Kinetic Study for Adsorption of Cu2+ onto Modified and Unmodified Peanut Hulls

The need to remove heavy metal ions from drinking water has led to the creation of many chemical grade resins which have to be disposed of after use. Using biodegradable remediates such as peanut hulls is a cost-effective solution. The purpose of this experiment is to study the kinetics of the adsorption of Cu2+ onto ground peanut hulls of sizes between 0.5-1.0 micron. The hulls were modified in a NaOH and H2O2 solution, and kinetic studies were carried out on both unmodified and modified hulls by measuring aliquots of the copper-containing solution at various times after mixing with the hulls. Copper concentration was measured using flame atomic absorption spectroscopy. The data will be fit to different kinetic models, and a comparison of rate of adsorption of the different hull types will be presented.
