摘要
建立了香菇中亚硫酸盐的离子色谱检测方法。样品经过超纯水浸提后,过滤进样分析。选用IonPac As19型分离柱,4mmol/LNaOH为淋洗液。此方法的线性相关性好,相关系数为0.9994,相对标准偏差为0.9%~2.1%,样品的加标回收率在97.0%~102.0%之间。
A method for the determination of sulfite in lentinus edodes by 1on cnromatograpny 18 cstabished. Ionpac Asl9 is chosen as the separation column and 4mmoFL NaOH as eluent. After digestion using deionized water and filtration with 0.45p^m pinhead percolator, the samples are injected and analyzed. It is indicated that this method has a good relativity (r=0.9994). The relative standard deviations and recoveries are 0.9%-2.1% and 97.0%~102.0%, respectively. The method is proved to be rapid, accurate and practical.
