Adsorption; adsorption
Transfer of compounds in solution to the surface of a solid and solid-solute interactions.
Coagulation-flocculation; Coagulation – flocculation
Mechanism and process for physicochemical treatment to destabilize and aggregate particles or colloids and separate them from the aqueous phase by settling.
Diagramme de spéciation; Speciation diagram
Presence of metal species as a function of experimental conditions (pH, temperature, etc.).
Electrolysis; Electrolysis
Separation process recovery of ions in solution under the influence of an electric field used to extract the ions present in solution. Cations (positive ions) are directed towards the cathode (–) and anions (negative ions) towards the anode...

Standardization
Numerous international and French standards exist for specific assay methods by metallic element or analytical technique. They are constantly evolving, thanks to the development of recent techniques (mercury determination by atomic fluorescence spectrometry in 2002, application of inductively coupled plasma mass spectrometry (ICP-MS) in 2005) and the improvement of older ones (trace element determination by graphite furnace...
