Bismuth Determination by Controlled-Potential Coulometry: Developing a Highly Accurate Procedure based on GET 176
In this work, we develop a procedure for reproducing the units of bismuth mass fraction in metallic bismuth and those of bismuth (III) mass concentration in bismuth nitrate solutions by controlled-potential coulometry based on the GET 176-2019 State primary standard of mass (molar, atomic) fraction units and mass (molar) concentration of components in liquid and solid substances and materials based on coulometry. The results obtained can be used when manufacturing certified reference materials (CRMs) for the composition of high-purity bismuth and CRMs for the composition of solutions of bismuth (III) ions directly traceable to GET 176-2019. These CRMs may find application in pharmacological, metallurgical, and nuclear industries.
