Ukumisela iisampulu ezisemgangathweni yinto ekufuneka yenziwe rhoqo ngexesha lovavanyo. Ukuthatha uvavanyo olunxulumene neempawu zokuvavanya umgangatho wamanzi njengomzekelo, ngokumisela iisampulu ezisemgangathweni, ngokuthelekisa ixabiso elilinganisiweyo nexabiso lesalathiso sesampulu esemgangathweni, umntu unokugqiba ukuba impazamo yesixhobo sokuvavanya ingaphakathi koluhlu oluchaziweyo, kwaye omnye unokuqinisekisa ukuba indlela yokulinganisa yomvavanyi ichanekile na. Ke ngoko, ukumisela iisampulu ezisemgangathweni kubaluleke kakhulu ekuthembekeni kovavanyo.
Oku kulandelayo kuza kwazisa inkqubo yokumisela iisampulu ze-ammonia nitrogen ezisemgangathweni, yiza uze kujonga.
Inyathelo lokuqala kukulungiselela izinto ezikhethekileyo ezisetyenziswa yiLianhua Technology ze-ammonia nitrogen-ammonium chloride (NH4Cl), amanzi acociweyo, i-beaker, intonga yokuxubha, kunye neflaski ye-volumetric ye-1000mL ngaphambi kokuba icwangciswe.
Inyathelo lesibini kukuthatha inani elincinci le-ammonium chloride (NH4Cl) uze uyomise kwi-100℃ kangangeeyure ezi-2, uze uyikhuphe emva kokuba ipholile.
Inyathelo lesithathu kukulinganisa ngokuchanekileyo i-0.3819 g ye-ammonium chloride eyomileyo (NH4Cl) uze uyifake kwi-beaker, wongeze amanzi amancinci acociweyo, uvuselele ide inyibilike ngokupheleleyo, uze uyidlulisele kwi-volumetric flask (i-beaker ingahlanjwa kathathu ngamanzi acociweyo, kwaye isisombululo sokuhlamba sifakwe kwi-volumetric flask), kwaye ekugqibeleni inyibilike ukuya kwi-1000 mL.
Ngoku, isampulu ye-ammonia nitrogen eyi-100 mg/L sele ilungile. Isampulu esemgangathweni elungisiweyo ingasetyenziselwa ukuvavanya nokulinganisa izixhobo, kwaye ubomi beshelufu ngokubanzi ziinyanga ezi-3.
Le ingentla yindlela yokulungiselela isampuli ye-ammonia nitrogen esemgangathweni kule ngxaki. Ndilandele ukuze ufunde ulwazi oluthe kratya ngovavanyo!
