Zirconium compounds have been used in dialysis as ion-exchange agents for the removal of a variety of inorganic ions extracted from blood, including the breakdown products of excess urea. The purpose of this study was to further develop a quick, reliable, spectrophotometric assay for residual zirconium ions in solution at the ppm level. The reagents involved chrome azurol S in acetate buffer and a variety of soluble zirconium compounds, including zirconyl chloride, zirconium phosphate, and zirconium bicarbonate. This standard-addition method is highly pH sensitive, and it was refined to extend the linear dynamic range to &lt; 5 ppm zirconium in solution.
