中文摘要:

      考察了使用氢化物-原子荧光光谱法测定罐头食品中的锡时,酸介质、酸介质浓度、硼氢化钾浓度、遮蔽剂对荧光值的影响. 方法线性范围为0~250 ng/mL,相关系数为0.999 5,回收率为88.7%~102.74%,相对标准偏差为2.29%~3.58%.

英文摘要:

      The hydride-atomic fluorescence spectrometry is used to the determination of tin in canned food,effects of various aids,concentration of aids,concentration of KBH₄, and screening agent on the fluorescence intensity are studied. Under these conditions,the linear range of determination was 0~250 ng/mL,the related coefficient was 0.999 5,the recovery rate was 88.7%~102.74%,and the RSD was 2.29%~3.58%.
