Solvent Sublation Of Toluene From Aqueous Phase, Mei Chen

Theses

Solvent sublation, a surface chemical technique, was used to remove toluene from aqueous solution into a layer of paraffin oil.

Analytical methods for GC determination of toluene in both gas and aqueous phase were set up. The comparison of solvent sublation and conventional air stripping on toluene removal was carried out. It was found that solvent sublation provides significant improvement over air stripping in removing toluene from water, and reduces toluene emission to the atmosphere. The toluene emissions reduction by solvent sublation are 30%-70% under different conditions. The effects of air flowrates and thickness of organic layer were studied. Increased …
