Abstract
The use of a precolumn or microreactor with KOH and NaOH packings is described for the degradation of twenty halogenated pesticides and PCBs. In both cases the recoveries and their time degradation development are studied. It is found that after 48 h of conditioning of the precolumn or the microreactor, the recovery of aldrin and several other organochlorines is quantitative. For those pesticides which give a partial recovery, the microreactor is more convenient to use. For trifluralin, heptachlor, heptachlor epoxide and mirex the recoveries are lower than those obtained with ethanolic KOH.Keywords
