本文采用流动注射 氢化物发生 原子吸收光谱法测定了果胶铋中铋的含量 ,方法简单、快速、准确 ,考察了实验参数对测定果胶铋中铋的影响。线性范围为 0 0 0～ 4 4 0 0ng·mL- 1 ,工作曲线回归方程为A =0 0 12 +0 0 17c(c:ng·mL- 1 ) ,相关系数r=0 9995 ,检测限为 0 0 95ng·mL- 1 ,回收率在 97 3%～ 10 3 3% ,用于实际样品的分析结果满意。 In this paper, flow injection hydride generation atomic absorption spectrometry was used to determine the content of bismuth in bismuth pectin. The method was simple, rapid and accurate. The influence of experimental parameters on the determination of bismuth in bismuth pectate was investigated. The linear range was 0 0 ~ 4 4 0 0 ng · mL-1. The regression equation of working curve was A = 0 0 12 +0 0 17c (c: ng · mL-1) with correlation coefficient r = 0 9995. 0 0 95ng · mL-1, recoveries ranged from 97 3% to 10 3 3%, which were satisfactory for the analysis of the actual samples.
