Short Description of your Research or Creative Project (700 characters or less)

A sensitive flow injection (FI) system for determining dissolved iron concentrations involved a complex manifold: peristaltic pump, two electronically actuated 6-port, 2-postion injection valves, UV-Vis spectrophotometer and a desktop computer controlled by a software program for data acquisition. The FI method allows for direct preconcentration of iron in samples at trace metal nanomolar concentrations using the catalytic colorimetric indicator N, N-dimethyl-p-phenylenediamine dihydrochloride. Toyopearl AF-Chelate-650M chelating resin is used to remove the need for sample treatments before preconcentrating and eliminate interferences from iron binding to organic ligands in the sample matrix
