Determination of Iron in Sucrose by Microwave Digestion and Inductively Coupled Plasma Mass Spectrometry
Inductively coupled plasma mass spectrometry(ICP-MS)was used to determine the elemental iron content of the four types of sucrose after samples of black,brown,yellow rock,and white granulated sugar were chosen.The method's limits of detection(LOD)and quantification(LOQ)were 2.0 mg·kg-1 and 0.6 mg·kg-1,respectively,and the elemental iron had good linearity in the concentration range of 0～1.00 mg·L-1.The results were also good in terms of recoveries and precision.Its spiking recoveries and accuracy were good,and the standard substances'analytical validation findings were satisfactory.
