Special Issue Information

Dear Colleagues,

Growing environmental awareness and increasingly stringent regulations are driving the need for innovative and sustainable solutions in engineering. Green chemistry offers a promising approach to addressing environmental challenges by promoting processes and products that reduce or eliminate the use and generation of hazardous substances. Integrating green chemistry into environmental engineering not only enhances the sustainability of industrial processes but also contributes to environmental protection and human health.

This Special Issue aims to publish studies that explore the application of green chemistry in environmental engineering, focusing on emerging technologies and innovations that can have a significant impact. Topics of interest include, but are not limited to, the following:

  • Development of eco-friendly and biodegradable materials;
  • Green chemistry-based technologies for water and soil purification;
  • Synthesis and application of green catalysts;
  • Sustainable chemical processes for waste treatment;
  • Applications of green chemistry in pollution reduction and resource recovery;
  • Green solvents and reagents;
  • Life cycle assessment of green chemistry applications;
  • Renewable energy technologies incorporating green chemistry principles;
  • Advances in green chemistry for environmental remediation.

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. Applied Sciences 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 2400 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.

This study addresses the growing concern of water contamination by pharmaceutical residues, focusing on the simultaneous removal of paracetamol (PAR) and metronidazole (MTZ). Batch and fixed-bed column adsorption processes were evaluated using activated carbon. In the batch experiments, the effects of pH (3, 7, and 11), adsorbent mass (0.5, 1.25, and 2 g), and contact time (10, 30, and 60 min) were evaluated, while the fixed-bed column was optimized considering initial pollutants concentration (30, 40, and 50 mg/L), adsorbent mass (0.5, 0.75, and 1 g), and flow rate (5, 10, and 15 mL/min) to improve the maximum adsorption capacity of the bed for both pollutants (qmaxPAR and qmaxMTZ). Parameter estimation and model selection were performed using a Bayesian Monte Carlo approach. Optimal conditions in the batch system (pH = 7, W = 2 g, and time = 60 min) led to high removal efficiencies for both compounds (≥98%), while in the column system, the initial pollutant concentration was the most significant parameter to improve the maximum adsorption capacity of the bed, resulting in values equal to 49.5 and 43.6 mg/g for PAR and MTZ, respectively. The multicomponent Gompertz model showed the best performance for representing the breakthrough curves and is suitable for scale-up (R2 ≥ 0.75). These findings highlight the complexity of multicomponent adsorption and provide insights, contributing to the development of more efficient and sustainable water treatment technologies for pharmaceutical residues.
