Nanocellulose for Wastewater Treatment
Summary
This review examines the potential of nanocellulose, a material derived from plant fibers, as an eco-friendly solution for removing contaminants from polluted water. Researchers found that nanocellulose's large surface area and ability to be chemically modified make it effective at capturing heavy metals, dyes, and other pollutants. The study suggests this renewable material could serve as a sustainable alternative to conventional water treatment methods.
Water pollution poses a serious threat, adversely affecting ecosystems and human health. Addressing this issue is essential to preserve water quality and protect vital resources. Implementing effective solutions is key to safeguarding ecosystems, promoting public health, and ensuring sustainable access to clean water for both present and future generations. The growing global concern over the contamination of natural resources, particularly freshwater, has heightened the demand for effective water treatment methods. There is growing interest in using renewable and eco-friendly reactive materials to support environmental sustainability and combat harmful contaminants. Among the various options, nanocellulose stands out as a promising candidate for environmental remediation due to its remarkable physicochemical properties. This chapter explores the intrinsic characteristics and structural features of different types of nanocellulose, including cellulose nanocrystals (CNCs), cellulose nanofibers (CNFs), and bacterial nanocellulose (BNCs). It has been extensively studied as an excellent biomaterial for wastewater treatment due to its outstanding properties including antifouling behavior, thermal resistance, large specific surface area, superior mechanical strength, high aspect ratio, biodegradability, and biocompatibility. Its extensive surface area is rich in free hydroxyl groups, which are easily modified and functionalized. This chapter also highlights recent advancements in nanocellulose applications, including heavy metal removal, oily water separation, and dye extraction, showcasing its potential as an effective adsorbent for improving filtration performance.
