Special Issue Information

Dear Colleagues,

The global shortage of potable water as well as the incremental contamination of fresh water was, is, and will be a prominent social and environmental problem that demands to be urgently faced. The ubiquitous widespread of hazardous contaminants in water systems, such as personal care products, pesticides, pharmaceuticals, and especially antibiotics, per-and-poly-fluoroalkyl substances (PFASs), and dyes, among others, is resulting in the depletion of water resources and deterioration of the aquatic ecosystem. At present, several treatment technologies have been implemented to remove pollutants from impacted water matrixes, including biodegradation, membrane filtration, chemical precipitation, and advanced oxidation processes (AOPs). However, these methods have advantages as well as drawbacks regarding process efficiency, operation costs, feasibility, and environmental impacts. Among them, adsorption technology has gained more attention as an effective desirable separation process because of its simplicity, low cost, high treatment efficiency, and applicability to various conditions. To overcome the limitations of traditional adsorbents, the development, preparation, and synthesis of novel (nano)materials capable of being utilized as adsorbents are strongly required. 

This Special Issue welcomes original research papers, review articles and case studies focused on the preparation, synthesis, and application of novel adsorbents for removing organic pollutants from water and wastewater. Thermodynamics and kinetic assessments of the adsorption process are suggested, as well as desorption and regeneration of the adsorbents. Cost estimation of the adsorbents and in general of the entire water treatment process as well as life-cycle assessment (LCAs) analysis are highly encouraged. The main goal is to provide a platform for the “Molecules” scientific community by highlighting the recent advances and further developments of the adsorption method".

The long-term presence of PPCPs in the aqueous environment poses a potentially significant threat to human life and physical health and the safety of the water environment. In our previous work, we investigated low-cost pitch-based HCP adsorbents with an excellent adsorption capacity and magnetic responsiveness through a simple one-step Friedel–Crafts reaction. In this work, we further investigated the adsorption behavior of the prepared pitch-based adsorbents onto three PPCP molecules (DFS, AMP, and antipyrine) in detail. The maximum adsorption capacity of P-MPHCP for DFS was 444.93 mg g−1. The adsorption equilibrium and kinetic processes were well described through the Langmuir model and the proposed secondary kinetic model. The negative changes in Gibbs free energy and enthalpy reflected that the adsorption of HCPs onto PPCPs was a spontaneous exothermic process. The recoverability results showed that the adsorption of MPHCP and P-MPHCP onto DFS remained above 95% after 10 adsorption–desorption cycles. The present work further demonstrates that these pitch-based adsorbents can be used for multiple applications, which have a very extensive practical application prospect. Full article
