Kinetics of the PO4-P adsorption onto soils and sediments from the Mondego estu...
Otero, M.; Coelho, J. P.; Rodrigues, E. T.; Pardal, M. A.; Santos, E. B. H.; Esteves, V. I.; Lillebo, A. I.In order to assess the status of a North Atlantic Ocean Ecoregion (Mondego system, Portugal) after the implementation of a management programme, a study on PO4-P sorption was carried out. Considering that sorption velocity markedly determines the systems promptness to phosphorus external loading, the kinetics of the sorption of PO4-P onto estuarine sediments and the upstream agricultural soils was studied. The ...
Sorption-Desorption Behavior of Atrazine on Soils Subjected to Different Organi...
Lima, D. L. D.; Schneider, R. J.; Scherer, H. W.; Duarte, A. C.; Santos, E. B. H.; Esteves, V. I.Sorption of atrazine on soils subjected to three different organic amendments was measured using a batch equilibrium technique. A higher K(F) value (2.20 kg(-1)(mg L(-1))(-)N) was obtained for soil fertilized with compost, which had a higher organic matter (OM) content. A correlation between the K(Foc) values and the percentage of aromatic carbon in OM was observed. The highest K(Foc) value was obtained for the...
