The comparison of protolytic properties of olygoethyleneamines bonded silica for modeling of internal pH gradients

Abstract

The potentiometric titration of silicas with ethyleneamine, diethilenetriamin and tetraethlenepentamine, bonded by epoxy groups was carried out. The polynom, describing the dependence of protonization constant from ionic strength and titration degree, was suggested. The Excel application "Alpha" for simulation of protonization constants was worked out.
