چکیده
Bu çalışmada, Pd2+ iyonlarının iyodür (I-) ile PdI42- kompleksi oluşturarak, heksadesiltrimetilamonyum bromür (CTAB) yardımıyla kloroform fazına taşındığı ve spektrofotometre tayin edildiği bir mikroekstraksiyon yöntemi geliştirilmiştir. Ekstraksiyon verimliliğini etkileyen, pH, konsantrasyonu, potasyum hacmi yabancı iyon etkisi gibi deneysel parametreler optimize edilmiştir. Optimize edilen şartlarda paladyum için sınırı 19 µg L-1, bağıl standart sapma %2,1 zenginleştirme faktörü ise 10 olarak bulunmuştur. Geliştirilen metodun doğruluğu, gerçek numunelere ekleme/geri kazanım testleriyle belirlenmiştir. metot %94-106 geri değerleriyle, dere deniz suyu numunelerinde ekstraksiyonu tayini başarıyla uygulanmıştır.

Preconcentration and determination of palladium water samples by ionic liquid - dispersive liquid liquid microextraction combined with flame atomic absorption spectrometry
A simple, rapid and efficient dispersive liquid–liquid microextraction by use of ionic liquid (IL-DLLME)method, followed by flame atomic absorption spectrometry (FAAS) was developed for the preconcentrationand determination of palladium in water samples. In this method, an appropriate mixture of acetone and octylmethyl imidazolium hexafluorophosphate was injected rapidly into the aqueous sample...
متن کاملHCl- Etched Steel Fiber for Determination of Phthalates in Water Samples by Solid-Phase Microextraction
In the present work, a stainless steel wire was etched by hydrochloric acid during a chemical etching process. The obtained black layer on the surface of the fiber was used as sorbent for extraction of trace amount of phthalates in the aqueous samples by solid phase microextraction. New fiber efficiency was investigated using a home-made solid-phase microextraction (SPME) device and gas chr...
متن کاملSpectrophotometric Determination of Formaldehyde in Seawater Samples after In-situ Derivatization and Dispersive Liquid-Liquid Microextraction
In this paper, a simple dispersive liquid-liquid microextraction for the extraction and pre-concentration of formaldehyde in seawater samples followed with spectrophotometric is proposed. Formaldehyde was derivatized in situ with acetyl acetone in the presence of ammonium acetate in a single step. Then it was collected into a mixture of ethanol (disperser solvent) and chloroform (extracting...
متن کاملIonic Liquid Based Dispersive Liquid Liquid Microextraction and Enhanced Determination of the Palladium in Water, Soil and Vegetable Samples by FAAS
In this study, we combined Ionic Liquid-based Dispersive Liquid Liquid Micro Extraction (IL-DLLME) with FAAS for determining the palladium in different real samples at the trace level. 1-hexyl-3-methylimidazolium hexafluorophosphate [Hmim][PF6] ionic liquid and 1-(2-pyridylazo) 2-naphthol (PAN), were chosen as the extraction solvent and the chelating agent, respectively. The hydr...
