A detailed study hay been made on the analytical reaction of some 2,6,7-trihydroxy fluoione derivatives with 73 inorganic ions.The trihydroxyfluorones investigated include three 9-alkyl derivatives and nine 9-aryl derivatives.In 1N sulfuric acid solution, all of the fluorone reagents react with Sb、Sn、Sn、Bi、Fe、Ge、MoO4=、WO4=, forming orange or cherry-red precipitates.The color reaction is particularly sensitive to Sbt11, Snu and Sb、SnⅡ、Ge.
