Special Issue Information

Dear Colleagues,

As is widely understood, water is essential for life on Earth and plays an important role in the maintenance and functioning of communities, the economy and society. However, modern consumer society endangers global water resources on a daily basis via the emission of various harmful substances into the environment. Moreover, due to increasingly pronounced climate changes, the lack of drinking water is becoming more noticeable. Therefore, in order to preserve the excellent quality of water in nature, but also to ensure a sufficient amount of water for human, industrial, and agrarian consumption, it is necessary to invest enormous effort and resources into the development of effective methods of wastewater treatment. In addition, giving value to once-used water is essential from both an economic point of view and for the preservation of natural resources. Thus, the development of new materials and technologies in wastewater treatment is a key challenge today.

This Special Issue aims to collect original high-quality articles that explore the full potential of new materials for applications in environmental protection and water and wastewater treatment. Research areas include (but are not limited to) the following topics: membranes, development of novel materials, material structural design and optimization, new technologies, pollutants removal mechanisms, process modelling and simulation, and practical (industrial) applications. The highest level of emphasis is given to the materials for membrane construction. However, we are also interested in methods and technologies engaged in water and wastewater treatment. For instance, adsorption, ion exchange, etc., are very welcome topics.

We are pleased to invite you to submit your latest research results. Both original research articles and reviews with new insights in the abovementioned topics are welcome.

Please do not hesitate to make contact with us if you require additional information.

We are looking forward to your contributions.

You may choose our Joint Special Issue in Membranes.

Three-dimensional hierarchical porous carbons (HPCs) created through hydrothermal carbonization and the subsequent chemical activation of miscanthus were tested as adsorbents of Pb2+ and methylene blue from the aqueous solution. The HPC pore structure was customized using various hydrochar precursors obtained through a longer reaction time and by adding acetic acid. HPC obtained from hydrochar derived from acetic acid’s addition exhibited the highest specific surface area due to a larger micropore volume. This adsorbent proved to be the most efficient in removing lead from aqueous solutions. The Langmuir isotherm best described the lead adsorption process onto HPC with qm = 155.6 mg g−1 and the pseudo-second-order kinetic model. HPC obtained from hydrochar produced with a longer reaction time exhibited improved methylene blue adsorption properties. The pseudo-second-order kinetic model and the Freundlich isotherm best described the experimental data. The theoretical maximum adsorption capacity for methylene blue was 316.0 mg g−1. The type of hydrochar significantly impacted the yield and physical structure of HPCs, while having a lesser effect on the composition of surface functional groups. The results revealed the binding mechanism of each pollutant, highlighting the importance of biomass pretreatment on the structure of the resulting HPC and its effectiveness in water purification.

This paper presents the results of the application of hazardous waste slag generated by lignite combustion for the adsorption of ethyl xanthate anions (EX) from aqueous solutions. The starting material (RWS) was washed (WWS) and modified (MWS) and then characterized in detail by using different chemical and physical–chemical techniques (determination of chemical composition and content of heavy metals, X-ray diffraction (XRD), infrared spectroscopy (FTIR), determination of textural properties and point of zero charge). Besides the chemical stability of EX, the influence of the initial pH, mass of the adsorbent, initial concentration, and time on the EX anion removal was tested. The characterization results showed that applied waste slag is a hazardous material with complex mineral and structural properties but with good buffer properties and pH stability, which is also characteristic of the MWS sample. The adsorption experiments showed that modification with Cu(NO3)2 and Fe(NO3)3 significantly increases the adsorption capacity of the starting slag. Under applied experimental conditions, the maximal adsorbed amount of EX anions on the MWS was 210 mg/g, while equilibrium was obtained after 700 min. The Freundlich model and pseudo-second-order model best fit the results, suggesting the complex mechanism of EX removal by the MWS sample. Full article
