Special Issue Information

Dear Colleagues,

The development of industry, constant urbanization, and an increasingly consumptive lifestyle, contribute to increasing the emission of gaseous and liquid pollutants and generating huge amounts of solid waste. The former poses a very serious threat to the atmosphere, surface and ground waters, and soil. Solid waste, on the other hand, is a problem because it requires landfilling, which is associated with the constant increase in the landfill area. For this reason, increasing attention is being paid to the development of all kinds of solutions to effectively reduce the amount of waste going to landfills. One of the ways to dispose of industrial and post-agricultural waste is currently their reuse. The materials obtained in this way can be successfully used in many branches of modern industry, as well as in environmental protection, among others, for the purification of waste gases and post-production wastewater, or for the remediation of contaminated soil. At the same time, energy-saving activities have been a key aspect recently. In this context, a new approach to environmental protection issues has been so-called "green chemistry", the principles of which are guidelines for reducing the consumption of raw materials and energy, reducing waste and generally reducing production costs. The idea is to eliminate processes that generate environmentally harmful organic substances, as well as to save reagents and energy. An excellent alternative to this type of solution is the production of waste materials from the biomass industry (pine cones), agriculture (wheat bran, straw) and in the household (coffee, tea grounds) to obtain valuable carbon adsorbents the perspective of their use in cleaning processes water from various types of pollutants, using adsorption and photocatalytic processes.

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. Materials 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 2600 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.

PFASs are a variety of ecologically persistent compounds of anthropogenic origin loosely included in many industrial products. In these, the carbon chain can be fully (perfluoroalkyl substances) or partially (polyfluoroalkyl substances) fluorinated. Their ubiquitous presence in many environmental compartments over the years and their long-lasting nature have given rise to concerns about the possible adverse effects of PFASs on ecosystems and human health. Among a number of remediation technologies, adsorption has been demonstrated to be a manageable and cost-effective method for the removal of PFASs in aqueous media. This study tested two novel and eco-friendly adsorbents (pinewood and date seeds biochar) on six different PFASs (PFOS, GenX, PFHxA, PFOA, PFDA, and PFTeDA). Batch sorption tests (24 h) were carried out to evaluate the removal efficiency of each PFAS substance in relation to the two biochars. All samples of liquid phase were analyzed by a developed and then a well-established method: (i) pre-treatment (centrifugation and filtration) and (ii) determination by high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS). The results evidenced a comparable adsorption capacity in both materials but greater in the long-chain PFASs. Such findings may lead to a promising path towards the use of waste-origin materials in the PFAS remediation field. Full article
