Diclofenac (DCF) is a nonsteroidal anti-inflammatory drug to treat pain and inflammatory diseases. The high consumption of the drug leads to a significant change in the ecosystem. With the aim of optimizing a fast screening analysis for DCF detection on many samples with a sensitive and cheap procedure, we considered electrochemical methods using c...

Both inorganic and organic complexation of metal cations in clouds or rainwater is essential to describe the global biogeochemical cycles of metals, because complexation can increase metal solubility and stabilize some of their oxidation states. Within a Project of the National Research Program in the Antarctica, atmospheric depositions were collec...
Article
A method for direct (without chromatographic Rb/Sr separation) Sr isotopic analysis using tandem ICP-MS has been optimized for small-size environmental samples and applied to Antarctic PM 10 and soil samples from South America and Australia as proof-of-concept.

In this work, we present chemical stratigraphies of two sampling lines collected within a 4 m depth snow pit dug in Dome C during the Antarctic summer Campaign 2017/2018, 12 years after the last reported snow pit. The first sampling line was analyzed for nine anionic and cationic species using Ion Chromatography (IC); the second sampling line was a...
Article
A new procedure for the determination of Al, Ba, Ca, Fe, K, Mg, Na and Sr in snow samples by inductively coupled plasma optical emission spectrometry (ICP-OES) has been developed. The analytes were 100-fold preconcentrated by sample volume reduction and quantified by ICP-OES using the heated torch-integrated sample introduction system (hTISIS). Aft...

Lead content, enrichment factors, and isotopic composition (208Pb/206Pb and 207Pb/206Pb) measured in atmospheric particulate matter (PM10) samples collected for nine years at Ny-Ålesund (Svalbard islands, Norwegian Arctic) during spring and summer are presented and discussed. The possible source areas (PSA) for particulate inferred from Pb isotope...
Article
Lead (Pb) concentration and Pb isotope ratios have been determined in 109 snow pit samples collected at Dome C, on the East Antarctic Plateau, corresponding to the period 1971–2017. The Pb concentration was 8.2 ± 1.0 pg g⁻¹ (mean ± 95%-confidence interval), with a decreasing trend from the early 1990s (the median Pb concentration halved from 9.0 pg...

It is shown here that ZVI-Fenton is a suitable technique to achieve effective degradation of ibuprofen and phenol under several operational conditions. Degradation of ibuprofen was possible in the pH interval 3-6 in both synthetic laboratory systems and actual wastewater (secondary treatment effluent), but operation at the higher pH values required...
Article
Heterogeneous catalysts for the oxidation of toxic compounds are extremely important for many applications including environmental remediation. Here, we assessed the ability of Ti-substituted magnetite, i.e., titanomagnetite (Fe III(2-2x) Fe II(1+x) Ti x O 4 ) to promote Fenton-like heterogeneous reactions. Two titanomagnetites with x values respec...
Article
The complete removal of biorecalcitrant xenobiotics, including most notably the pharmaceutical pollutants, by advanced oxidation processes is often difficult to be reached in urban or industrial wastewater because of the high concentration of organic and inorganic scavengers that compete with the xenobiotics for the oxidizing species. This work inv...
Article
A method to assess the ability of a photocatalyst to induce reactions with free or trapped hydroxyl radicals versus direct charge-transfer processes is here proposed, based on the use of phenol and 2-hydroxybenzoic acid (salicylic acid) as test substrates. The rationale is that phenol degradation would be preferentially (although not exclusively) i...
