Muva nje, kube nokubonisana kontanga okuningi.Lapho kuhlolwa inani eliphelele lezinto ze-nitrogen ne-ammonia nitrogen endle, ibhodlela lamanzi elifanayo ngezinye izikhathi linesimo sokuthi inani le-ammonia nitrogen lingaphezulu kwengqikithi ye-nitrogen.Angazi kungani.Lapha ngifingqa okunye okuhlangenwe nakho futhi ngihlanganyele nawe.
1.Ubudlelwano phakathi kwe-nitrogen ephelele ne-ammonia nitrogen.
Ingqikithi ye-nitrogen iyisamba se-nitrogen encibilikisiwe kanye ne-nitrogen emisiwe kusampula engalinganiswa ngaphansi kwezimo ezishiwo ezingeni.
I-ammonia nitrogen ikhona ngendlela ye-ammonia yamahhala noma i-ammonium ions.
Kuyabonakala kulokhu ukuthi inayithrojeni isiyonke iqukethe i-ammonia nitrogen, futhi ngokwethiyori ingqikithi ye-nitrogen iyoba nkulu kuphela noma ilingane ne-ammonia nitrogen.
2.Kungani inani le-ammonia nitrogen liphakeme kunevelu yengqikithi ye-nitrogen ekuhlolweni kwangempela?
Njengoba ingekho inkolelo-mbono yokuthi i-ammonia nitrogen inkulu kune-nitrogen ephelele, kungani ngezinye izikhathi kwenzeka ekuhlolweni kwangempela?Abahloli abaningi baye bahlangabezana nalesi simo, futhi abanye abacwaningi benze izifundo ezihlosiwe.Iningi lezizathu likuhlelo lokuhlola.
①Enqubweni yokutholwa kwenani le-nitrogen, ukugayeka kwezinga lokushisa eliphezulu kuyadingeka.Uma izinga lokushisa liphansi kakhulu, ukuguqulwa okungaphelele kuzoholela emiphumeleni ephansi.
②Uma isikhathi sokugaya singanele, ukuguqulwa akukaqedi, okuzokwenza ukuthi umphumela we-nitrogen ube phansi.
③Phakathi nenqubo yokuthola, ngezinye izikhathi isivimbeli asiqiniswa phakathi nenqubo yokugaya, futhi i-ammonia nitrogen iyaphuma, okuzokwenza futhi umphumela ube phansi.Ikakhulukazi lapho okuqukethwe kwe-ammonia nitrogen kusampula yamanzi kuphezulu, i-ammonia nitrogen ayiguqulwa ibe yi-nitrate nitrogen, futhi umphumela we-nitrogen ephelele uzoba ngaphansi kunomphumela we-ammonia nitrogen.
④Izimbangela ezivamile zamaphutha ekuhloleni.Isibonelo, amasampula awazange aqoqwe futhi agcinwe ngokuhambisana nezincazelo, futhi ezinye iziphazamiso zethulwa.ukwelapha kwangaphambili okufana nokususwa kokuphazanyiswa kwe-turbidity akwenziwanga.kwakungekho siqinisekiso sendawo engenayo i-ammonia endaweni yokuhlola, futhi kwakukhona ukugxila okuphezulu kwe-ammonia nitrogen.
⑤Kubangelwa izinkinga ngama-reagents.Isibonelo, i-potassium persulfate ingcolile lapho ithola i-nitrogen isiyonke, i-reagent ye-Nessler iyawohloka lapho ithola i-ammonia nitrogen, futhi ukunemba kwejika elijwayelekile akuhlolisiswa ngesikhathi..
Ukwengeza, amaphutha abangelwa abahlaziyi kanye nemishini yokuhlaziya, njengokunqunywa kwe-ammonia nitrogen kanye nenani le-nitrogen, ngokuvamile kwenziwa abahlaziyi abahlukene, ngezinye izikhathi ngezinsuku ezihlukene ngemishini ehlukene, okuzodala amaphutha athile.
3.Ungalehlisa kanjani iphutha lokutholwa?
Ngemva kokuhlaziya okungenhla, umhleli ukholelwa ukuthi lezi zinyathelo ezilandelayo zingasiza wonke umuntu ehlise iphutha ekutholeni ingqikithi ye-nitrogen ne-ammonia nitrogen.
①Khetha ama-reagents aqediwe ajwayelekile.Ukutholwa kwezinto eziphelele ze-nitrogen ne-ammonia nitrogen kudinga ama-reagents ahlukahlukene, inqubo yokuzilungiselela inzima futhi ukulawula ikhwalithi kunzima, futhi kunzima ukuxazulula izinkinga lapho izinkinga zenzeka.
②Enqubweni yokuhlola amasampula, kusetshenziswa izindlela ezahlukahlukene zokulawula ikhwalithi.Isibonelo, ekuhlolweni okungenalutho, lapho ukuhlolwa okungenalutho kungavamile, hlola ukungcoliswa kwamanzi okuhlola, ama-reagents, izitsha, njll. Ngesikhathi esifanayo, kungenza amasampula ahambisanayo futhi kwengeze amasampula ajwayelekile ukuze kunqunywe.Yenza isampula evamile yephoyinti lokugxilisa ingqondo phakathi kwejika elijwayelekile, kanye nezinyathelo ezihlukahlukene zokuqinisekisa ukuthi lonke uhlelo lokuhlola luyalawulwa.Ungakhetha okokusebenza kokuhlola ngemisebenzi yokulawula ikhwalithi ukuze unciphise ubunzima bokusebenza kokulawula ikhwalithi.
③Naka imininingwane ohlelweni lokuhlola.Isibonelo, isikhathi sokugaya kanye nezinga lokushisa kufanele kuhambisane nebhukwana lokusebenza.Qinisa isivalo sebhodlela ngesikhathi sokugaya.Qoqa futhi ugcine amasampula amanzi ngokuya ngemibandela.Hlola ingqikithi ye-nitrogen ne-ammonia nitrogen endaweni yaselabhorethri engenayo i-ammonia.Sebenzisa i-hydrochloric acid 1+9 noma i-sulfuric acid 1+35 kuma-glassware.cwilisa.Hlanza ngamanzi ompompi bese uhlanza ngamanzi angenayo i-ammonia izikhathi eziningana.Sebenzisa ngokushesha ngemva kokugeza.
Okungenhla okunye kokuhlangenwe nakho kwethu okusekelwe ekusebenzeni kwethu.Uma ochwepheshe benezindlela ezingcono noma iziphakamiso, ungashiya umlayezo ekhasini lethu lewebhu, futhi sizofingqa futhi sizithuthukise esikhathini esizayo.
