Open-field experimentation of an innovative and integrated zeolitite cycle: project definition and material characterization

摘要: This study is a part of the European LIFE +2010 Project “ZeoLIFE—Water pollution reduction and water saving using natural zeolitite cycle”. It characterizes application Italian zeolite-rich pyroclastic rocks (zeolitites) as soil conditioner. Laboratory experiments will be tested on an experimental field in Codigoro area, Ferrara district (North-East Italy). The samples investigated are chabazite- phillipsite-rich all collected quarries from Central Italy: (1) Grosseto area (Sorano Sovana); (2) Viterbo (Farnese, Grotte Santo Stefano, Corchiano, Nepi), (3) Rome (Riano). All characterized by more than 30 % zeolite content, together with volcanic glass, feldspars, pyroxenes, micas. quantitative mineralogical characterization shows variable proportions quartz, illite, plagioclase, K-feldspar, calcite, dolomite, chlorite, serpentine, kaolinite, gypsum amorphous residual. Collected data confirm that conditioning soils selected can extremely promising for well evident improvement quality, contribute to define standard approach which surely find general above boundaries test.
