目前国内测定汽油中的微量铅多用分光光度法。这类方法操作复杂,分析一个样品需八小时,又要使用剧毒氰化钾和溴水等,需要改进。1961年国外已采用原子吸收法,近年来又提出用碳棒原子吸收测定汽油中的四烷基铅。用火焰原子吸收法采用向汽油中加入碘,甲基异丁酮稀释的方法消除汽油中铅的不同化合状态的影响。得到1ppb的检出下限。我们用钽舟无火焰原子化装置参考以前的工作,提出了一个可以测定高纯铂重整汽油 At present, the domestic determination of trace amounts of lead in gasoline spectrophotometry. Such methods are complicated to operate, requiring eight hours for a sample analysis, as well as using virulent potassium cyanide and bromine, which needs improvement. 1961 Abroad has adopted the atomic absorption method, in recent years has also proposed carbon rod atomic absorption determination of tetraalkyl lead in gasoline. Flame atomic absorption method using gasoline to add iodine, methyl isobutyl ketone dilution method to eliminate the impact of different combinations of lead in gasoline state. A detection limit of 1 ppb was obtained. We use the tantalum boat flameless atomization device reference to previous work, proposed a measure of high purity platinum reformed gasoline
