Determination of Cadmium in Bivalve Molluscs by Microwave Digestion with Inductively Coupled Plasma-Mass Spectrometry

Article Preview

A method based on microwave digestion and inductively coupled plasma-mass spectrometry (ICP-MS) has been established for the sensitive determination of cadmium in bivalve molluscs. The application of the internal standards calibration improved the accuracy and precision values of the method. The relative standard deviation (RSD), the standard addition recovery value and the detection limit were determined as 4.25%, 94.74% and 0.005 μg/L, respectively. This method has been verified by the determination of cadmium in certified reference material kelp (GBW08517) and mussel (GBW08571). The method has been applied to determine the contamination concentration level of cadmium in seven kinds of bivalve mollusk samples. The results indicated that, among them, mud clam, scallop and oyster have relative high accumulation ability to cadmium.
