A Selective Fluorescent Probe for Ferric Ion Based on Rhodamine 6G

摘要

Ferric ion is served as a crucial and plentiful metal ion in the living systems and in environment.1 It performs vital functions in several pathological and biological processes,such as enzyme catalysis,cell metabolism,oxygen,and electron transport.2 Deficiency or excess of Fe~(3+)will trigger numerous illnesses including anemia,Parkinson's syndrome,and Alzheimer's disease.3 To deal with Fe~(3+)pollution,it.is important to monitor iron concentrations in ecological water.Consequently,a significant of consideration has been dedicated to develop diverse approaches to detect Fe~(3+)quantitatively.Fluorescence analysis has been extensively used due to the advantage of high sensitivity,easy operation,and prompt response,and so on.
