Review of preconcentration and solid phase extraction for the determination of trace Lead
Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. The use of an appropriate sample handling technique is a...

متن کاملDetermination 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 کاملAdsorption and Preconcentration of lead(II) by Solid-Phase Extraction Prior to Determination by Flame Atomic Absorption Spectrophotometry
A simple, reliable and rapid method for preconcentration and modification of silica gel with Isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate(IIDE) in order to prepare an effective sorbent for the preconcentration and determination of lead. The sorption capacity of Isopropyl 2[(isopropoxy carbothioyl)disulfanyl]ethanethioate(IIDE)-modified silica-gel (IIDE MS) was 82.34 mg.g -1 a...
