Munguva pfupi yapfuura, kwave kune kubvunzana kwevezera kwakawanda.Paunenge uchiyedza iyo yakazara nitrogen uye ammonia nitrogen zvinhu mumvura yetsvina, bhodhoro rimwechete remvura dzimwe nguva rine chiitiko chekuti ammonia nitrogen kukosha kwakakwira kupfuura iyo yakazara nitrogen.Handizivi kuti sei.Pano ndinopfupikisa zvimwe zviitiko uye ndinogoverana newe.
1.Ukama huri pakati penitrogen yakazara uye ammonia nitrogen.
Total nitrogen ihuwandu hwenitrogen yakanyungudutswa uye nitrogen yakaturikwa mumuenzaniso inogona kuyerwa pasi pemamiriro akataurwa muchiyero.(Kusanganisira nitrogen munitrite nitrogen, nitrate nitrogen, inorganic ammonium salt, dissolved ammonia uye akawanda organic nitrogen compounds).
Ammonia nitrogen iripo muchimiro chemahara ammonia kana ammonium ions.
Zvinogona kuonekwa kubva pane izvi kuti nitrogen yese ine ammonia nitrogen, uye ne theoretically yakazara nitrogen inongove yakakura kudarika kana kuenzana neammonia nitrogen.
2.Sei kukosha kweammonia nitrogen yakakwirira kudarika kukosha kwenitrogen yakazara mumuedzo chaiwo?
Sezvo pasina dzidziso yokuti ammonia nitrogen yakakura kudarika nitrogen yose, nei dzimwe nguva ichiitika mukuedzwa chaiko?Vaongorori vazhinji vakasangana nechiitiko ichi, uye vamwe vaongorori vakaita zvidzidzo zvakanangwa.Zvizhinji zvezvikonzero zviri muchirongwa chekuongorora.
①Mukuita kwekuonekwa kwakazara nitrogen, kupisa kwakanyanya kunodiwa.Kana tembiricha yakadzikira, shanduko isina kukwana inotungamira kune yakaderera mhedzisiro.
②Kana nguva yekugaya isina kukwana, kutendeuka hakuna kukwana, izvo zvichaitawo kuti mugumisiro we nitrogen uve wakaderera..
③Munguva yekuona nzira, dzimwe nguva chivharo hachina kusimbiswa panguva yekudya, uye ammonia nitrogen inopukunyuka, iyo ichaitawo kuti chigumisiro chive chakaderera.Kunyanya kana zvinyorwa zveammonia nitrogen mumvura sampuli yakakwirira, ammonia nitrogen haina kuchinjwa kuva nitrate nitrogen, uye mugumisiro we nitrogen yose ichave yakaderera kupfuura mugumisiro weammonia nitrogen.
④Zvinowanzokonzera kukanganisa mukuedzwa.Semuenzaniso, sampuli hadzina kuunganidzwa uye kuchengetwa maererano nezvakatsanangurwa, uye zvimwe zvinokanganisa zvakaunzwa.kusati kwaitwa kurapwa kwakadai sekubvisa kupindira kwe turbidity hakuna kuitwa.pakanga pasina vimbiso yenzvimbo isina ammonia munzvimbo yekuedza, uye pakanga pane huwandu hweammonia nitrogen.
⑤Zvinokonzerwa nematambudziko ane reagents.Semuyenzaniso, potassium persulfate haina kuchena kana ikaona nitrogen yakazara, Nessler's reagent inodzikira kana ikaona ammonia nitrogen, uye huchokwadi hweiyo curve yakajairwa haitariswe nenguva..
Mukuwedzera, kukanganisa kunokonzerwa nevanoongorora uye midziyo yekuongorora, yakadai sekugadzirisa ammonia nitrogen uye nitrogen yakazara, inowanzoitwa nevanoongorora vakasiyana, dzimwe nguva pamazuva akasiyana nemichina yakasiyana, iyo inokonzera zvimwe zvikanganiso.
3.Nzira yekudzikisa kukanganisa kwekuona?
Mushure mekuongorora kuri pamusoro apa, mupepeti anotenda kuti matanho anotevera anogona kubatsira munhu wese kuderedza kukanganisa mukuonekwa kweiyo nitrogen uye ammonia nitrogen.
①Sarudza zvakamira zvakapedzwa reagents.Kuonekwa kwezvinhu zvose zve nitrogen uye ammonia nitrogen zvinoda zvakasiyana-siyana zvema reagents, nzira yekuzvigadzirira inorema uye kutonga kwehutano kwakaoma, uye zvakaoma kugadzirisa kana matambudziko aitika.
②Mukuita kwekuyedza masampula, akasiyana emhando yekudzora matanho anoshandiswa.Semuenzaniso, mukuedzwa kusina chinhu, kana muedzo usina chinhu usina kujairika, tarisa kusvibiswa kwemvura yekuedza, reagents, midziyo, nezvimwewo.Ita sampuli yakajairwa yenzvimbo yekusimbisa pakati peiyo yakajairwa curve, uye akasiyana matanho ekuona kuti iyo yese yekuongorora system iri pasi pekutonga.Iwe unogona kusarudza michina yekuyedza ine mhando yekudzora mabasa kuti uderedze kuomarara kwemhando yekudzora mashandiro.
③Nyatsoteerera kune ruzivo muchirongwa chekuongorora.Semuenzaniso, nguva yekugaya uye tembiricha inofanirwa kuenderana nebhuku rekushandisa.Simbisa chivharo chebhodhoro panguva yekugaya.Unganidza uye chengeta sampuli dzemvura maererano nezvinodiwa.Yedza yakazara nitrogen uye ammonia nitrogen munzvimbo isina ammonia-isina marabhoritari.Shandisa hydrochloric acid 1+9 kana sulfuric acid 1+35 ye glassware.soak.Shamba nemvura yepombi wozogeza nemvura isina ammonia kakawanda.Shandisa pakarepo mushure mekugeza.
Zviri pamusoro ndezvimwe zvezviitiko zvedu zvichibva pakuita kwedu pachedu.Kana nyanzvi dziine nzira dziri nani kana mazano, unogona kusiya meseji pane yedu peji rewebhu, uye isu tichapfupisa nekuvavandudza mune ramangwana.
