The optimization of a simple multi-element extraction method employing an experimental design approach is described. The method uses centrifugation to pass one extractant solution at varying pH through a contaminated soil sample. The nature and concentration of the acid, rate of centrifugation and time, number of sequential leachates and the ratio of extractant volume:sample weight have been studied in order to obtain the optimum conditions for extraction.
