Bala ubuhle ukugayeka kokudla kanye ziphuzo zazihluzwa nemingcele for the ukuzimisela nitrogen ngokusho Kjeldahl. The wokubala Imiphumela ukugayeka nemingcele ezilandelayo:
- Number of Kjeldahl Tablets (noma isisindo powder)
- Volume of sulfuric acid
Ziphuzo zazihluzwa nemingcele
- Volume amanzi dilution
- Volume of sodium hydroxide for alkalization
Titration nemingcele
- Titrant ukusetshenziswa for izikhala
- Titrant ukusetshenziswa for the isampula
- Kubalwa nitrogen lemali per isampula tube
It futhi liqukethe ukwaziswa okuwusizo kwezinye nemingcele ezifana ukugayeka kanye ziphuzo zazihluzwa isikhathi, pH kanye umthamo we boric acid kanye namandla isitimu.
Ukubala isekelwe manifold inqubo kokwenziwayo. Amathebula, emagrafu, amathiphu kanye nezincwadi ezibhekisela basize baqonde isizinda theory kodwa imiphumela ezingokoqobo izenzo ezilandelayo:
- Boric acid lokuhlushwa
- Usayizi Sample tube
- Type of ziphuzo zazihluzwa (vs. ngqo Kjeldahl standard)
- Type of kulethe (I uhlobo vs. powder)
- Titrant esejwayelekile
- Uhlobo Sample and lemali
