Abstract
The use of phillipsite- and chabazite- rich tuff wastes, from the huge deposits of Neapolitan yellow tuff for removing lead from water has been considered. The effectiveness of the removal process in the presence or absence of interfering cations has been demonstrated. The possibility of using the pozzolanic activity of the exhausted material to stabilize lead in a cement matrix is successfully accomplished, since materials with good mechanical properties and negligible lead release by leaching are obtained. The advantage to dispose of these materials in a segregate landfill instead of a more expensive sanitary landfill is highlighted.
