A simple, rapid, and efficient procedure, dispersive liquid-liquid microextraction (DLLME), has been developed for the extraction and preconcentration of platinum (IV) in environmental water samples. The factors relevant to the microextraction efficiency, such as the kind and volume of extraction and dispersive solvent, the extraction time, the pH in aqueous, and the salt effect, were optimized. Under the optimum conditions , the enrichment factor of this method for platinum was reached at 119. The detection limit for platinum was 0.3 ng mL-1 , and the relative standard deviation (RSD) was 0.42% (n = 10 , C = 10 ng mL-1). The method was successfully applied to the determination of trace amounts of platinum in environmental water samples.
