Abstract
A method for concentrating contaminated sorbate in a solution which includes contaminated sorbate and clean sorbate is described wherein contaminated sorbate having a freezing point which is higher than the freezing point of the clean sorbate is cooled to a temperature below the freezing point of the contaminated sorbate and above the freezing point of the clean sorbate to concentrate the contaminated sorbate by cycling alternately from a desorption cycle to an adsorption cycle. By maintaining the solution at a temperature between the freezing point of the contaminated sorbate and the freezing point of the clean sorbate, the clean sorbate can be evaporated off.
