摘要:
Solvent sublation, a method related to ion flotation, was studied by sublating hexadecyltrimethylammonium bromide and Methyl Orange into 2-octanol. It was shown that if the aqueous solution was saturated with 2-octanol, removals of Methyl Orange were much slower than with unsaturated solutions, because the 2-octanol. tended to exclude collector from the bubble surface. The amount of Methyl Orange sublated was found to be different from that at liquid-liquid equilibrium, although the system reverted to the latter state if the sublation was discontinued and the solution was stirred. The organic phase retained any material passed into it and, other than the effects due to solubility, its presence had little influence on the processes occurring in the bulk of the aqueous solution. A detailed mechanism for sublate removal by solvent sublation is proposed.
