Background: the supplementation of natural antioxidants such plant flavonoids may counteract the deleterious actions of gamma-irradiation and iron overload. Material and Methods: the protective effect of naringin (NIN) against kidney injury induced by γ-irradiation (IRR) (6.5 Gy) and/or iron dextran (ID) (50 mg/kg. b. w) has been studied in rats given 80 mg/kg b.w of NIN for 14 days before, and...

Solvent sublation has been studied for the separation and determination of trace iron(II) in various kinds of water samples. A strongly magenta-colored anionic [Fe(FZ)3](4-) complex was formed at pH 5.0 upon adding 3-(2-pyridyl)-5,6-bis(4-phenylsulfonic acid)-1,2,4-triazine (ferrozine, FZ) to the sample solution. Tetrabutylammonium bromide (TBAB) was added in the solution to form the (TBA)4[Fe(...

An RP-HPLC method for the separation and determination of aluminium(III), vanadium(V), iron(III), copper(II) and nickel(II) with CALKS (Chromazol KS) and PAR ([4-(2-pyridylazo)resorcinol]) chelating on a YWG-ODS column was developed. A mixture of methanol-tetrahydrofuran(THF)-water (60:5:35 v/v) containing 0.2 mol/L LiCl, 5 x 10(-5) mol/L CALKS, 5 x 10(-5) mol/L PAR and acetate buffer solution ...

Uranium and some other trace elements were determined in the size-separated airborne dust collected in Tsukuba with an Andersen-type high-volume cascade impactor. The fission track method and the instrumental neutron activation method were applied to the determination of uranium and other elements, respectively. Selenium, antimony, arsenic and zinc were found to be rich in particulates of small...

In this work, an simple and fast method based solid phase extraction for preconcentration and separation of trace amount of Fe(III) ions from water samples prior to its determination by flame atomic absorption spectrometry (FAAS) was developed. The silver nanoparticles coated silica gel was modified by morin and then it was used as a adsorbent. The silver nanoparticle coated silica gel was prep...
