Abstract:Sproščanje formaldehida iz vrhunsko apretiranega materiala je za zdravje in varnost ljudi škodljivo zaradi morebitne kancerogenosti formaldehida. Natančnost standardne testne metode za določanje prostega formaldehida, Japan Law 112 je odvisna od vsebnosti formaldehida v vzorcu. Vsebnosti formaldehida pod 20 ▫$\mu$▫\g s to metodo ne moremo določiti. Zaznavanje nizkih vsebnosti formaldehida je pomembna predvsem na nekaterih področjih, kot so otroška oblačila, kjer bi lahko uporabili tekočinsko kromatografijo. Tekstilne substrate, obdelane z različnimi reagenti za zamreženje, smo ekstrahirali z vodo in prosti formaldehid določili z acetilacetonsko metodo. Rezultate, dobljene s standardno testno metodo, Japan Law 112, kjer smo uporabili UV/VIS spektrofotometer, smo primerjali z rezultati, dobljenimi s HPLC, kjer je separacija potekala na RP C 18 koloni in z vodo : $MeOH$ kot mobilno fazo. Meja detekcije in meja kvantitativne določitve je boljša z uporabo HPLC metode. Koncentracijsko območje pri HPLC metodi je od 0.3 ▫$\mu$▫g do 30 ▫$\mu$▫/g.

Title:Determination of free formaldehyde on cotton textile substrates by using HPLC
Abstract:Release of formaldehyde from durable press treated fabrics is a problem for human health and safety because formaldehyde is suspected to be carcinogen. The accuracy of the standard test method for the free formaldehyde determination, Japan Law 112, depends on the formaldehyde content of the sample. The formaldehyde contents below 20 ▫$\mu$▫\g can not be shown to be caused by formaldehyde. The detection of low formaldehyde contents is important particularly in some fields, like children clothing, so the high performance liquid chromatography was used. With different crosslinking reagents finished textile substrates were extracted with water to detect the free formaldehyde by an acetylacetone method. The results obtained by the standard test method, Japan Law 112, where UV/Vis spectrometer was used, were compared with the results obtained by HPLC method where separation was performed on RP C 18 column with water/$MeOH$ as a mobile phase. It was shown that the detection limit and limit of quantification were improved using HPLC method. Concentration range obtained by HPLC method is from 0.3 ▫$\mu$▫g to 30 ▫$\mu$▫/g.
