Fast and Slow Phosphate Sorption by Goethite-Rich Natural Materials
Adsorption Ferrihydrite Goethite Iron oxides Phosphate Porosity Silicate Sorption
2011/11/30
Abstract: Although phosphate sorption by goethite and other less-abundant Fe oxides strongly influences the concentration of this anion in the soil solution and aquatic environments, relatively little...
