Abstract:

The residues of six arsenic species in edible parts of the Chinese mitten crabs (Eriocheir sinensis) were conducted by the high performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS). After pretreatment, extraction and degreasing, optimal separation and detection conditions were obtained by adjusting the suitable chromatographic column, mobile phase, pH and flow rate. The results demonstrate that the linear relationship of the six arsenic species could be observed in the range of 0~50 μg/L, and the R2 of the six arsenic species in the range of 0~50 μg/L is 0.999. The limit of detection is 0.0060~0.0912 μg/kg and limit of quantification is 0.020~0.304 μg/kg. The recovery of this method is 70%~120% and the relative standard deviations (RSDs) are less than 5%. This method establishes a reliable method for the detection of arsenic residues in the Chinese mitten crabs, and could provide a technical support for the rapid detection of the arsenic residuals in aquatic products.
