Abstract
Overview
ISO 11653:1997 specifies a laboratory potentiometric titration method for the determination of high cobalt content in steel after separation by anion-exchange chromatography. The standard describes sample dissolution, separation of cobalt from interfering elements on an ion-exchange column, oxidation and cleanup, reaction with potassium hexacyanoferrate(III), and potentiometric titration of the remaining reagent with a . It includes procedural details, reagent and apparatus specifications, and interlaboratory precision data.
