Ammonium sulfate granular (ọkwa ígwè)

Isi ojiji nke ammonium sulfate bụ fatịlaịza maka ala alkaline.N'ime ala, a na-ahapụ ion ammonium ma mepụta obere acid, na-ebelata nguzozi pH nke ala, ebe ọ na-enye onyinye nitrogen dị mkpa maka uto osisi.Ihe ọghọm dị na iji ammonium sulfate bụ obere nitrogen ọdịnaya metụtara ammonium nitrate, nke na-ebuli ọnụ ahịa njem.

A na-ejikwa ya dị ka ihe enyemaka ịgbasa ugbo maka ụmụ ahụhụ na-agbaze mmiri, ahịhịa na fungicides.N'ebe ahụ, ọ na-arụ ọrụ iji jikọta ígwè na calcium cations nke dị na ma mmiri olulu mmiri na mkpụrụ ndụ osisi.Ọ dị irè karịsịa dị ka ihe enyemaka maka 2,4-D (amine), glyphosate, na glufosinate herbicides.

Ammonium sulfate mmiri ozuzo bụ usoro a na-ejikarị eme ka protein dị ọcha site na mmiri ozuzo.Ka ike ionic nke ngwọta na-abawanye, ike nke protein na ngwọta ahụ na-ebelata.Ammonium sulfate na-agbaze nke ukwuu na mmiri n'ihi ọdịdị ionic ya, ya mere ọ nwere ike "ịgbapụta" protein site na mmiri ozuzo.N'ihi oke dielectric mmiri na-adịgide adịgide, ion nnu ndị a kewapụrụ bụ cationic ammonium na anionic sulfate na-agbaze ngwa ngwa n'ime shei hydration nke ụmụ irighiri mmiri.Ihe dị n'ime ihe a dị na nchacha nke ogige sitere na ikike ya ị nweta hydrated karịa ma e jiri ya tụnyere ụmụ irighiri ihe ndị a na-achọsi ike, ya mere, ụmụ irighiri ihe ndị a na-achọsi ike na-agbakọta ma na-esi na ngwọta ya pụta n'ụdị siri ike.A na-akpọ usoro a ka a na-ewepụ nnu ma na-achọ ka a na-eji nnu dị elu nke nwere ike ịgbaze na ngwakọta mmiri.Pasent nke nnu a na-eji tụnyere ọnụ ọgụgụ kachasị elu nke nnu na ngwakọta nwere ike igbari.N'ihi ya, ọ bụ ezie na ọ dị mkpa itinye uche dị elu ka usoro ahụ na-arụ ọrụ na-agbakwụnye ụbara nnu, ihe karịrị 100%, nwekwara ike mebie ihe ngwọta ya, ya mere, na-eji nnu na-asọpụta mmiri na-adịghị na polar.Nnukwu nnu nnu, nke a ga-enweta site n'ịgbakwunye ma ọ bụ ịba ụba nke ammonium sulfate na ngwọta, na-eme ka nkewa protein dị iche iche dabere na mbelata nke solubility protein;Enwere ike nweta nkewa a site na centrifugation.Mmiri mmiri ozuzo site na ammonium sulfate bụ n'ihi mbelata nke solubility kama ịbụ protein denaturation, ya mere enwere ike ime ka protein a na-agbapụta agbaze site na iji ọkọlọtọ ọkọlọtọ.[5].Ammonium sulfate mmiri ozuzo na-enye ụzọ dị mfe ma dị mfe iji mebie ngwakọta protein dị mgbagwoju anya.

Na nyocha nke lattices roba, a na-enyocha acids fatty na-agbanwe agbanwe site na rọba na-ebupụta ya na 35% ammonium sulfate solution, nke na-ahapụ mmiri mmiri doro anya nke na-eme ka acid fatty na-agbanwe agbanwe na sulfuric acid wee gbanye ya na uzuoku.Nhọrọ nke oke mmiri ozuzo nwere ammonium sulfate, megidere usoro mmiri ozuzo na-emebu nke na-eji acetic acid, anaghị egbochi mkpebi nke acid fatty na-agbanwe agbanwe.

-Ihe mgbakwunye nri

Dị ka ihe mgbakwunye nri, a na-ahụta ammonium sulfate dị ka nchekwa (GRAS) site na nchịkwa nri na ọgwụ US, yana na European Union họpụtara ya site na nọmba E517.A na-eji ya dị ka onye na-achịkwa acidity na ntụ ọka na achịcha.

-Ojiji ndị ọzọ

Na ọgwụgwọ nke mmiri ọṅụṅụ, ammonium sulfate na-ejikọta ya na chlorine iji mepụta monochloramine maka nsị.

A na-eji ammonium sulfate mee ihe n'obere ọnụ ọgụgụ na nkwadebe nke nnu ammonium ndị ọzọ, karịsịa ammonium persulfate.

Edepụtara Ammonium sulfate dị ka ngwa ngwa maka ọtụtụ ọgwụ mgbochi United States kwa erslọ Ọrụ Maka Nchịkwa Ọrịa.

A na-eji ngwọta zuru ezu nke ammonium sulfate na mmiri dị arọ (D2O) mee ihe dị ka ọkọlọtọ mpụga na sọlfọ (33S) NMR spectroscopy na uru mgbanwe nke 0 ppm.

A na-ejikwa ammonium sulfate mee ihe n'ime ihe ndị na-egbochi ọkụ na-eme ihe dị ka diammonium phosphate.Dị ka ihe na-egbochi ire ọkụ, ọ na-abawanye okpomọkụ ọkụ nke ihe ahụ, na-ebelata oke ọnwụ ọnwụ, ma na-ebute mmụba na mmepụta ihe fọdụrụ ma ọ bụ char.[14].Enwere ike ịkwalite nrụpụta ọkụ ya site na ịgwakọta ya na ammonium sulfate.

A na-eji Ammonium sulfate mee ihe dị ka ihe nchekwa osisi, mana n'ihi ọdịdị hygroscopic ya, a kwụsịrị iji nke a n'ụzọ dị ukwuu n'ihi nsogbu ndị metụtara ya na nrụrụ ígwè, nkwụsị nke akụkụ, na njedebe ọdịda.
