Investigation of Heavy Metal Adsorption to Hydrothermal Char
PublicDownloadable Content
open in viewerSustainable solutions to remove heavy metal contaminants from the water supply are of critical importance to human health and the environment. This project investigates the use of hydrothermal char, a carbonaceous product of hydrothermal carbonization, as a heavy metal cation adsorbent. In this work, simulations based on density functional theory (DFT) are used to evaluate the adsorption of copper and lead to a proposed hydrothermal char molecule. It is shown that adsorption sites containing acidic hydrogens are most favorable. It is also shown that surface charge density, Born energy, and electric potential energy are strongly correlated to the computationally determined potassium exchange energy. A methodology for the experimental validation of the proposed approach is also provided.
