微波消解-电感耦合等离子体质谱法测定甘蔗中25种元素含量

摘要

A method of determining 25 elements in sugarcanes by ICP-MS with microwave digestion was set up. The parameters of microwave digestion and ICP-MS were optimized. The limits of detection were 0.00090~6.19 µg/g and the RSD were 0.3%~2.5%. The result showed that the method was good for determination of multi-elements in sugarcanes.%建立了微波消解-电感耦合等离子体质谱法测定甘蔗中25种元素的方法。确定了微波消解和电感耦合等离子体质谱仪的测量参数，该方法对各元素的检出限0.00090～6.19µg/g，相对标准偏差0.3%～2.5%，适用于甘蔗中多种元素的同时测定。
