The solute then separates from the increased ionic strength solution as a separate phase. Once the solute is, for example, decanted off, the increased ionic strength aqueous solution can be converted back to water having its original ionic strength and reused. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with CO2, CS2 or COS.Type: ApplicationFiled: February 10, 2011Publication date: May 2, 2013Applicant: Queen's University at KingstonInventors: Philip G.

Publication number: 20120309661Abstract: The invention relates to environmentally friendly, multi-purpose, cost-effective compositions based on one or more special solvent that comprise only very small amounts of VOCs. The compositions are preferably one-system compositions. In preferred embodiments of the invention the compositions are even free of VOCs. Because of their low flammability or even non-flammability as well as their low VOC content the compositions guarantee higher workplace safety, reduced insurance costs and reduced costs due to environmental legislation.Type: ApplicationFiled: January 21, 2011Publication date: December 6, 2012Inventors: Jörg Adams, Fabrice Valchera
