摘要
Abstract
In order to improve detection efficiency,microwave digestion-atomic fluorescence spectrometry was used to digest and determine total arsenic in rice flour.Microwave digestion was employed as the sample pretreatment method,and the optimal analytical conditions for microwave digestion were established.The parameter settings of the atomic fluorescence spectrometer and relevant environmental parameters affecting arsenic determination were clarified.Arsenic content in three laboratory standard rice flour samples was determined,and recovery tests were conducted on actual collected rice flour samples.The results showed that the measured arsenic values in the three standard rice flour samples using microwave digestion-atomic fluorescence spectrometry were within the certified reference ranges,with recovery rates of 99.5%-107.0%.The spiked recovery rates for actual rice flour samples ranged from 100.4%to 104.1%.The results were satisfactory,indicating that this method was simple to operate,stable,and practical,making it suitable for the determination of total arsenic content in rice flour in routine laboratories.关键词
