Abstract:Based on flow injection analysis (FIA), a flow-spectrophotometric method has been developed for the determination of composition of complexes with single standard gradient techniques under non-equilibrium state. Only one central ion standard solution and one coordinator standard solution are needed in this simple method. Satisfactory results have been obtained for the composition of some binary and tertiary complex systems.
Key words: flow-spectrophotometry gradient-dilution composition of complex
