Foamy Complex Formation for Removing and Recovering of Heavy Metal Ions in Dilute Solutions with N-Monodecanoyl Diethylenetriamine

In order to highly selectively remove and recover heavy metals, usually harmful, from wastewater, a modified foam-separating method using a fatty compound, i.e. N-monodecanoyl diethylenetriamine, was investigated on real and model wastewater, containing several kinds of metals. This agent forms soluble and foamy complexes with the metals.
