Zirconium Analysis Using Automated Photometric Titration

Zirconium can be determined in acidic aqueous solutions (buffer pH 1) by direct titration with EDTA. Eriochrome cyanine R is used as indicator. For equivalence point indication, the Optrode is used at a wavelength of 520 nm. This application note demonstrates the automatic photometric titration of zirconium using 907 Titrando.
