“…In the CE determinations of inorganic ions, indirect ultraviolet–visible (UV‐Vis) absorption spectrometry is the most popular detection mode, but it suffers from the lack of sensitivity. Several publications have demonstrated the power of CE with indirect UV‐Vis detection for rapid and selective analysis of perchlorate in water samples, however, the achieved LODs ranged between 400 and 600 μg/L 28–30, which are not adequate for water monitoring according to the US EPA. In order to increase the detection sensitivity various detection techniques were applied to CE.…”

Electromembrane extraction (EME) and CE with capacitively coupled contactless conductivity detection (CE-C(4) D) was applied to rapid and sensitive determination of perchlorate in drinking water and environmental samples. Porous polypropylene hollow fiber impregnated with 1-heptanol acted as a supported liquid membrane (SLM) and perchlorate was transported and preconcentrated in the fiber lumen on application of electric field. High selectivity of perchlorate determination and its baseline separation from major inorganic anions was achieved in CE-C(4) D using background electrolyte solution consisting of 7.5 mM L-histidine and 40 mM acetic acid at pH 4.1. The analytical method showed excellent parameters in terms of reproducibility; RSD values for migration times and peak areas at a spiked concentration of 15 μg/L of perchlorate (US EPA recommended limit for drinking water) were below 0.2 and 8.7%, respectively, in all examined water samples. Linear calibration curves were obtained for perchlorate in the concentration range 1-100 μg/L (r(2) ≥0.999) with limits of detection at 1 μg/L for tap water and at 0.25-0.35 μg/L for environmental and bottled potable water samples. Recoveries at 15 μg/L of perchlorate were between 95.9 and 106.7% with minimum and maximum recovery values for snow and bottled potable water samples, respectively.

“…Figure 9 shows a representative set of electropherograms for metal ions differently associated with urban particulate matter, obtained after three-stage sequential extraction of a standard reference material. New procedures for determining common anions in drink- ing [180,181], rain [180], tap [47,55,98,115], mineral [47,55,98,115], river [55,98,142,180,182], groundwater [183], seawater [120,121,162,164,184], waste water [185], and soil extracts [186] or oxoanions in river water [187] were reported. Similar aquatic samples analyzed for alkali and alkaline earth metal ions encompass tap [188], rain [189], river [190], natural [191], underground water [192] and soil extracts [191,193], while transition metals were quantitatively characterized in mineral water [194], river water [133,190], and soil samples [193].…”

Capillary electrophoresis (CE) continues its invasion into the domain of inorganic analysis. This review summarizes the progress and significant developments of CE of inorganic ions over the first two years of the new century. As manifested by the substantial number of published articles, this field is still witnessing a growing activity of many separation scientists. To provide an in-depth treatment of fundamental and methodological aspects of inorganic ion analysis by CE, an extensive fraction of the relevant literature is covered whereas only most innovative application reports are briefly considered. Most of the recent advancements have focused on CE system modernization designed to improve a limited detection sensitivity, which still remains a major obstacle to overcome in order to ensure the method's wider practical acceptance. Attention is also given to how and in which directions the future research could be performed to implement CE in routine inorganic analysis.

“…Some recent applications are summarized in Table 1 [69,99,[142][143][144][145][146][147][148][149][150][151][152]. Determination of perchlorate in groundwater [143]; inorganic anions at trace levels in snow [144]; silicate with other nutrients in river water [145]; cationic and anionic species in cleanroom wipers [147], environmental water samples [148], and size-classified ice crystals [150]; inorganic anions in microbial fermentation [146]; trace metal cations in rain water [69]; and low molecular mass (LMW) mono-and dicarboxylic acids in airborne and vehicle-emitted samples [99,100,142] has been successfully performed and validated with the results obtained by other methods or using laboratory-made reference samples. For example, Dabek-Zlotorzynska et al [99] reported a reliable CE method with indirect UV detection for the determination of a large number of airborne and vehicle-emitted LMW organic acids.…”
