原子吸收分光光度计(不加火焰)测定铋

Determination of Bismuth by Atomic Absorption Spectrophtometer Without Flame

利用铋碘阴离子与碱性染料阳离子形成离子缔合物的胶束增溶光度法近有报道。而采用原子吸收分光光度计(不用火焰)测定铋的含量尚未见报道。本文根据铋碘阴离子与罗丹明B形成缔合物最大吸收波长为590nm的特点,以钠灯作光源,试用原子吸收分光光度计兼作紫外——可见分光光度计使用,并与721型分光光度计比较,结果满意,证明是可行的。 1 试验部分 1.1仪器与药品 WYX-401型原子吸收分光光度计(沈阳市分析仪器厂)

A simple and satisfactory method has been developed for the determination of bismuth. We can just rely on Atomic absorption spectrophotometer without flame in place of UV-Visible spe-ctrophotometer. The operation is very simple yef it can raise the efficiency of atomic absorption spectrophotometer. This experiment offers a possibility for us to find new applications of Atomic abso-rption spectrophotometer.
