Pretreatment of Complexed Metal Wastewaters

摘要: This study investigates the applicability of hydroxide precipitation to complexed metal wastewaters using inorganic cations that may function as ligand sharing agents. Within this context Ca 2+ , Fe 3+ Mn and Mg with metals Cd Cu EDTA NTA ligands are used define systems for which theoretical experimental evaluations made. Results indicate calcium is only cation effectively binds makes it possible apply precipitation. not effective due their rapid oxidation. found partly but be adequate pretreatment purposes.
