Special Issue Information

Dear Colleagues,

Addressing the global water crisis is a paramount challenge of the 21st century, with over 800 million people lacking access to safe drinking water due to contamination and scarcity. Urgent actions for water remediation are imperative. This Special Issue delves into developing eco-friendly, cost-effective materials to enhance the removal of regulated inorganic contaminants in water treatment processes. The proliferation of post-consumer and industrial waste underscores the need for sustainable solutions. Micropollutants, known for their high toxicity and resistance to degradation, pose significant risks to both humans and the environment. Traditional wastewater treatment methods often fail to eliminate these pollutants at low concentrations. This Special Issue explores novel treatment technologies to control and remove micropollutants from aquatic environments. Emphasizing the importance of energy-efficient approaches and environmental protection, this Special Issue highlights naturally derived adsorbents and their composites as promising materials. With attributes such as large surface area, porosity, and thermal stability, these materials show the potential in efficiently capturing pollutants. Recent research, uniting experimental and theoretical analyses, aims to deepen our understanding of mechanistic phenomena of adsorption. 

We welcome contributions that offer insights into the development of low-cost materials for removing micropollutants from water. The scope includes naturally derived polymers, biomass, synthetic polymers, polymer composites, and other relevant materials. Submissions integrating both theoretical and experimental aspects are encouraged, as well as those focusing exclusively on adsorption mechanisms.

This review embarks on a comprehensive journey, exploring the application of lignocellulosic biomass materials as highly effective adsorbents for the removal of textile dyes (cationic and anionic dyes) from wastewater. A literature review and analysis were conducted to identify existing gaps in previous research on the use of lignocellulosic biomass for dye removal. This study investigates the factors and challenges associated with dye removal methods and signifies their uses. The study delves into the pivotal role of several parameters influencing adsorption, such as contact time, pH, concentration, and temperature. It then critically examines the adsorption isotherms, unveiling the equilibrium relationship between adsorbent and dye and shedding light on the mechanisms of their interaction. The adsorption process kinetics are thoroughly investigated, and a detailed examination of the adsorbed rate of dye molecules onto lignocellulosic biomass materials is carried out. This includes a lively discussion of the pseudo-first, pseudo-second, and intra-particle diffusion models. The thermodynamic aspects of the adsorption process are also addressed, elucidating the feasibility and spontaneity of the removal process under various temperature conditions. The paper then dives into desorption studies, providing insights into the regeneration potential of lignocellulosic biomass materials for sustainable reusability. The environmental impact and cost-effectiveness of employing lignocellulosic biomass materials in textiles including Congo Red, Reactive Black 5, Direct Yellow 12, Crystal Violet, Malachite Green, Acid Yellow 99, and others dyes from wastewater treatment are discussed, emphasizing the significance of eco-friendly solutions. In summary, this review brings together a wealth of diverse studies and findings to present a comprehensive overview of lignocellulosic biomass materials as adsorbents for textile cationic and anionic dye removal, encompassing various aspects from influential parameters to kinetics, adsorption isotherms, desorption, and thermodynamics studies. Its scope and other considerations are also discussed along with its benefits. The collective knowledge synthesized in this paper is intended to contribute to the advancement of sustainable and efficient water treatment technologies in the textile industry. Full article
