Foreword

The natural zeolites are an abundant resource, available as a relatively cheap commodity mined in many countries covering all the continents of the world.

They have the unique ability to act as selective cation-exchangers and ad/absorbents to remediate aqueous effluents, such as nuclear, mining and tannery waste waters, and agricultural run-off. Additionally they can be surface modified to act as anion exchangers and to remove organic contaminants.

There is a vast literature covering these areas and this e-book is the first to present a comprehensive account of this important area of environmental science and technology.

The author draws on her own extensive studies supported by elucidations of the underlying theory to ion exchange and adsorption which are comprehensive. The subject is introduced by detailed considerations of natural zeolite diagenesis and the crystal structures of relevant minerals and later complimented by descriptions of their characterisation.

Attention is paid to the methods of surface modification available, with details of their syntheses.

The book will be a vital resource to the many workers in environmental clean-up throughout the world and is eminently suited to be an introductory text to students and workers commencing work in this significant area.

Professor Alan Dyer, 2014.


Preface

The author of the eBook is a former project leader responsible for clinoptilolite-rich tuff utilization in water treatment and water purification processes, currently preparing some new advanced or innovated postmodified zeolite adsorbents that can be used more universally, testing together with plenty of other economic feasible natural or unconventional adsorption materials or even waste products and thus by contributing to future sustainability of our environment. Nearly all the examples contained in the eBook are based on real experimental data.

In the author¬īs memory such zeolite experts names like B.W. Mercer, L.L. Ames, F.A. Mumpton, R. Svetich, all from USA, A. Dyer from Great Britain or L. Liberti from Italy, will remain forever some of whom the author visited or met personally and was instantly impressed by their intense human approach, e.g. by Prof. Mumpton during the zeolite conference Slovzeo in High Tatra (former Czechoslovakia, 1984) and Zacatecas (Mexico, 2003), by Prof. Dyer at the International Conference on Occurrence, Properties and Utilization of Natural Zeolites in Budapest (Hungary, 1985) and also in University of Salford (Great Britain 2002), and by Prof. Liberti at the University of Bari (Italy, 1995).

The author was pleased by the warm welcome of the responsible zeolite chemist at TTSA and Waste water facility at Tahoe (California), (Dr. R. Svetich, in January 1995), facility which was the best and first in the world applying clinoptilolite-rich tuff for water treatment.

The author also admires the pioneering works of B.W. Mercer and L.L. Ames with their coworkers, published in 1975 under US Water Pollution Control Federation (WPCF) Journal, which was accidentally accessible at the author¬īs former employer Water Research Institute in Bratislava and offered great inspirations to zeolite researchers of that time.
