摘要
Abstract
Objective] The aim was to determine several heavy metals content in rice rapidly and accurately, to provide reference for research on heavy metal pollution in rice.[Method] The content of lead, arsenic, cadmium, mercury, chromium, copper, zinc and selenium in rice were determined by inductively coupled plasma mass spectrometry (ICP-MS) with microwave digestion.The conditions for the determination of 8 ele-ments were optimized.[Result] The results showed that the correlation coefficient of 8 elements in rice is greater than 0.999 6 in the linear range, the detection limit is 0.18 -20.00 μg/kg, the recovery rate is 91.6%-106.0%, the relative standard deviation is 0.5%-9.7%. [Conclusion] The method is simple, sensitive and accurate.It is suitable for the detection of the content of lead, arsenic, cadmium, mercury, chromium, copper, zinc and selenium in rice.关键词
