Project Details:

Lead-Based Second-Kind Electrodes in Aqueous Medium and in Aqueous-Organic Solvent Mixtures

Project No.:550-63-97
Start date:1997-01-01
End date:2002-12-31
Division:Analytical Chemistry Division
Objective:

The availability of second-kind electrodes for sensing ions other than halides, is poor in aqueous media and even worst in aqueous-organic solvent mixtures. Extensive measurements have allowed a critical revision of all existing data and procedures, together with extension of the field of application. Directions for optimization of electrode designs, set-up, standardization and operation procedures (both for thermodynamic and analytical applications) are now focused. Standard electrode potentials have been critically redetermined, or newly determined. The parallel performances of second-kind lead/lead chromate, lead/lead sulphate, and lead/lead phosphate electrodes have been calibrated.
