dc.description.abstract | Recoveries of solid phase disk extraction and supercritical fluid extraction of natural groundwater samples were compared in this study. Deionised water sample (1 dm3) was spiked with a mix of lindan (g-HCH) and its metabolites (a-HCH, b-HCH, d-HCH) at level of 2.25 ng l-1 of each component. Extraction of spiked groundwater was performed by C-18 solid phase disks. Captured analytes were eluted from the disk in two different ways: 1) eluate obtained by the use of a solvent was evaporated to dryness and then again dissolved in acetone and 2) elution with supercritical fluid (CO2). Extracts were analysed by GC-ECD and an internal standard. Recoveries of extracts achieved with supercritical elution were much better than those with classical elution with a solvent. | en |
dc.description.abstract | U ovom radu su upoređeni prinosi čvrsto fazne ekstrakcije i superkritične ekstrakcije pesticida iz vode. U 1 dm3 dejonizovane vode dodata je mešavina lindana i njegovih metabolita u koncentraciji od 2,25 ng/dm3 za svaki analit. Ekstrakcija vode je izvedena upotrebom C-18 ekstrakcionih diskova. Analiti su sa diska eluirani na dva načina: 1) eluat dobijen upotrebom rastvarača uparen je do suva i ponovo rastvoren u acetonu, i 2) elucija sa superkritičnim fluidom (CO2). Dobijeni ekstrakti su analizirani upotrebom GC-ECD i internog standarda. Prinosi dobijeni superkritičnom ekstrakcijom su značajno viši od prinosa dobijenih eluiranjem analita pomoću rastvarača. | sr |
