Title: Solvent extraction method
Inventor: RATHIE NORMAN
IPC: C22B3/26
Filed: 1992-10-01
Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a method for selectively recovering metal ions and metal complexes from aqueous feed streams, containing high solid loadings.  The invention requires the use of a metal chelating agent contained within an organic phase to be combined with the feed stream in such a manner as to permit the formation of the desired metal complexes within the organic phase.  Recovery of the organic phase from the feed stream is achieved through the use of non-plugging and/or fouling disengagement devices.  The system further provides for improved recovery economics of metals in feed streams requiring extensive neutralization, by permitting the use of lower cost neutralizing agents, which will form solids in the solvent extraction unit.

Title: Photoionization ion mobility spectrometer
Inventor: SPANGLER GLENN E
IPC: G01N27/64
Filed: 1993-04-21
Abstract: An improved photoionization ion mobility spectrometer is disclosed which utilizes a flashlamp (12) as the source for ioni-zation. A gas sample is introduced via a carrier gas into an ionization chamber (30) which is part of the spectrometer cell. Ioniz-able molecules contained in the injected gas sample are ionized by the ultraviolet light emitted from the flashlamp. The ionized molecules are attracted by an electrostatic drift field into a drift chamber (20) and travel therethrough against the flow of a drift gas counter-current thereto until they are captured by a collector located in the drift chamber opposite to the ionization chamber. A dopant with an effective ionization potential lower than the photon energy of the emitted light can be introduced into the ioni-zation chamber to further improve the sensitivity and specificity.
