Ukuhlela amasampula ajwayelekile kuyinto edinga ukwenziwa njalo ngesikhathi sokuhlolwa. Uma sithatha ukuhlolwa okuhlobene nokuhlola izinkomba zekhwalithi yamanzi njengesibonelo, ngokuhlela amasampula ajwayelekile, ngokuqhathanisa inani elilinganisiwe nenani elibhekiselwe lesampula ejwayelekile, umuntu anganquma ukuthi iphutha lethuluzi lokuhlola lingaphakathi kobubanzi obubekiwe, kanti omunye angaqinisekisa ukuthi indlela yokulinganisa yomhloli ilungile yini. Ngakho-ke, ukuhlela amasampula ajwayelekile kubaluleke kakhulu ekuthembekeni kokuhlolwa.
Okulandelayo kuzokwethula inqubo yokucushwa kwamasampula ajwayelekile e-ammonia nitrogen, woza uzobheka.
Isinyathelo sokuqala ukulungiselela izinto ezikhethekile ze-Lianhua Technology ze-ammonia nitrogen-ammonium chloride (NH4Cl), amanzi acwengekile, i-beaker, induku yokuxuba, kanye ne-flask yevolumu engu-1000mL ngaphambi kokuyilungiselela.
Isinyathelo sesibili ukuthatha inani elincane le-ammonium chloride (NH4Cl) bese uyomisa ku-100℃ amahora ama-2, bese uyikhipha ngemva kokupholisa.
Isinyathelo sesithathu ukukala ngokunembile u-0.3819 g we-ammonium chloride eyomile (NH4Cl) bese uyibeka ebhekheni, engeza amanzi amancane acwengekile, uvuselele kuze kuncibilike ngokuphelele, bese udlulisela ebhekheni elinomthamo (ibhekheni lingahlanzwa kathathu ngamanzi acwengekile, bese isixazululo sokuhlanza singezwa ebhekheni elinomthamo), bese ekugcineni sincibilika sibe yi-1000 mL.
Manje, isampula ejwayelekile ye-ammonia nitrogen engu-100 mg/L isilungile. Isampula ejwayelekile elungiselelwe ingasetshenziswa ukuhlola nokulinganisa amathuluzi, futhi isikhathi sokuphelelwa yisikhathi ngokuvamile siyizinyanga ezi-3.
Okungenhla kuyindlela yokulungiselela isampula ejwayelekile ye-ammonia nitrogen kule nkinga. Ngilandele ukuze ufunde ulwazi olwengeziwe lokuhlola!
