Wilson, Aaron D; Orme, Christopher J.

Draw solutions comprising at least one N-cyclicalkyl-cycloalkylamine and a secondary solvent. The N-cyclicalkyl-cycloalkylamine comprises the chemical structure: ##STR00001## wherein n is 0, 1, or 2, n' is 0, 1, or 2, and each of R.sup.1-R.sup.6 is independently selected from the group consisting of an alkyl group, an alkoxy group, an acetyl group, an aryl group, a hydrogen group, a hydroxyl group, and a phosphorus-containing group. Methods of treating a liquid using the draw solution are also disclosed.
