Application of SQUAD to the refinement of formal potentials from coulometric steady-state and spectrophotometric measurements.
The application of SQUAD to the refinement of formal potentials from potentiometric or coulometric steady-state and spectrophotometric measurements was tested. The formal potential thus obtained for the Fe(CN) (3-)(6)Fe(CN) (4-)(6) couple in 0.5 M H(2)SO(4) agreed with published data. This method was found to be satisfactory for the determination of typical standard potentials and it is suggested that it may be advantageous when dealing with multi-component systems.
