This study investigates the use of starch nanocrystals as adsorbent materials in continuous fixed-bed column systems for removing cationic dyes from wastewater. The researchers developed mathematical models to predict breakthrough curves and understand competitive adsorption behavior when multiple dyes are present simultaneously in the system. The work demonstrates that starch nanocrystals can effectively capture cationic dyes in flow-through conditions and provides predictive tools for designing industrial-scale water treatment processes.


This research offers a sustainable, bio-based alternative to conventional adsorbents for textile and industrial wastewater treatment. The breakthrough modeling framework enables engineers to predict system performance with mixed contaminants, which is critical for real-world applications where multiple pollutants coexist.
