Comparison of Four Pretreatment Methods for Total Arsenic in Spirulina by Atomic Fluorescence Spectrometry
Determination of total arsenic in Spirulina by atomic fluorescence spectrometry.The best pretreatment method for Spirulina was selected among dry method,low temperature wet method,high temperature wet method and microwave digestion method based on the correctness,precision and recovery.The repeatability of the method was verified by personnel comparison and instrument comparison test,which indicated that the atomic fluorescence spectrometry with high temperature wet method is an effective method for the determination of total arsenic content in Spirulina.
