Determination of Migration of Hazardous Elements from Non-Stick Pan Materials in Five Food Simulants by ICP-MS

Abstract:

A method for the determination of seven hazardous elements in Non-stick Pan Materials in five food simulants by inductively coupled plasma mass spectrometry (ICP-MS) was established. Using this method, the experiments were carried out on the samples of imitated migratory elements (Cr、Mn、Ni、Cu、As、Pb、Cd) in food simulants of water, 4%(W/V) acetic acid solution, 10%(V/V) ethanol solution, 2g/L sodium chloride solution and olive oil. The sample preparation method of five food simulants was confirmed through experiment. Experiments by resolution, stability, sensitivity and other parameters were adjusted tuning instrument to determine the instrument to achieve the best working condition. The linear range of this methods was 0.1~50ng/ml. For all elements, the correlation coefficient of the calibration curves was above 0.9990 and the detection limits were within the range of 0.008~0.12ng/ml. Most of the recoveries at 1ng/ml concentration level was from 85.34%~112.3%, while the RSD was from 0.37%~4.1%.
