A Rapid and Multi-Element Method for the Determination of As, Cd, Ni, Pb, Sn, and Zn in Scallops Using High Definition X-Ray Fluorescence (HDXRF) Spectrometry

The objective of this study was to develop and validate a quick and easy method for the quantification of arsenic (As), cadmium (Cd), nickel (Ni), lead (Pb), tin (Sn), and zinc (Zn) by high definition X-ray fluorescence (HDXRF) spectrometry in scallops. The optimal moisture content (less than 7.5%),...

Description
Summary:The objective of this study was to develop and validate a quick and easy method for the quantification of arsenic (As), cadmium (Cd), nickel (Ni), lead (Pb), tin (Sn), and zinc (Zn) by high definition X-ray fluorescence (HDXRF) spectrometry in scallops. The optimal moisture content (less than 7.5%), particle size (0.180 mm), sample weight (0.70 g), and measurement time (600 s) of scallops using HDXRF were determined. A new scallop model of HDXRF was established based on the principle of linear correlation and the fundamental parameter (FP) method. The total time to analyze samples by HDXRF was less than 15 min. Figures of merit such as sensitivity, accuracy, precision, repeatability, and stability were evaluated. The LODs of As, Cd, Ni, Pb, Sn, and Zn were 0.072, 0.070, 0.502, 0.063, 0.033, and 4.383 mg/kg, respectively. The RSD values of the detection for precision, repeatability, and stability were less than 10%. During the validation step, the concentration of elements obtained by HDXRF was systematically evaluated against those obtained from inductively coupled plasma mass spectrometry (ICP-MS). This feasibility study demonstrated the good potential of the HDXRF technique as an accurate, simple, and rapid method.
