## Abstract Porous silicaβzirconia membranes with pore diameters from 0.8 to 2 nm were prepared by a solβgel process, and applied to the separation of alcohols (hexanol, octanol, decanol) and alkanes (hexane, decane, tetradecane) in ethanol solutions by reverse osmosis over the temperature range fr
Extraction of heavy metal from contaminated soils with chelating agents is reported in the literature. This paper explores the feasibility of nanofiltration for separating chelating agents from heavy metals, which would make it possible to reuse chelating agents. The influence of membrane characteri
