Purpose of this research is to study the interfacing of ion chromatography (IC) with dc plasma atomic emission spectrometry (DCPAES), tailoring the combined system to trace metal speciation in aqueous solutions. The DCPAES will serve as an element selective method of detection (ESD) for ion chromatographic effluents. Arsenic, chromium, iron, manganese, nickel, and vanadium were used as examples in the study. The work focused on: (1) evaluation of the factors that influence coupling of IC with DCPAES; (2) evaluation of influential chromatographic parameter such as type of column, eluent composition and element flow rate; (3) evaluation of sample matrix effects; and (4) development of procedures that can be employed to enhance measurement sensitivity. The methods will be applied in the analysis of selected environmental samples and energy related materials such as fossil fuels.
