ABSTRACT:
A technique is disclosed herein for separating out one group of polar particles for example PCB molecules having polar moments of given magnitudes, from a separate group of polar particles, for example oil molecules having polar moments of lesser magnitude, in a mixture of the two. This is accomplished by utilizing a chamber containing a substance which has an affinity for the first particle, preferably neoprene in the case of PCB. The substance is carried by arrangements of electrodes or the like which produce a non-uniform electric field in the chamber which causes the first particle, e.g. the PCB, to be attracted toward the substance carried by the electrodes, e.g., the neoprene, faster than the second particles. In this way, first particles are separated out from the mixture and are absorbed by a particle collecting substance of suitable type.
