Carbon-based filtration technologies have emerged as a pivotal solution for purifying water sources from a myriad of hazardous contaminants. Recent studies have delved deeply into the adsorptive capabilities of these systems, revealing their high efficiency against emerging pollutants such as pharmaceutical items, personal care products, and industrial chemicals. Results from these investigations highlight the significant roles both the physical properties of carbon and the chemical nature of the water play in determining the effectiveness of contaminant removal. Despite these advancements, gaps remain in understanding the long-term efficiency and lifespan of carbon-based filters, especially concerning newer and lesser-known contaminants.

This Research Topic aims to expand our understanding and enhance the functionality of carbon nanomaterial-based water filtration systems, particularly in removing emergent contaminants. Key objectives include examining the advancements in carbon adsorption technologies, assessing the influence of material characteristics and water chemistry on filtration effectiveness, and exploring how to boost environmental sustainability through improved water purification practices. Ultimately, the goal is to refine these technologies for better protection of aquatic ecosystems and contribute to sustainable water resource management.
