Ammonium Sulphate Granular (Gulu la Zitsulo)

Kugwiritsa ntchito kwambiri ammonium sulphate ndi monga feteleza wa dothi lamchere. M'nthaka ammonium ion imatulutsidwa ndikupanga asidi pang'ono, kutsitsa pH ya nthaka, pomwe imathandizira nayitrogeni wofunikira pakukula kwa mbewu. Choyipa chachikulu pakugwiritsa ntchito ammonium sulphate ndi kuchepa kwa nayitrogeni poyerekeza ndi ammonium nitrate, zomwe zimakweza mtengo wamayendedwe.

Amagwiritsidwanso ntchito ngati chothandizira chaulimi chamankhwala osungunuka m'madzi, ma herbicides, ndi fungicides. Kumeneko, imagwira ntchito yomanga zitsulo zachitsulo ndi calcium zomwe zimapezeka m'maselo amadzi ndi zomera. Ndiwothandiza makamaka ngati adjuvant wa 2,4-D (amine), glyphosate, ndi glufosinate herbicides.

Ammonium sulfate precipitation ndi njira yodziwika bwino yoyeretsera mapuloteni ndi mvula. Pamene mphamvu ya ionic ya yankho ikuwonjezeka, kusungunuka kwa mapuloteni mu njirayo kumachepa. Ammonium sulphate imasungunuka kwambiri m'madzi chifukwa cha chikhalidwe chake cha ayoni, chifukwa chake imatha "kutulutsa mchere" mapuloteni ndi mvula. Chifukwa cha kuchuluka kwa dielectric m'madzi, ma ion amchere omwe amasiyanitsidwa kukhala cationic ammonium ndi anionic sulfate amasungunulidwa mosavuta m'zipolopolo za hydration za mamolekyu amadzi. Kufunika kwa chinthu ichi pakuyeretsa zinthu kumachokera ku kuthekera kwake kukhala ndi madzi ochulukirapo poyerekeza ndi mamolekyu ambiri omwe si polar kotero kuti mamolekyu ofunikira a nonpolar amalumikizana ndikutuluka munjirayo mokhazikika. Njirayi imatchedwa salting out ndipo imafuna kugwiritsa ntchito mchere wambiri womwe ungathe kusungunuka mumadzi osakaniza. Kuchuluka kwa mchere womwe umagwiritsidwa ntchito poyerekeza ndi kuchuluka kwa mchere womwe uli mu osakaniza ukhoza kusungunuka. Momwemonso, ngakhale kuti kuchuluka kwakukulu kumafunikira kuti njirayo igwire ntchito ndikuwonjezera mchere wambiri, wopitilira 100%, ungathenso kuchulukitsa yankho, motero, kuyipitsa mpweya wosagwirizana ndi mchere. Kuchuluka kwa mchere wamchere, komwe kungapezeke mwa kuwonjezera kapena kuonjezera kuchuluka kwa ammonium sulfate mu njira yothetsera, kumathandizira kupatukana kwa mapuloteni chifukwa cha kuchepa kwa mapuloteni; kulekana uku kungapezeke mwa centrifugation. Kugwa kwa mpweya ndi ammonium sulfate ndi chifukwa cha kuchepa kwa kusungunuka m'malo mwa kusungunuka kwa mapuloteni, motero mapuloteni omwe amatha kusungunuka amatha kusungunuka pogwiritsa ntchito mabafa wamba.[5] Ammonium sulphate mpweya umapereka njira yosavuta komanso yosavuta yogawanitsa zosakaniza zama protein.

Pakuwunika ma latisi a raba, mafuta osasinthika amawunikidwa ndi mphira wothira ndi 35% ammonium sulfate solution, yomwe imasiya madzi omveka bwino momwe mafuta osasunthika amapangidwanso ndi sulfuric acid kenako amathiridwa ndi nthunzi. Mvula yosankha yokhala ndi ammonium sulphate, motsutsana ndi njira yanthawi zonse yamvula yomwe imagwiritsa ntchito acetic acid, sikusokoneza kutsimikiza kwamafuta acids osakhazikika.

- Zakudya zowonjezera

Monga chowonjezera chazakudya, ammonium sulfate amadziwika kuti ndi otetezeka (GRAS) ndi US Food and Drug Administration, ndipo ku European Union amasankhidwa ndi nambala E517. Amagwiritsidwa ntchito ngati chowongolera acidity mu ufa ndi mkate.

Pochiza madzi akumwa, ammonium sulphate amagwiritsidwa ntchito limodzi ndi klorini kupanga monochloramine popha tizilombo toyambitsa matenda.

Ammonium sulphate amagwiritsidwa ntchito pang'ono pokonza mchere wina wa ammonium, makamaka ammonium sulfate.

Ammonium sulphate amalembedwa ngati chogwiritsira ntchito katemera ambiri ku United States pa Centers for Disease Control.

A saturated solution ya ammonium sulfate m'madzi olemera (D2O) amagwiritsidwa ntchito ngati muyezo wakunja mu sulfure (33S) NMR spectroscopy yokhala ndi kusintha kwa mtengo wa 0 ppm.

Ammonium sulphate imagwiritsidwanso ntchito muzolemba zoletsa moto zomwe zimafanana ndi diammonium phosphate. Monga choletsa lawi, kumawonjezera kuyaka kwa zinthu, amachepetsa pazipita kuwonda mitengo, ndi kuchititsa kuwonjezeka kupanga zotsalira kapena char.[14] Mphamvu yake yoletsa moto imatha kukulitsidwa poyiphatikiza ndi ammonium sulfamate.

Ammonium sulphate yakhala ikugwiritsidwa ntchito ngati chosungira nkhuni, koma chifukwa cha chikhalidwe chake cha hygroscopic, kugwiritsa ntchito kumeneku kwathetsedwa chifukwa cha zovuta zomwe zimagwirizanitsidwa ndi zitsulo zopangira dzimbiri, kusakhazikika kwa mawonekedwe, komanso kulephera kumaliza.
