“…The determination of trace elements in seawater by direct analytical techniques is still a challenging task despite the availability of very sensitive analytical tools, such as the inductively coupled plasma mass spectrometry (ICP-MS), mainly due to seawater matrix interference and low concentration of trace elements [1,2].…”

A B S T R A C TThis work aims to study the use of a spiral supported liquid membrane (SLM) to extract lead (Pb) from seawater matrix using the di-(2-ethylhexyl) phosphoric acid (DEHPA) dissolved in kerosene as carrier. In this regard, several physical and chemical parameters which could affect Pb extraction (sample pH, sodium acetate buffer, HNO 3 concentration in stripping solution, masking agent effect, flow rate, filter porosity, and configuration of the SLM cell) were studied. In this sense, the permeability parameter was selected to probe the system efficiency. The optimal preconcentration factor was found to be of 14.2, after 2 h under the following conditions: sample pH equal to 4.7 buffered until a 0.08 M of sodium acetate, DEPHA concentration fixed at 0.21 M and HNO 3 concentration of 0.23 M in stripping solution. Besides, SLM filters were analyzed by electron microscopy after each period of 2 h and several microparticles and other deposits in form of a thin layer were observed in the polymeric support.

“…Concentrations of F in seawater and derived saline solutions were determined in two single IC runs, one for anions and another one for cations (Table 1) and the results so obtained were critically assessed in terms of anion-cation balance and further related to conductivity and salinity measurements aiming to evaluate the quality/completeness of ion chromatographic analyses and to search for other meaningful relations for efficient recognition/distinction between saline solutions of different types [17]. Typical chromatograms of the samples are in the original publication presented in Figure 3.…”

This review focuses on the ion chromatographic methods for the analyses of natural waters with high ionic strength. At the beginning a natural diversity in ionic composition of waters is highlighted and terminology clarified. In continuation a brief overview of other review articles of potential interest is given. A review of ion chromatographic methods is organized in four sections. The first section comprises articles focused on the determination of ionic composition of water samples as completely as possible. The sections-Selected Anions, Selected Cations and Metals-follow. The most essential experimental conditions used in different methods are summarized in tables for a rapid comparison. Techniques encountered in the reviewed articles comprise: direct determinations of ions in untreated samples with ion-or ion-exclusion chromatography, or electrostatic ion chromatography; matrix elimination with column-switching; pre-concentration with a chelation ion chromatography and purge-and-trap pre-concentration. Different detection methods were used: non-suppressed conductometric or suppressed conductometric, direct spectrometric or spectrometric after a post-column derivetization, and inductively coupled plasma in combination with optical emission or mass spectrometry.Keywords: ion chromatography; sea water; brine; mineral water; anions; cations; metals Natural Diversity of WatersWe restrict the scope of this review and choose to focus on natural waters with high ionic strength in which concentrations of ions extend over several orders of magnitude and therefore these waters present a special challenge for ion chromatographic (IC) analysis, especially if major and minor ions OPEN ACCESS
