Abstract:A recent advance in the application of rhodamine 6G to the photometric analysis of noble metals and rare metals is reviewed. This paper centers on extraction photometric analysis, floatation photometric analysis, fluorimetric analysis, water phase photometric analysis. Also considered are their systems of determination and the conditions of coloring reactions, maximum absorption, molar absorptivity, limit of detection, interference and the range of determination. The main characteristics of extraction photometric analysis, floatation photometric analysis and fluorimetric analysis are also introduced.Correspondent: Duan Qunzhang, Professer, Central South University of Technology, Changsha 410083, P.
