Abstract
Abstract A fluid, including a gas or a liquid, is flowed through a cylindrical enclosure and subjected to ultraviolet radiation to make predetermined ions more susceptible to a magnetic field established within the fluid by a magnet positioned around or within the enclosure. The ions are moved in a vortex motion within the magnetic field so that like ions converge at a focal point from which fluid containing a higher concentration of these ions is removed.

Independent Claim
29 words
In a process as claimed in claim 1 wherein the wave lengths of the electromagnetic energy are substantially within the spectrum of ultraviolet and up to the visible range.
Claim 2
Dependent Claim
15 words
In a process as claimed in claim 1 wherein liquid is introduced into a container.
Claim 3
Dependent Claim
23 words
In a process as claimed in claim 3 wherein the liquid is introduced tangentially to a cylindrical container to induce the vortex motion.
Claim 4
Dependent Claim
20 words

Claim 6
Dependent Claim
17 words
In a process as claimed in claim 1 and removing the liquid having a low ion concentration.
Claim 7
Dependent Claim
28 words
In a process as claimed in claim 1 wherein the electromagnetic energy has varying wave lengths corresponding to the ions of different materials which are to be separated.
Claim 8
Dependent Claim
21 words
