From: Decontamination of water co-polluted by copper, toluene and tetrahydrofuran using lauric acid
Bottle tests conducted using aqueous solutions of 0.03 M CuCl2 and CuSO4, using 30% or 50% THF v/v relative to water, at circum-neutral pH. Copper ions partition in the THF phase only at circum-neutral, while they remain solubilized in water at pH = 2 and precipitate in part out of solution at pH = 13 (Fig. S10, supporting information file). Images were taken after leaving vials to sit overnight.
