The Sorption of Humic Acids to Mineral Surfaces and Their Role in Contaminant Binding

Journal Article · · Science of the Total Environment
Humic substances dissolved in groundwater may adsorb to certain mineral surfaces, rendering hydrophilic surfaces hydrophobic and making them sorbents for hydrophobic organic compounds (HOC).
