Ƙaramin ilimi da babban ilimi 丨 Jimlar daidaitaccen samfurin phosphorus na tsari

Daidaita samfuran da aka saba da su abu ne da ake buƙatar a yi akai-akai a lokacin gwaje-gwaje. Idan aka ɗauki gwajin da ya shafi gwajin alamun ingancin ruwa a matsayin misali, ta hanyar daidaita samfuran da aka saba da su, ta hanyar kwatanta ƙimar da aka auna da ƙimar ma'aunin samfurin da aka saba da su, mutum zai iya tantance ko kuskuren kayan aikin gwaji yana cikin kewayon da aka ƙayyade, ɗayan kuma zai iya tabbatar da ko hanyar aunawa ta mai gwajin daidai ne. Saboda haka, daidaita samfuran da aka saba da su yana da matuƙar muhimmanci ga amincin gwajin.
Mai zuwa zai gabatar da tsarin tsari na jimlar samfurin phosphorus na yau da kullun, zo ku duba.
Mataki na farko shine a shirya kayan abinci na musamman na Lianhua Technology don cikakken phosphorus-potassium dihydrogen phosphate (KH2PO4), ruwan da aka tace, beaker, sandar motsawa, da kuma kwalbar volumetric 1000ml kafin a tsara su.
Mataki na biyu shine a ɗauki ƙaramin adadin potassium dihydrogen phosphate (KH2PO4) sannan a busar da shi a zafin 110℃ na tsawon awanni 2, sannan a fitar da shi bayan ya huce.
Mataki na uku shine a auna nauyin 0.2197 g na busasshen potassium dihydrogen phosphate (KH2PO4) daidai sannan a saka shi a cikin kwalba, a zuba kimanin 100 ml na ruwan da aka tace, a juya har sai ya narke gaba ɗaya, sannan a zuba 5 ml na sinadarin sulfuric acid, sannan a mayar da shi cikin kwalba mai girman girma (ana iya wanke kwalbar sau uku da ruwan da aka tace, sannan a ƙara ruwan da aka wanke a cikin kwalbar), sannan a ƙarshe a narkar da shi zuwa 1000 ml.
Yanzu, jimlar samfurin phosphorus na 50 mg/L ya shirya. Ana iya amfani da samfurin da aka shirya na yau da kullun don gwadawa da daidaita kayan aiki, kuma tsawon lokacin shiryawa gabaɗaya watanni 6 ne.
Wannan ita ce hanyar da aka tsara don jimlar samfurin phosphorus na yau da kullun a cikin wannan fitowar. Ku biyo ni don ƙarin koyo game da gwaji!
