Summary: Through the study, it was found that the activation energy for biomass samples varied significantly in different conversion ranges, and the frequency factor values also varied within the same conversion ranges for different samples. The average change in Gibbs free energy for the pyrolysis of pinewood sawdust and sugarcane bagasse was 207.5 and 205.8 kJ/mol, respectively. The difference between activation energy and enthalpy for the pyrolysis of both biomass samples was approximately 5.5 kJ/mol, indicating favorable product formation with considerable bioenergy potential.

Summary: The study demonstrates that eucalyptus sawdust can serve as an alternative biomaterial for adsorbing lead (II) in wastewater, with optimal adsorption occurring at a pH of 6, achieving a removal percentage of 96% and an adsorption capacity of 4.80 mg/g. The main mechanism of bioadsorption is found to be chemisorption, primarily supported by ion exchange between Pb(II) ions and functional groups of the biomass.

Summary: This study explores the use of extractives-free SCB as a renewable adsorbent to remove Rhodamine B from water, contributing to environmental conservation and better utilization of natural resources. The adsorption kinetics and equilibrium uptake were assessed under different pH, RhB concentrations, and temperatures. The results show that the Elovich and multi-mechanistic models best describe the adsorption kinetics, and the adsorption is primarily physisorption but may involve chemisorption. The study also reports on the regeneration and reuse of eSCB as an adsorbent for RhB.
