摘要：
A simple and sensitive solvent extraction-atomic spectrometric technique has been developed for the determination of hexavalent chromium in fresh and saline waters. The technique is based on the reaction of chromium with diphenylcarbazide. The method has been tested on a variety of water samples over an analytical range of 0-2 mug l(-1). A limit of detection of 0.024 mug l(-1) was achieved. Spiking recoveries in the range 87-115% were achieved in river water, drinking water and marine waters.
