Brazilian Red Latosol a Typic Soil as an Exchanger: A Thermodynamic Study Involving Cu, Zn, Cd, Hg, Pb, Ca and Na
Adsorption Ionic Exchange Isotherm Langmuir Method Red Latosol Soil
2011/12/9
Abstract: The thermodynamic cationic exchange process involving divalent (Cu, Zn, Cd, Hg, Pb and Ca) and monovalent (Na) cations in Brazilian red Latosol soil was studied. Using a batchwise method, th...
Thermodynamic Study of Na-K-Ca Exchange Reactions in Vermiculite
