溶剂萃取—苯芴酮石墨炉原子吸收法连续测定岩石矿物中锗、铟、镓

SOLVENT EXTRACTION—CONTINUOUSLY DETERMING Ge, In, Ga IN ROCKS AND MINERALS BY USING ATOMIC ABSORPTION METHOD WITH BENZFLUORENONE GRAPHITE FURNACE^-

甲基异丁基甲酮(MIBK)—苯芴酮同时萃取,利用自制的简易石墨炉平台,以镍和钒作基体改进剂测定锗、铟和镓。方法简便、快速,适合于岩石矿物中锗、铟、镓的连续测定。

By means of simplified, self-made graphite furnace bench, and taking Ni and V as the basic improvers, Ge, In and Ga are determined as well as methyl isobutyl ketone(MIBK) and benzfluorenone are simultaneously extracted. This is a simple and high-speed method, It is suitable for continuously determining Ge, In, Ca in rocks and minerals.
