Odsesajte tekočino iz lončka.
Drain the crucible with suction.
Operite ostanek s približno 1 litrom vroče vode temperature od 70 - 80 oC, tako da z njo postopoma polnite lonček.
Wash the residue with about 1 litre of hot water at 70 ‐ 80 ºC, filling the crucible each time.
Po vsaki napolnitvi lončka z vodo le-to kratko odsesavajte, vendar šele po tem, ko odteče zaradi težnosti.
After each addition of water, apply suction briefly but not until the water has drained under gravity.
Če izpiralna tekočina odteka skozi lonček prepočasi, lahko uporabite rahlo odsesavanje.
If the washing liquor drains through the crucible too slowly slight suction may be applied.

Podroben opis postopka
Detailed procedure
Vstavite preskusni primerek v kjeldahlovo bučko za razklop.
Transfer the specimen to a Kjeldahl digestion flask.
Preskusnemu primerku mase najmanj 1 g v bučki za razklop dodajte v naslednjem zaporedju: 2,5 g kalijevega sulfata, 0,1 do 0,2 g selenovega dioksida in 10 ml žveplove kisline (relativne gostote 1,84).
To the specimen weighing at least 1 g contained in the digestion flask, add, in the following order, 2,5 g potassium sulphate, 0,1 ‐ 0,2 g selenium dioxide and 10 ml sulphuric acid (relative density 1,84).
Segrejte bučko, sprva počasi, dokler se ne razkrojijo vsa vlakna, nato pa jo segrevajte močneje, dokler se raztopina ne zbistri in postane skoraj brezbarvna.
Heat the flask, gently at first, until the whole of the fibre is destroyed, and then heat it more vigorously until the solution becomes clear and almost colourless.
Segrevajte jo nadaljnjih 15 minut.
Heat it for a further 15 minutes.
Pustite bučko, da se ohladi, pazljivo razredčite vsebino z 10 do 20 ml vode, ohladite, kvantitativno prelijte vsebino v merilno bučko prostornine 200 ml in dolijte toliko vode, da dobite raztopino izvlečka.
Allow the flask to cool, dilute the contents carefully with 10 ‐ 20 ml water, cool, transfer the contents quantitatively to a 200 ml graduated flask and make up to volume with water to form the digest solution.
Nalijte približno 20 ml raztopine borove kisline v erlenmajerico prostornine 100 ml in podstavite erlenmajerico pod povratni hladilnik kjeldahlovega destilacijskega aparata tako, da dovajalna cev sega tik pod površino raztopine borove kisline.
Place about 20 ml of boric acid solution in a 100 ml conical flask and place the flask under the condenser of the Kjeldahl distillation apparatus so that the delivery tube dips just below the surface of the boric acid solution.
Vlijte natanko 10 ml raztopine izvlečka v destilacijsko bučko, dodajte najmanj 5 ml raztopine natrijevega hidroksida v lij, rahlo pridvignite zamašek in pustite, da raztopina natrijevega hidroksida počasi steče v bučko.
Transfer exactly 10 ml of digest solution to the distillation flask, add not less than 5 ml of sodium hydroxide solution to the funnel, lift the stopper slightly and allow the sodium hydroxide solution to run slowly into the flask.
Če raztopina izvlečka in raztopina natrijevega hidroksida ostaneta kot dve ločeni plasti, ju pomešajte z rahlim tresenjem.
If the digest solution and sodium hydroxide solution remain as two separate layers, mix them by gentle agitation.
Počasi segrejte destilacijsko bučko in vanjo uvajajte paro iz generatorja.
Heat the distillation flask gently and pass it into steam from the generator.
Zberite približno 20 ml destilata, spustite posodo za prestrezanje destilata tako, da je vrh dovajalne cevi kondenzatorja približno 20 mm nad površino tekočine in destilirajte še 1 minuto.
Collect about 20 ml of distillate, lower the conical flask so that the tip of the delivery tube of the condenser is about 20 mm above the surface of the liquid and distil for 1 minute more.
Sperite vrh dovajalne cevi z vodo, tako da izpiralno tekočino ujamete v posodo za prestrezanje destilata.
Rinse the tip of the delivery tube with water, catching the washings in the conical flask.
Umaknite posodo za prestrezanje destilata in namesto nje podstavite drugo, v kateri je približno 10 ml raztopine borove kisline ter ulovite vanjo okoli 10 ml destilata.
Remove the conical flask and replace it with another conical flask containing roughly 10 ml of boric acid solution and collect about 10 ml distillate.
Ločeno titrirajte oba destilata z žveplovo kislino 0,02N, uporabite mešani indikator.
Titrate the two distillates separately with 0,02N sulphuric acid, use the mixed indicator.
Zapišite celotno titracijsko vrednost vsakega destilata.
Record the total titre for the two distillates.
Če je titracijska vrednost drugega destilata večja od 0,2 ml, ponovite preskus in začnite destilirati nov odmerek nasičene raztopine.
If the titre for the second distillate is more than 0,2 ml, repeat the test and start the distillation again using a fresh aliquot of digest solution.
Izvedite slepi poskus, t.j. razkroj in destilacijo samo z uporabo reagentov.
Carry out a blank determination, i.e. digestion and distillation using the reagents only.
Izračunajte odstotek vsebnosti dušika v suhem preskusnem primerku na naslednji način:
Calculate the percentage nitrogen content in the dry specimen as follows:
A = odstotna vsebnost dušika v čistem, suhem preskusnem primerku,
A = percentage nitrogen in the clean dry specimen,
V = celotna poraba, standardne žveplove kisline v ml, uporabljene za določitev,
V = total volume in ml of standard sulphuric acid used in the determination,
b = celotna poraba standardne žveplove kisline v ml, uporabljene v slepem poskusu,
b = total volume in ml of standard sulphuric acid used in the blank determination,
N = normalnost standardne žveplove kisline,
N = normality of standard sulphuric acid,
W = suha masa (g) preskusnega primerka.
W = dry mass (g) of specimen.
Ob upoštevanju vrednosti 0,22 % za vsebnost dušika v juti in vrednosti 16,2 % za vsebnost dušika v živalskih vlaknih, pri čemer sta obe vsebnosti izraženi glede na suho maso vlaken, izračunajte sestavo mešanice na naslednji način:
Using the values of 0,22 % for the nitrogen content of jute and 16,2 % for the nitrogen content of animal fibre, both percentages being expressed on the dry mass of the fibre, calculate the composition of the mixture as follows:
PA % = odstotek živalskih vlaken v čistem, suhem preskusnem primerku.
PA % = percentage of animal fibre in the clean dry specimen.
