Abstract
Neutralization of H-mordenite with NaOH follows diffusion kinetics with the diffusion of sodium cations into the mordenite as rate-determining step; neutralization curves are determined by the H3O+→Na+ ion exchange isotherm. With KF solutions, all aluminium can be extracted from the lattice of NaY-zeolite.
Abstract
Нейтрализация Н-морденита NaOH протекает по диффузионной кинетике, где ступенью, лимитирующей скорость процесса, является диффузия натриевых ионов в морденит. Кривые нейтрализации были определены с помощью ионообменной изотермы H3O+→Na+. С помощью раствора KF весь алюминий может быть экстрагирован из решетки цеолита NaY.
