Special Issue Information

Dear Colleagues,

In recent decades, but especially in recent years, the rapid spread of toxic species has occurred in all matrices. Evidently, these contaminants, both of inorganic and organic origin, are very dangerous pollutants for human health, owing to their bioaccumulation and toxicity. They come from almost all human activities, such as, for example, industries, agriculture, vehicular traffic and urban heating.

Considering that, often, these species occur in various real matrices at extremely low concentrations, analytical methodologies must evidently show their possible application by verifying the correctness of all the steps: sampling, sample preparation, instrumental measurement and statistical data processing.

Another extremely important aspect concerns the fact that the development of new analytical methodologies, and the contemporary lack or inadequacy of regulations regarding the determination of toxic species in the most varied matrices, can obviously give to the legislator the possibility to update and improve the above-mentioned regulations.

This Special Issue aims to attract contributions on all aspects linked to the different analytical methods used for the determination of toxic species in the most varied matrices—food, environmental, forensic, biological, etc.—focusing particularly on the fundamental parameters of interest to set-up an analytical procedure, such as precision and trueness (that together give accuracy); the limits of detection and quantification; selectivity; and, especially, sensitivity.

This Special Issue is supported by the Sample Preparation Task Force and Network of the European Chemical Society Division of Analytical Chemistry (https://www.sampleprep.tuc.gr/en/home/).

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Multi-Walled Carbon Nanotubes Solid-Phase Extraction and Capillary Electrophoresis Methods for the Analysis of 4-Cyanophenol and 3-Nitrophenol in Water

Abstract
Analysis of 4-cyanophenol and 3-nitrophenol was carried out using multi-walled carbon nanotubes-based solid-phase extraction (SPE) and capillary electrophoresis (CE) methods. Capillary electrophoresis was carried out with 18 kV voltage, 214 nm detection, and phosphate buffer (pH 7.0, 15 mM) as background electrolyte at [...] Read more.
Analysis of 4-cyanophenol and 3-nitrophenol was carried out using multi-walled carbon nanotubes-based solid-phase extraction (SPE) and capillary electrophoresis (CE) methods. Capillary electrophoresis was carried out with 18 kV voltage, 214 nm detection, and phosphate buffer (pH 7.0, 15 mM) as background electrolyte at 25 ± 1 °C temperature with 15.05 and 16.5 min migration times of 4-cyanophenol and 3-nitrophenol. The separation and resolution factors were 1.10 and 2.90. The optimized experimental conditions were 40 mg/L concentration, 1.0 g multi-walled carbon nanotubes (MWCNTs) per SPE cartridge, 5.0 mL/min flow rate of water, 0.1 mL flow rate of eluting solvent. The maximum recoveries were 91% and 98% at 0.1 mL/min flow rate of 4-cyanophenol and 3-nitrophenol. These methods were applied successfully for extraction and estimation of 4-cyanophenol and 3-nitrophenol in the municipal wastewater. The reported methods are reproducible, efficient, and practical for the estimation of these phenols in water. Full article
