Abstract
After solvent extraction of soil and clean-up of the extract there is a possibility of reactions being induced photochemically in the solvent phase. In one recent instance such reactions, proceeding relatively quickly during 6-8 days, produced unknown compound(s) whose retention time in a column of 10% DC-200 on 80/100 mesh Gas Chrom Q coincided with that of pp'-DDT. Such interference could be eliminated by later treatment of the extract with concentrated sulphuric acid.Entities:
