Dr. Ghabbour's research focuses on: isolation, purification, identification and characterization of natural organic matter especially, humic acids; establishment of standards and cross comparison of HAs from different sources; analysis and bioremediation of contaminated soil and water; thermodynamics and mechanisms of solute adsorption and metal binding by solid natural organic matter, especially humic acids, using XAFS, ICP-MS and NMR technology, SEM, TEM, XRD, FTIR, UV-vis, SEC and modeling; thermodynamics and mechanisms of the humic substance-clay/mineral-water interface; properties of humic acids aerogels; and therapeutic properties of humic substances and validation and quality control methods for therapeutic uses.
