Simultaneous temperature-assisted dispersive liquid–liquid microextraction of cobalt, copper, nickel and zinc ions from high-volume water samples and determination by graphite furnace atomic absorption spectrometry

Abstract: A rapid, efficient, and reliable sample preparation method based on temperature-assisted dispersive liquid–liquid microextraction was developed for simultaneous extraction of cobalt, copper, nickel, and zinc ions at a low level from high volume water samples.
