Removal of Refractory Organics by Aeration. VII. Solvent Sublation of Indene and Aldrin

Abstract
The solvent sublation of indene and aldrin from aqueous systems into mineral oil was studied. With indene, the effects of Ni(II) and Zn(II) were investigated; the usual salting-out effect was observed, with no indication of complex formation between the olefin and the nickelous ion. The effects of a number of alcohols on the solvent sublation of aldrin were determined; very small concentrations of alcohol increase the rate of aldrin removal, while larger concentrations decrease it by roughly an order of magnitude at mole fractions of alcohol of the order of 0.10. Methanol is less effective than ethanol or n-propanol in decreasing the removal rate at mole fractions above 0.02
