“…Classical C18 [23,58,79] and polymeric PS-DVB [54,73] . When compounds with acidic properties (e.g., benzophenone-4 (BZ4) and phenylbenzymidazole sulfonic acid (PBS)) are also pursued, PVP-DVB/MCX shows better performance compared to PVP-DVB [28,70], since the non-acidic compounds are well retained in the PVP-DVB skeleton, whereas the acidic ones prefer the modified moieties.…”

Personal-care products (PCPs) could reach the aquatic environment and cause a great impact in the aquatic ecosystem. In this sense, the monitoring of these emerging pollutants in the environment yields valuable information. For this reason, analytical methods to determine PCPs in environmental waters are needed. Due to the low concentration of the PCPs, i.e. ng L À1 , sensitive methods are needed. This required sensitivity can be achieved by using sensitive analytical techniques during the measurement step, or by employing enrichment techniques during the sample treatment step. Obviously, the combination of both sensitive analytical techniques and extraction techniques considerably improves the quality of the determination.In this way, in the last years, different analytical methods have been developed to determine PCPs in environmental waters from different origin, i.e., water from sea, lake, river, influent and/or effluent wastewater treatment plant, swimming pool, tap, and groundwater. The aim of this chapter is to compile and discuss the analytical literature dealing with the development and validation of analytical methods for determining PCPs in environmental water samples, emphasizing both the employed sample treatment and the subsequent analytical technique.

“…In in‐line SPE‐CE, an analyte concentrator is synthesized or placed as a short column near the inlet end of the CE capillary . To do so, different set‐ups have been reported in the literature, of which the most commonly used is the system based on the use of small packed beads, with the most widely employed sorbents being Oasis HLB, Oasis MCX, and C 18 . In this configuration, the SPE material can be retained by means of two frits but, over time, their use has become less advisable due to issues with performance arising from several disadvantages discussed elsewhere .…”

A simple approach is presented based on the in-line coupling between magnetic particles-based SPE and CE. Silica-coated iron oxide particles functionalized with C18 were successfully synthesized and used as a reverse-phase sorbent for in-line SPE-CE. Magnets were used to locally immobilize these sorbents inside the capillary. Four drugs of abuse were preconcentrated and determined in urine samples using the developed method with a simple pretreatment procedure based on LLE. Several parameters affecting the preconcentration were evaluated. The obtained results show that this strategy enhanced detection sensitivity in the range of 125-700-fold compared with CE without preconcentration. The developed method provides LODs (S/N = 3) for standard samples in the range of 0.5-20 ng/mL with satisfactory analytical precision, in both intraday and day-to-day experiments (RSDs <20%). The LODs (S/N = 3) reached for urine samples were in the range of 20-50 ng/mL. Relative recoveries greater than 75.9% were obtained. The established method has been applied to the analysis of drugs of abuse in urine samples from drug abusers.

UV filters, contained in sunscreens and other cosmetic products, as well as in some plastics and industrial products, are nowadays considered contaminants of emerging concern because their widespread and increasing use has lead to their presence in the environment. Furthermore, some UV filters are suspected to have endocrine disruption activity. In the present work, we developed an analytical method based on liquid chromatography with tandem mass spectrometry for the determination of UV filters in tap and lake waters. Sixteen UV filters were extracted from water samples by solid-phase extraction employing graphitized carbon black as adsorbent material. Handling 200 mL of water sample, satisfactory recoveries were obtained for almost all the analytes. The limits of detection and quantification of the method were comparable to those reported in other works, and ranged between 0.7-3.5 and 1.9-11.8 ng/L, respectively; however in our case the number of investigated compounds was larger. The major encountered problem in method development was to identify the background contamination sources and reduce their contribution. UV filters were not detected in tap water samples, whereas the analyses conducted on samples collected from three different lakes showed that the swimming areas are most subject to UV filter contamination.
