Abstract
Glass surfaces modified with N-2-aminoethyl-3-aminopropyltrimethoxysilane have been titrated with copper(II) by constant rate thermometric titration and by manual potentiometric titration with Gran plot end-point location. The results indicate that the titrant reacts with the bound ligand in a two-step process, with the thermometric titration responding to the first step and the potentiometric titration responding to the combined steps.
