Determination of Cadmium in wild and cultural laver by ICP-MS

Inductively coupled plasma mass spectrometry was used to determine the concentration of Cd in laver after microwave digestion. The result showed that the content of Cd in wild laver was higher than cultural laver by 2 times, and there were significant differences between them. The recovery and precision experiment proved this method was reliable and accurate to detect the standard reference material of spinach (GBW 08521).
