A simple, fast and sensitive analytical method was developed for speciation of iodine in edible salts and human urine samples by short column ion chromatography coupled with inductively plasma mass spectrometry. Using a commercial anionic column of 50 mm length and 8 mmol L−1 of (NH4)2CO3 as the mobile phase, the total separation time was only 170 s, and limits of detection of 0.015 and 0.081 μg L...
Dispersive liquid–liquid microextraction (DLLME) was combined with flow injection inductively coupled plasma mass spectrometry for simultaneous determination of cadmium, lead and bismuth in water samples. The metal elements were complexed with sodium diethyldithiocarbamate, and then the complexes were extracted into carbon tetrachloride by using DLLME. Under the optimized conditions, the enrichment...
