Kutshanje, kubekho uthethwano loontanga oluninzi.Xa uvavanya i-nitrogen epheleleyo kunye ne-ammonia nitrogen izinto kwi-sewege, ibhotile enye yamanzi ngamanye amaxesha ine-phenomenon yokuba ixabiso le-ammonia nitrogen liphezulu kune-nitrogen epheleleyo.Andazi ukuba kutheni.Apha ndishwankathela amava athile kwaye ndabelana nawe.
1.Ubudlelwane phakathi kwenitrogen epheleleyo kunye ne-ammonia nitrogen.
Iyonke initrogen yinitrogen enyityilisiweyo kunye nenitrogen enqunyanyisiweyo kwisampulu enokulinganiswa phantsi kweemeko ezichazwe kumgangatho.
I-ammonia nitrogen ikhona ngohlobo lwe-ammonia yasimahla okanye i-ammonium ions.
Kunokubonwa koku ukuba initrogen iyonke iqulethe i-ammonia nitrogen, kwaye ngokwethiyori iyonke initrogen iya kuba nkulu kuphela okanye ilingane ne-ammonia nitrogen.
2.Kutheni ixabiso le-ammonia nitrogen liphezulu kunexabiso le-nitrogen epheleleyo kuvavanyo lwangempela?
Ekubeni kungekho ngcamango yokuba i-ammonia nitrogen inkulu kune-nitrogen epheleleyo, kutheni ngamanye amaxesha kwenzeka kuvavanyo lwangempela?Abahloli abaninzi baye bahlangabezana nale nto, kwaye abanye abaphandi baye baqhuba izifundo ezijoliswe kuzo.Uninzi lwezizathu zikwinkqubo yokuhlolwa.
①Kwinkqubo yokufunyaniswa kwenitrogen iyonke, kufuneka ubushushu obuphezulu bokwetyisa.Xa ubushushu buphantsi kakhulu, ukuguqulwa okungaphelelanga kuya kukhokelela kwiziphumo eziphantsi.
②Xa ixesha lokugaya linganele, ukuguqulwa akuphelelanga, okuya kubangela ukuba isiphumo se-nitrogen sibe phantsi..
③Ngethuba lenkqubo yokufumanisa, ngamanye amaxesha isithinteli asiqiniswanga ngexesha lokugaya, kwaye i-ammonia nitrogen ibalekela, nayo iya kubangela ukuba umphumo ube phantsi.Ngokukodwa xa umxholo we-ammonia nitrogen kwisampuli yamanzi iphezulu, i-nitrogen ye-ammonia ayiguqulwa ibe yi-nitrojeni ye-nitrate, kwaye umphumo we-nitrogen epheleleyo uya kuba ngaphantsi kwesiphumo se-ammonia nitrogen.
④Izizathu eziqhelekileyo zeempazamo kuvavanyo.Ngokomzekelo, iisampulu azizange ziqokelelwe kwaye zigcinwe ngokuhambelana neenkcukacha, kunye nezinye iziphazamiso zaziswa.Unyango lwangaphambili olufana nokususwa kophazamiseko lwe-turbidity ayenziwanga.kwakungekho siqinisekiso semekobume engena-ammonia kwindawo yovavanyo, kwaye bekukho ukugxilwa okuphezulu kwe-ammonia nitrogen.
⑤Ibangelwa yingxaki kunye ne-reagents.Ngokomzekelo, i-potassium persulfate ayicocekanga xa ibona i-nitrogen epheleleyo, i-reagent ye-Nessler iyawohloka xa ibona i-ammonia nitrogen, kwaye ukuchaneka kwegophe elisemgangathweni akujongwa ngexesha..
Ukongezelela, iimpazamo ezibangelwa ngabahlalutyi kunye nezixhobo zokuhlalutya, ezifana nokumiselwa kwe-ammonia nitrogen kunye ne-nitrogen epheleleyo, ngokuqhelekileyo iqhutywe ngabahlalutyi abahlukeneyo, ngamanye amaxesha ngeentsuku ezahlukeneyo kunye nezixhobo ezahlukeneyo, eziza kubangela iimpazamo ezithile.
3.Indlela yokunciphisa imposiso yobhaqo?
Emva kolu hlalutyo lungentla, umhleli ukholelwa ukuba la manyathelo alandelayo anokunceda wonke umntu anciphise impazamo kwinkqubo yokufumanisa i-nitrogen epheleleyo kunye ne-ammonia nitrogen.
①Khetha ii-reagents ezigqityiweyo ezisemgangathweni.Ukufunyanwa kwezinto ze-nitrogen kunye ne-ammonia nitrogen zifuna iindidi ze-reagents, inkqubo yokuzilungiselela inzima kwaye ukulawulwa komgangatho kunzima, kwaye kunzima ukuxazulula iingxaki xa kwenzeka iingxaki.
②Kwinkqubo yokuvavanya iisampuli, iindlela ezahlukeneyo zokulawula umgangatho zisetyenziswa.Ngokomzekelo, kuvavanyo olungenanto, xa uvavanyo olungenanto lungaqhelekanga, khangela ukungcoliswa kwamanzi okuvavanya, ama-reagents, izitya, njl. Ngelo xesha, kunokwenza iisampuli ezihambelanayo kunye nokongeza iisampuli eziqhelekileyo zokumisela.Yenza isampuli esemgangathweni yendawo yokuxininisa phakathi kwinqanaba eliqhelekileyo, kunye nemilinganiselo eyahlukeneyo yokuqinisekisa ukuba yonke inkqubo yokuhlola iphantsi kolawulo.Unokukhetha izixhobo zokuvavanya kunye nemisebenzi yokulawula umgangatho ukunciphisa ubunzima bemisebenzi yokulawula umgangatho.
③Nika ingqalelo kwiinkcukacha kwinkqubo yokuhlola.Umzekelo, ixesha lokwetyisa kunye nobushushu kufuneka buhambelane nencwadana yokusebenza.Qinisa umnqwazi webhotile ngexesha lokwetyisa.Qokelela kwaye ugcine iisampulu zamanzi ngokweenkcukacha.Vavanya initrogen epheleleyo kunye ne-ammonia nitrogen kwindawo yelabhoratri engena-ammonia.Sebenzisa i-hydrochloric acid 1+9 okanye i-sulfuric acid 1+35 kwi-glassware.cwina.Hlanza ngamanzi epompo uze uhlanjululwe ngamanzi angenayo i-ammonia amaxesha amaninzi.Sebenzisa ngokukhawuleza emva kokuhlamba.
Oku kungasentla ngamanye amava ethu asekelwe kwindlela esisebenza ngayo.Ukuba iingcali zineendlela ezingcono okanye iingcebiso, unokushiya umyalezo kwiphepha lethu lewebhu, kwaye siya kushwankathela kwaye siphucule kwixesha elizayo.
