Special Issue Information

Dear Colleagues,

With rapid urbanization and industrialization, the deterioration in water resources has emerged as a pressing global concern that requires urgent attention and effective solutions. The development and application of various advanced technologies in water purification have shown promising potential in improving water quality, which are crucial to establishing a safe and reliable water environment.

The advancement of scientific technology thrives on collaborations, sharing, and learning to overcome critical challenges together. Gathering the latest progress, challenges, and achievements is crucial to promoting the consolidation of knowledge and techniques in the field. The aim of this Special Issue is to bring together the innovative concepts, fruitful results, and valuable insights in the current development of advanced water purification techniques. Topics of this Special Issue include, but are not limited to, the following: advanced oxidation/reduction processes, catalytic processes, advanced adsorption processes, membrane technologies, electrocoagulation, and nanotechnology, including innonative adsorbent materials and pilot scaple applications. Contributions related to waste management and resource recovery/valorization in wastewater treatment processes are also encouraged. This Special Issue welcomes the submission of original research manuscripts and reviews.

Manganese (Mn) is widely used in many industries but is also biologically harmful when abundant in the environment. While there are several commercially available methods for manganese removal from water, efficient and cost-effective solutions for addressing manganese contamination in diverse environmental matrices remain limited. In this study, we developed a new method for removing Mn from contaminated lakes using an aptamer. The Seo-Gok Reservoir was selected as the study area due to its significant levels of Mn contamination. We first screened aptamers that bind to Mn through systematic evolution of ligands by exponential enrichment (SELEX). Among 6 aptamers (from FA-M1 to FA-M6), the FA-M1 aptamer exhibited the highest binding affinity to Mn with the lowest Kd value of 4.56 × 10−9 M. Potential Mn-binding sites in aptamers were predicted by analyzing the secondary structures. To confirm the binding of Mn to the proposed region, we evaluated the sequence homology of the screened aptamers. Aptamer specificity was evaluated against diverse metals. We demonstrated that FA-M1 could remove more than 95% of Mn from an aqueous sample; 99.9% of this Mn could then be recovered. FA-M1 removed more than 90% of Mn from a sample of the Mn-contaminated Seo-Gok Reservoir, indicating that aptamers can be utilized to remove Mn ions from the environment. Full article
