Abstract

In this research project, we evaluated the feasibility of using an agro-industrial waste product, chestnut shells, as a biosorbent for removing lead (Pb2+) from diluted aqueous solutions used as a model for water contaminated with low concentrations of heavy metals. The influence of the variables biosorbent mass (0.2-0.6 g), solution pH (4.5-5.5), and initial lead concentration (50-150 ppm) on the bioadsorption process was analyzed using a factorial experimental design (23+3) *2. The results showed that pH was the factor with the greatest statistical significance in the process. The experimental data were analyzed and the most appropriate mathematical model was determined using Minitab software, validated by the coefficient of determination (R2) and the adjusted coefficient of determination (adjusted R2).
