Abstract
The interactions between the liquid phase of sewage sludge and soil have been investigated. The chromatographic aspects (retention volumes and dynamic capacities) have been studied by breakthrough curves of copper on soil not treated and those treated with the liquid phase. The nature of the organic compounds retained by soil during the adsorption processes have been characterized using selected analytical techniques. The breakthrough curves are remarkably influenced by organic compounds -soil interactions. The specific retention volume depends on the nature of the organic matter adsorbed.
