✦ Synopsis

Nonlinear regression was applied to three empirical equations to model the response of a solid-state lead ion-selective electrode (ISE). One particular equation, previously reported to describe the response of a fluoride ISE, was found to also describe the response of a solid-state lead ISE. Nonlinear regression was applied to the early portion of the response curve for the lead ISE and used to estimate the equilibrium potential for a range of test solutions.
