Abstract
Systems and methods are provided for the transport and separation of transition metal solutes using magnetic fields. A high-gradient magnetic field can be generated between the flat-faced poles of an electromagnet. The magnetic separation process can be enhanced by the aggregation of paramagnetic metal solutes into clusters, which are predicted to be two orders of magnitude larger than individual solute units.
Claims20
A method for separating metal solutes out of a solution, the method comprising:
- flowing the solution through a container that comprises a filter;
- applying a magnetic field to the container while the solution flows through the container, wherein at least one paramagnetic solute from the solution is captured on the filter;
- deactivating the magnetic field;
- and
- collecting the at least one paramagnetic solute from the filter.
A system for separating metal solutes out of a solution, the system comprising:
- a container that comprises a filter and that is configured to flow the solution therethrough;
- an electromagnet disposed around the container and configured to apply a magnetic field to the container while the solution flows through the container, such that at least one paramagnetic solute from the solution is captured on the filter;
- and
- a pump connected to the container and configured to flow the solution through the container.
