摘　　要： 面粉样品经简单的超声波萃取,离心分离,上清液过C_(18)固相萃取小柱后,采用电导抑制离子色谱法测定了面粉中氟、氯、溴、碘、亚硝酸根、硝酸根、硫酸根、磷酸根、溴酸根9种阴离子的含量。测定结果的相对标准偏差均小于8%,平均加标回收率在87.5%～96.0%之间。方法快速、简单,可满足面粉中9种阴离子的同时测定。 The flour samples were extracted by ultrasonic wave followed by centrifugal clear supernatant was eluted through the SPE - C18 column and the eluent was chromatography. Nine inorganic anions of fluorine, chlorine, sulfate, phosphate and bromate in flour were quantitative detection bromine, iodine, at the same time. separation. The detected by ion nitrite, nitrate, The RSD of the results were less than 8% and the mean recoveries were between 87.5% and 96. 0%. The developed method was simple, rapid and suitable to simultaneous determination of inorganic anion in flour.
