Abstract

Cr6+ complexed with diethyldithiocarbamate (DDC) was extracted into 0.1 volume of octanol in the presence of citric acid. The extracted compound was determined to be CrOH (DDC)3 + by electrospray ionization mass spectrometry. The peak at m/z 513 derived from 52Cr was so high that only 5 pg of Cr6+ could be determined in 10 min.
