Effect of Plant Biomass Particle Size and PH on Dye Adsorption Efficiency

Abstract

Serious environmental concerns have been highlighted by the growing discharge of wastewater containing dyes from industrial and textile processes. Plant-based biomass adsorption has become a viable and economical color removal technique. The impact of plant biomass particle size and solution pH on dye adsorption efficiency is examined in this work. To assess removal efficiency, batch adsorption studies were carried out with different particle sizes and pH levels. The findings show that while pH plays a critical role in regulating the electrostatic interactions between adsorbent and dye molecules, smaller particle sizes greatly improve adsorption due to greater surface area. Depending on the type of dye, optimal adsorption was found in pH ranges from acidic to neutral. The results emphasize how crucial it is to optimize physicochemical parameters in order to increase biosorption effectiveness and support environmentally friendly wastewater treatment systems.
