The effect of drying and wetting of the deactivated (6% mositure) aluminium oxide column using n-hexane or benzene as eluting solvent was investigated in order to evaluate recovery rates of cetain hydrocarbon and organophosphorus pesticides. The dry aluminium oxide column showed the best recovery values for chlorinated hydrocarbon pesticides when eluted with n-hexane or benzene. The wet aluminium oxide column gave the best recovery values for organophosphorous pesticides when eluted with benzene. The dry aluminium oxide column also gave satisfactory recovery values for most of the tested organophosporous pesticides when benzene was used as an eluting solvent.
