研究离子色谱法测定面制品中溴酸盐的方法。制备净化柱以及研究其对样品的的净化效率,并对离子色谱仪分析溴酸盐条件进行优化。发现自制的Ag型净化柱对干扰离子氯离子的净化效率达到85%以上。条件优化后溴酸盐和其他离子在离子色谱中的分离度都在1.5以上。结果表明,自制的样品净化柱和离子色谱法在面制食品中的溴酸盐的测定中,有现实的应用意义。 Study on ion chromatography method for determination of bromate in flour. The purification column was prepared, its purification efficiency on the sample was studied, and the conditions of the bromate analysis by ion chromatography were optimized. It is found that the purification efficiency of homemade ion-exchange ion-impinging ion-purification ion-exchange chromatography is over 85%. After optimization, the resolution of bromate and other ions in ion chromatography are above 1.5. The results show that the homemade sample purification column and ion chromatography in the determination of bromate in the food preparation, has practical significance.
