Special Issue Information

Dear Colleagues,

Interest concerning ionic liquids in chemical analysis has grown considerably in the last decade, as evidenced by the large number of publications released every year. Their favourable properties, such as negligible vapour pressure, high thermal stability or unique solvating capability make ionic liquids suitable candidates to be used in numerous applications, especially in the fields of separation techniques. In addition, properties, such as viscosity or water solubility, can be tuned combining the associated anion and cation to modulate their utility. Further, the quest for new ionic liquids has led to the introduction of deep eutectic solvents, which are not exactly ionic liquids but a promising new class of solvents with similar properties. Deep eutectic solvents enable work with non-aqueous biphasic systems and show great promise in the separation of hydrophobic compounds.

All the continued research involving ionic liquids is continuously presented in books and Special Issues such as the one we are presenting here. This Special Issue invites contributions, as original research articles or reviews, on the current advances in and application of ionic liquids in separation techniques, especially focused on chromatography, extraction for sample preparation, or other related techniques.

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. Separations is an international peer-reviewed open access quarterly 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 350 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.

Abstract
In the over 1,800 articles published since their inception in 2001, most deep eutectic solvents (DES) synthesized have been hydrophilic. The low cost, low toxicity, and bioavailability of DES make the solvent ‘green’ and sustainable for diverse applications. Conversely, the hydrophilicity of DES [...] Read more.
In the over 1,800 articles published since their inception in 2001, most deep eutectic solvents (DES) synthesized have been hydrophilic. The low cost, low toxicity, and bioavailability of DES make the solvent ‘green’ and sustainable for diverse applications. Conversely, the hydrophilicity of DES limits their practical application to only polar compounds, which is a major drawback of the solvent. For the past three years, hydrophobic deep eutectic solvents (HDES) have emerged as an alternative extractive media capable of extracting non-polar organic and inorganic molecules from aqueous environments. Due to the infancy of HDES, for the first time, this mini-review summarizes the recent developmental advances in HDES synthesis, applications, challenges, and future perspectives of the solvent. In the future, it is believed HDES will replace the majority of toxic organic solvents used for analytical purposes. Full article
