a comparatively simple procedure, for the purpose of studying the reaction between the colorimetric reagent and metal ions and to search for a useful colorimetric reagent. The effects of the substituents introduced on the absorption maxima of the dyes and the metal chelates formed, and on the reactivities of the dyes with metal ions such as germanium(IV), zirconium(IV), and titanium(IV). 2′Sulfophenylfluorone
2,3,7-三羟基-9-(3'-硝基苯基)氟酮、2,3,7-三羟基-9-(4'-硝基苯基)氟酮和2,3,7-三羟基-(2'-磺基苯基)氟酮)氟酮是通过相对简单的方法合成的,目的是研究比色试剂与金属离子之间的反应并寻找有用的比色试剂。引入的取代基对染料的吸收最大值和形成的金属螯合物的影响,以及对染料与金属离子如锗 (IV)、锆 (IV) 和钛 (IV) 的反应性的影响。2'磺基苯氟酮金属螯合物可溶于乙醇或环己醇乙醇溶液。3'-硝基苯氟酮由于空白溶液的高稳定性、高灵敏度和低吸光度,是测定金属离子的最佳比色试剂。
