A simple method for the determination of chromium(III) and total chromium in a flow injection system comprising chelating ion-exchange and flame atomic absorption spectrometry (FAAS) was described. A minicolumn (85 mm x 1.6 mm i.d.) filled with a poly(aminophosphonic acid) chelating resin (PAPhA, 20

For on-line preconcentration of Cr(III) and Cr(VI), several functionalized cellulose sorbents, a chelating resin and conventional ion-exchange resins were examined. Cellulose with phosphonic acid exchange groups was found to be superior for the preconcentration of Cr(III), but a cellulose derivative
