自 H·J·Cluoley 以苯芴酮作锗的比色测定以来,近年来得到了广泛的应用与发展。P.Stipanist 和 F.Hecht Ф.Г.Жаровский和А.Т.Пилипенко研究过苯芴酮锗的化合状态.探讨过苯芴酮锗在有机溶剂中大多不溶的原因。Н.Ф.Казаринова和Н.Л.Васильева由改进试剂着手,在苯芴酮上引入了-N(CH_3)_2基,增加了悬浊液的安定性和试剂的选择性。A.Hillebant 和 J.Host 用苯甲醇萃取,试图在真溶液中进行测定。Y.Oka 等用聚苯乙烯醇作保护剂改善了悬浊液的分散度,使应用范围扩大。C.L.Luke 和 M.E.Campbell
Since H.J.Cluoley benzofluorenone as germanium colorimetric determination, in recent years has been widely used and developed. P.Stipanist and F.Hecht Ф.Г. Жаровский and А.Т.Пилипенко studied the state of the compound of germanyl fluorenone germanium.We discussed the reason that germanium perphenone germanium was mostly insoluble in organic solvents. Н.Ф.Казаринова and Н.Л.Васильева by the improvement of reagents to benzene-fluorenone introduced -N (CH_3) _2-based, increased stability of the suspension and reagent selectivity. A. Hillebant and J. Host extracted with benzyl alcohol in an attempt to determine in true solution. Y. Oka and other polystyrene as a protective agent to improve the dispersion of the suspension, so that the scope of application expanded. C. L. Leuke and M. E. Campbell
