Studies for Sorption of Aniline Blue Dye Using Eucalyptus Leaves Powder and Optimization Using Central Composite Design

Abstract

In this study, a novel biosorbent called Eucalyptus leaves powder is used in a batch biosorption process to remove the Aniline blue from aqueous solutions. Agitation time, biosorbent size, pH, initial dye concentration, biosorbent dosage, and temperature are among the characteristics that were examined. Lagergren first order and pseudo second order models were included in the kinetic investigation. The study also covered isotherms such as Temkin, Freundlich, and Langmuir as well as thermodynamics. Regression analysis revealed that the experimental data was highly well-fitting and correlated.
