov ntsev siv yog piv rau qhov siab tshaj plaws ntawm cov ntsev hauv qhov sib tov tuaj yeem yaj. Raws li xws li, txawm hais tias yuav tsum muaj siab concentration rau txoj kev ua hauj lwm ntxiv ib tug ntau ntawm cov ntsev, tshaj 100%, kuj muaj peev xwm oversaturate cov tshuaj, yog li ntawd, contaminating lub nonpolar precipitate nrog ntsev precipitate. Lub siab ntsev concentration, uas tuaj yeem ua tiav los ntawm kev ntxiv lossis nce cov concentration ntawm ammonium sulfate hauv kev daws, ua kom cov protein sib cais raws li qhov txo qis hauv cov protein solubility; Qhov kev sib cais no tuaj yeem ua tiav los ntawm centrifugation. Los nag los ntawm ammonium sulfate yog tshwm sim los ntawm kev txo cov solubility ntau dua li cov protein denaturation, yog li cov protein precipitated tuaj yeem solubilized los ntawm kev siv cov txheej txheem buffers.[5] Ammonium sulfate nag lossis daus muab ib qho yooj yim thiab yooj yim txhais tau tias fractionate complex protein mixs.

Hauv kev tshuaj xyuas ntawm cov roj hmab lattices, cov roj ntsha tsis hloov pauv tau raug tshuaj xyuas los ntawm cov roj hmab nag los nrog 35% ammonium sulfate tov, uas tawm cov kua ntshiab los ntawm cov roj fatty acids uas tsis hloov pauv nrog sulfuric acid thiab tom qab ntawd distilled nrog chav. Kev xaiv nag lossis daus nrog ammonium sulfate, tawm tsam rau cov txheej txheem nag lossis daus ib txwm siv acetic acid, tsis cuam tshuam nrog kev txiav txim siab ntawm cov roj fatty acids tsis haum.

- Khoom noj khoom haus additive

Raws li cov khoom noj khoom haus ntxiv, ammonium sulfate yog feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm US Food and Drug Administration, thiab hauv European Union nws raug xaiv los ntawm E tus lej E517. Nws yog siv los ua acidity regulator nyob rau hauv hmoov thiab breads.

- Lwm yam kev siv

Hauv kev kho cov dej haus, ammonium sulfate yog siv ua ke nrog cov tshuaj chlorine los tsim monochloramine rau kev tua kab mob.

Ammonium sulfate yog siv rau me me hauv kev npaj ntawm lwm yam ammonium ntsev, tshwj xeeb tshaj yog ammonium persulfate.

Ammonium sulfate tau teev tseg raws li cov khoom xyaw rau ntau lub tebchaws United States cov tshuaj tiv thaiv ntawm Lub Chaw Tiv Thaiv Kab Mob.

Ib qho kev daws teeb meem ntawm ammonium sulfate hauv dej hnyav (D2O) yog siv los ua tus qauv sab nraud hauv sulfur (33S) NMR spectroscopy nrog tus nqi hloov pauv ntawm 0 ppm.

Ammonium sulfate kuj tau siv nyob rau hauv cov nplaim hluav taws kub ua kom zoo li diammonium phosphate. Raws li cov nplaim hluav taws kub hnyiab, nws ua rau qhov kub thiab txias ntawm cov khoom siv, txo qhov hnyav tshaj qhov hnyav, thiab ua rau muaj kev nce hauv cov khoom seem lossis char.[14] Nws cov nplaim retardant kev ua tau zoo tuaj yeem txhim kho los ntawm kev sib xyaw nrog ammonium sulfamate.

Ammonium sulfate tau siv los ua cov ntoo khaws cia, tab sis vim nws qhov xwm txheej hygroscopic, qhov kev siv no tau raug txiav tawm ntau vim tias muaj teeb meem cuam tshuam nrog cov hlau fastener corrosion, qhov ntev tsis ruaj khov, thiab ua tiav tsis tiav.
