摘要
Ultrasonic assisted-acid leaching as a fast and accurate sample preparation method is coupled with tungsten coil electrothermal atomic absorption spectrometry(WC-ETAAS)for the determination of trace cadmium in rice.The limit of detection for cadmium was 6 pg,while the upper linear dynamic range was 40 ng/mL.
