Special Issue Information

Dear Colleagues,

The growing human activities in the field of mining, industry and intensive agricultural and livestock exploitation gave rise to increasing consumption of chemicals, pesticides and pharmaceutical products, which have become widely dispersed in the soil, watercourses and ground streams, with the risk of contaminating the environment and water for human consumption.

Monitoring water quality is becoming an important area of fundamental research and development of integrated systems. Sensors based on capillary electrophoresis, thin-layer chromatography, gas chromatography, fluorometric and colorimetric methods, ion chromatography, enzymatic methods, immunosensors, flow injection analysis and refractometric sensors have been around for a long time and, nonetheless, are constantly the object of dynamic and fruitful fundamental and applied research. Different monitoring techniques and modern monitoring devices and sensors allow researchers to get more in-depth information that could not be obtained before.

In this context, we invite you to submit manuscripts for the upcoming Special Issue dedicated to all aspects relevant to water quality monitoring. Full papers, communications, and reviews are welcome.

The purpose of this Special Issue is to collect advances in fundamental research and technology development, as well as innovative sensors for water monitoring, including different sensor platforms and configurations, sensing mechanisms and applications. Reviews must offer a critical overview of the state-of-the-art of fundamentals, technologies, and applications pertinent to water quality monitoring.

Potential topics include, but are not limited to, the following:

  • physical, chemical and biological sensors;
  • sensors based on chromatography, electrophoresis, colorimetry, enzymes and antibodies;
  • optical fiber sensors relying on evanescent waves, plasmonics and spectroscopy;
  • theoretical and simulation studies;
  • multiplexing of several physical and chemical parameters;
  • sensor networking and distributed sensing;
  • applications, such as agricultural, livestock, food processing and aquaculture activities, harsh environments or monitoring of water-intensive industries

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 submissions that pass pre-check are 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. Chemosensors is an international peer-reviewed open access monthly 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 2700 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.

Real-time measurements of carbonate ion concentrations in the ocean are critical to advancing marine environmental monitoring and research into deep-sea hydrothermal activity. Herein, we report the first example of deep-sea hydrothermal field exploration using a carbonate ion-selective electrode (ISE). The novel carbonate ISE was composed of a Ni wire as substrate, carbon film as transducers and carbonate-selective membrane layers. This paper describes the preparation process of the electrode and characterises its performance via scanning electron microscopy (SEM) and electrochemical analysis. The detection limit of the electrode for CO32− is 2.821 × 10−6 mol/L, the linear response range is 1.0 × 10−5–1.0 × 10−1 mol/L and the Nernst slope was −30.4 mV/decade. In April 2021, the carbonate ISE was mounted on multi-parameter sensors with pH and Eh (redox) electrodes for the search of hydrothermal activity at the Southwest Indian Ridge. The simultaneous potential anomalies appeared at this carbonate electrode with the pH and Eh electrodes when passing through the hydrothermal field. The study of the hydrothermal field was supported by the in situ camera video and the sulphide samples. Additionally, the carbonate electrode provides enhanced information of water chemistry for the study of the hydrothermal field. Full article
