Abstract

Trace amount of cadmium was quantitatively extracted with 1% Aliquat 336-MIBK from 0.2M KSCN and 0.01M-HCl. Test tubes with a screw cap stopper were used for extraction in place of conventional separating funnels and organic solvents used were less dense than water. In this analysis, 22 times concentration effect was achieved with higher selectivity without interference. The detection limit of cadmium was 0.7ppb, therefore trace cadmium was easily analyzed by this method. The proposed method was applied to the determination of cadmium in blood serum and extraction mechanism was elucidated.
