Lin Yu W. Chang Yuan Ze Institute of Technology, Taiwan Batch fractionation is employed in the present study to recover chemical solvents from highly toxic and concentrated liquid wastes generated in a chemical analytical laboratory. The chemical solvents recovered are of sufficient purity for reuse. Properly designed batch fractionation apparatus is economically attractive for dealing with these kinds of toxic liquid wastes. H.
