The present study aims at investigating the influence of the template ion/monomer proportion (1/4, 1/6, and 1/8) on sorbents properties. Polymers were packed in solid phase extraction (SPE) cartridges for characterization. A particular attention was paid to control the impact of this ratio on the retention of Ra(II) and interfering ions (<em>i.e.</em> specificity) on IIPs, their capacity, and their breakthrough volume. Although the IIPs 1/4 and 1/8 tended to be slightly more specific than IIP 1/6, the adsorption capacity of the IIP 1/4 was much lower (0.3 µmol g⁻¹) than the two others (3 µmol g⁻¹). Data modelling indicated that Sips and Redlich-Peterson models were best fitted, sign of a monolayer adsorption process into cavities not completely homogeneous in contrast to the Langmuir model. IIPs 1/6 and 1/8 showed both high breakthrough volumes (&gt;80 mL for 100 ng of Ba(II) percolated on 100 mg of sorbents) and BET experiments demonstrated no impact of the monomer proportion on surface area of the IIPs 1/4, 1/6, and 1/8. The repeatability of the synthesis was evaluated on the IIP 1/6. The SPE profiles resulting from three independent syntheses of the IIP 1/6 were very similar and thermogravimetric and BET analyses also confirmed that the three IIPs had similar physical characteristics. The IIP 1/6 was applied to the extraction of Ba(II) from spiked mineral waters (Mont Roucous® and Volvic®). The Ba(II) extraction recovery was subjected to matrix effects but those were solved by adapting the amount of sorbent to the volume of percolation solution. The optimized procedure has been successfully applied to extract ²²⁶Ra for the first time with a dedicated IIP in a real sample: 5 mL of Mont Roucous® water were spiked with 80 mBq L⁻¹ of ²²⁶Ra and ²²⁸Ra which was used as tracer to perform quantification by isotope dilution. After extraction, the ²²⁶Ra activity (88 ± 7 mBq L⁻¹, coverage factor k = 2) and recovery on IIP 1/6 (93%) were determined using an Inductively Coupled Plasma Mass Spectrometer and the limit of quantification of the method was estimated at 19 mBq L⁻¹ (0.52 pg L⁻¹).</p></div>","PeriodicalId":100052,"journal":{"name":"Advances in Sample Preparation","volume":"5 ","pages":"Article 100049"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49752121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two alternative analytical strategies for sample preparation employing diluted HNO₃ were optimized and compared, assisted by ultrasound (USAE) and infrared (IRAE) radiation.

For optimization of experimental conditions, a central composite design centered on the faces was carried out, considering four and five factors for IRAE and USAE, respectively. Dissolved organic carbon (DOC), residual acidity (RA) and solid residue (SR), significantly influence the responses to be evaluated. The response surface methodology was implemented to find the best combination of mass, diluted reagents (HNO₃ and H₂O₂), time and temperature in order to minimize responses for elemental extraction in animal feed samples. The optimized experimental conditions: 500 mg of sample mass, 60 °C of bath temperature, 30 min of extraction time, 2 mol L⁻¹ HNO₃ and 27% H₂O₂, were used to validate the USAE procedure. The conditions established for IRAE were 500 mg of the swine feed sample, followed by the addition of 2 mL of 2 mol L⁻¹ HNO₃ and 23% H₂O₂, irradiating for 23 min.

This study presents innovations to facilitate sample preparation at the point-of-need. First, the repeatability and reproducibility of two biopsy punch tools used to sample fish tissues (fillets) are assessed and compared. The first punch tool is commercially available (69039; Hatfield, PA) while the second was custom made. They were both simple to use and their results showed limited variability for mass collection. Second, a new, portable, low-energy-consumption ultrasonic probe for the rapid dissolution (&lt; 10 min) of fish tissues in tetramethyl ammonium hydroxide (TMAH) is presented. The dissolution rate, and Hg and Pb recovery rates in fish tissues are also reported and compared to those obtained with an ultrasonic bath. Finally, the analytical performances of both tools were validated on certified reference materials for mercury after analysis by GC-ICP-MS.

Important solvent properties to work as SLM were studied such as stability in the fiber and compatibility with HPLC. Then, the ability of the prepared NADES to extract 8 antibiotics of the family of sulfonamides (SAs) from water by HF-LPME was studied.

The optimized HF-LPME procedure was applied to the analysis of an artificial water containing humic acids, tap and river water samples, showing a good clean-up ability for all the tested samples. Calibration curves showed good linearity for all the SAs and samples with linear regression coefficients (r²) greater than 0.992.
