If different protein fibres are present, the method gives the total of their amounts but not their individual quantities.
Če so prisotna različna proteinska vlakna, se z metodo določi njihova skupna količina, ne pa količina posameznih vrst vlaken.
The protein fibre is dissolved out from a known dry mass of the mixture, with a hypochlorite solution.
Proteinsko vlakno se iz mešanice znane suhe mase odtopi z raztopino hipoklorita.
The percentage of dry protein fibre is found by difference.
Odstotek suhih proteinskih vlaken se izračuna iz razlike.
Either lithium hypochlorite or sodium hypochlorite can be used for the preparation of the hypochlorite solution.
Za pripravo raztopine hipoklorita se lahko uporabi litijev hipoklorit ali natrijev hipoklorit.
Lithium hypochlorite is recommended in cases involving a small number of analyses or for analyses conducted at fairly lengthy intervals.
Litijev hipoklorit je priporočljiv v primerih, kjer gre za manjše število analiz ali za analize, ki se izvajajo v daljših presledkih.
This is because the percentage of hypochlorite in solid lithium hypochlorite — unlike that in sodium hypochlorite — is virtually constant.
Razlog za to je, da je odstotek hipoklorita v trdnem litijevem hipokloritu – v nasprotju z natrijevim hipokloritom – skoraj konstanten.
If the percentage of hypochlorite is known, hypochlorite content need not be checked iodometrically for each analysis, since a constant weighed portion of lithium hypochlorite can be employed.
Če je odstotek hipoklorita znan, vsebnosti hipoklorita ni potrebno določati jodometrično za vsako analizo posebej, saj se lahko uporabi konstantni utežni % litijevega hipoklorita.
Erlenmeyer flask with ground-glass stopper, 250 ml.
Erlenmajerica z brušenim steklenim zamaškom in prostornino 250 ml.
Thermostat, adjustable to 20 ± 2 °C.

Hipokloritni reagent
Lithium hypochlorite solution
Raztopina litijevega hipoklorita
This consists of a freshly prepared solution containing 35 ± 2 g/l of active chlorine (approximately 1 M), to which 5 ± 0,5 g/l of previously dissolved sodium hydroxide is added.
Raztopina sestoji iz sveže pripravljene raztopine, ki vsebuje 35 ± 2 g/l aktivnega klora (približno 1 M), ki ji je dodano 5 ± 0,5 g/l predhodno raztopljenega natrijevega hidroksida.
To prepare, dissolve 100 grams of lithium hypochlorite containing 35 % active chlorine (or 115 grams containing 30 % active chlorine) in approximately 700 ml of distilled water, add 5 grams of sodium hydroxide dissolved in approximately 200 ml of distilled water and make up to 1 litre with distilled water.
Za pripravo raztopite 100 gramov litijevega hipoklorita, ki vsebuje 35 % aktivnega klora (ali 115 gramov, ki vsebuje 30 % aktivnega klora) v približno 700 ml destilirane vode, se doda 5 gramov natrijevega hidroksida, raztopljenega v približno 200 ml destilirane vode; nato se dolije destilirana voda do skupno 1 litra.
The solution which has been freshly prepared need not be checked iodometrically.
Sveže pripravljene raztopine ni potrebno preverjati z jodometrijo.
Sodium hypochlorite solution
Raztopina natrijevega hipoklorita
This consists of a freshly prepared solution containing 35 ± 2 g/l of active chlorine (approximately 1 M) to which 5 ± 0,5 g/l of previously dissolved sodium hydroxide is added.
Raztopina sestoji iz sveže pripravljene raztopine, ki vsebuje 35 ± 2 g/l aktivnega klora (približno 1 M) in ki ji je dodano 5 ± 0,5 g/l predhodno raztopljenega natrijevega hidroksida.
Check the active chlorine content of the solution iodometrically before each analysis.
Pred vsako analizo je treba jodometrično preveriti vsebnost aktivnega klora.
Acetic acid, dilute solution
Ocetna kislina, razredčena raztopina
Dilute 5 ml of glacial acetic acid to 1 litre with water.
5 ml ledocetne kisline se razredči do 1 litra z vodo.
Follow the procedure described in the general instructions and proceed as follows: mix approximately 1 gram of the test specimen with approximately 100 ml of the hypochlorite solution (lithium or sodium hypochlorite) in the 250 ml flask and agitate thoroughly in order to wet out the test specimen.
Izvede se postopek, opisan v splošnih navodilih, in nadaljuje, kot sledi: v erlenmajerici s prostornino 250 ml se 1 gram preskusnega primerka prelije s približno 100 ml raztopine hipoklorita (litijevega ali natrijevega hipoklorita) in temeljito pretrese, da se preskusni primerek omoči z raztopino.
Then heat the flask for 40 minutes in a thermostat at 20 °C and agitate continuously, or at least at regular intervals.
Erlenmajerica z vsebino se namesti v termostat za 40 minut pri temperaturi 20 °C, pri čemer se jo ves čas ali vsaj v rednih časovnih presledkih pretrese.
Since the dissolution of the wool proceeds exothermically, the reaction heat of this method must be distributed and removed.
Ker je raztapljanje volne eksotermen proces, je treba reakcijsko toploto pri tej metodi porazdeliti in odvajati.
Otherwise, considerable errors may be caused by the incipient dissolution of the non-soluble fibres.
V nasprotnem primeru lahko pride do precejšnih napak zaradi začetka raztapljanja netopnih vlaken.
After 40 minutes, filter the flask contents through a weighed glass-filter crucible and transfer any residual fibres into the filter crucible by rinsing the flask with a little hypochlorite reagent.
Po 40 minutah se vsebina erlenmajerice prefiltrira skozi predhodno stehtan stekleni filtrirni lonček in vsa preostala vlakna prenesejo v filtrirni lonček, tako da se erlenmajerica izpere z manjšo količino hipokloritnega reagenta.
Do not apply suction until each washing liquor has drained under gravity.
Med samim izpiranjem ali med posameznimi izpiranji se tekočina ne odsesava, temveč naj najprej odteče zaradi težnosti in šele nato odsesa.
Finally, drain the crucible with suction, dry the crucible with the residue, and cool and weigh them.
Na koncu se tekočina odsesa iz filtrirnega lončka, filtrirni lonček z vsebino pa posuši, ohladi in stehta.
