Determination of cadmium in rice bran oils by ICP

In this study, an ultrasound-assisted extraction procedure method using diluted acid followed by inductively coupled plasma mass spectrometry was developed for the determination of Cd in RBOs. Key parameters that affect the ultrasound-assisted extraction of Cd, namely, ultrasonic power, acid extractant, extractant/oil ratio and sonication time, were investigated in detail.
