Abstract
A rapid quantitative determination method of mercury, arsenic and arsenic, cadmium and chromium in strawberry was established. The sample to be tested was prepared into the solution to be tested, and the content of mercury, arsenic, cadmium and chromium were determined respectively on the machine. The results showed that the correlation coefficient of the standard curves of the four heavy metals was within 0.9961.000, and the detection limit was 0 mercury 0.028 g / kg, arsenic 0.062 g / kg, cadmium 0.14 g / kg, chromium 4.76 g / kg; the recovery was 80.2% 108.3% and 1.58% 26.34%; the test results of the standard samples were within the standard value. The method established in this experiment can determine the four heavy metals of mercury, arsenic, cadmium and chromium, etc. It has good linear correlation, low detection limit, good accuracy, high safety, simple operation, batch processing, and saves reagent consumables and detection time.
