Much progress has been made involving the interaction of atrazine (Atz) with natural geosorbents like Fe(hydr)oxides, organic matter, and clay minerals. However, the properties of the humic acid-Fe(hydr)oxides-clay composites ...

Slow-release fertilizers have been proposed as tools to increase P fertilizer use efficiency in tropical acidic soils with high P adsorption, low P availability, and mobility. However, results have been controversial since ...

The adsorption of phosphate onto CaCO3–montmorillonite (calcite–M) was studied in a series of batch experiments and in a wide range of phosphate concentration (5–160 μM). Our results show that phosphate adsorption is ...

The adsorption of the herbicide paraquat (PQ2+) on goethite and on the binary system humic acid-goethite has been studied in batch experiments by performing adsorption isotherms under different conditions of pH, supporting ...

In order to be able to make predictions about the bioavailability and transport of contaminants and nutrients in soils, detailed knowledge is required about the adsorption of natural organic matter on the surface of oxides, ...
