Determination of Rubidium in Seawater
نویسندگان
چکیده
Rubidium concentrations in seawater from various locations and depths to 3,900 m have been determined using two independent techniques--direct flame photometry and mass spectrometry. Results of these two techniques agree within estimated errors and indicate that the rubidium content in the oceans is uniform within H$% with values varying about 120 pg/liter. Sediment from the sea floor below a depth profile, analyzed for rubidium and potassium, gave a rubidium concentration factor of 150 and a potassimil to rubidium ratio of 1,270.

Determination of Some Polycyclic Aromatic Hydrocarbons in the Caspian Seawater by HPLC Following Preconcentration with Solid-Phase Extraction
A solid-phase extraction (SPE) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (RP-HPLC) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (PAHs) in the caspian seawater. A good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. The eff...
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 کاملOptimizing of microfunnel-supported liquid-phase microextraction for the extraction of chlorophenoxyacetic acids in seawater samples
Abstract In this study, microfunnel-supported liquid-phase microextraction method (MF-LPME) was optimized and applied for the determination of some chlorophenoxyacetic acids (CPAAs) from natural water samples. The extraction was performed with 540 μL toluene which was retained at the surface of the sample solution using an upside down microfunnel. After the extraction, toluene was moved in...
