SCI Separation Science and
Technology group Ion Exchange Award 2004
Three winners receive their IX awards at Cambridge conference
The IX Award is given by the SCI Separation Science and Technology
Group to distinguished scientists and engineers who have made
a significant contribution to the science and promotion of
ion exchange in any field within the context of SCI activities.
The Award was instigated in 1984 as part of the Ion Exchange
Trust Fund which was set up in that year. Recommendations
for the Ion Exchange Award are made every four years in the
year of the IEX Conferences by the IEX Organising Committee
in conjunction with the Separation Science and Technology
Committee. The list of recipients includes some of the most
distinguished names in ion exchange.
In 2004 there were three awards made, to Professor Wolfang
H. Höll, Mr Michael Sadler and Professor Arup K Sengupta.
The presentations were made by David Naden, Chairman of the
SS&T Group Committee, in a special ceremony on 7 July
2004 at the IEX2004 International Conference on Ion Exchange
at Churchill College, Cambridge UK. The
proposal and selection of Michael Sadler who is a member of
the IEX2004 Organising Committee was made without his knowledge,
and was sprung upon him as a surprise at the award ceremony.
Professor Höll is a Diploma Engineer from the
University of Karlsruhe and Dr Engineer and now Professor
at The Karlsruhe Nuclear Research Centre lecturing in Fundamentals
of Sorption Processes and Ion Exchange for Water Treatment.
His main areas of interest are in ion exchange, adsorption
and soil/ground remediation and his many research achievements
over the years have included:
- The development of a non-polluting ion exchange process
for partial demineralisation of water using CO2
as regenerant, the CARIX process There are now eight full
scale plant in Germany.
- Investigations into the removal of heavy metals and other
inorganic trace contaminants from raw water, drinking water
and waste streams using ion exchange which have resulted
in the development of practical applications.
- Other heavy metal removal and separation research including
parametric pumping with pH variation and novel precipitation
systems.
- Development of adsorbtion and ion exchange materials and
processes for heavy metal and organic compounds including
magnetic separation processes.
Details of much of his work in these topics and others is published
in 70 articles in scientific journals, 60 conference publications,
reports of the Karlsruhe Research Centre and contributions to
books. In addition he has 25 patents in these areas.
Among his wide range of international activities in the development
and promotion of ion exchange technology one may note co-operative
programmes with Universities and Research Establishments in
China, Australia, Russia, Turkey, Brazil, Romania and Taiwan.
His contribution to the science has been recognised by an
award from German Fachgruppe Wasserchemie (Association of
Water Chemistry).
Professor Höll has been a member
of the SCI for many years and is a prolific contributor to
SCI Conferences, particularly the IEX conferences. In IEX
2004 alone he contributed to 6 papers based on current work
at the University of Karlsruhe.
Michael Sadler is a Chartered Chemist having obtained
his Membership of the Royal Society of Chemistry by examination
from the College of Advanced Technology at Bristol. He is
now a Fellow of the Society and Member of the British Nuclear
Energy Society. He has been associated all his life with the
UK power industry and as a Research Officer at the CEGB South
West of England Regional Scientific Services Laboratory in
Portishead he began work in the study of ultra-pure water
by ion exchange, later becoming Group Leader in a team specialising
in the condensate polishing (CP) in nuclear power plants.
This team carried out many investigations on CP plants in
the UK and internationally. In association with EPRI in the
USA they were responsible for laying down standards and making
recommendations for the design of condensate polishing units
world wide. He carried out the first in-depth studies on triple
resin systems at Doel PWR and at Fawley oil fired power station
in the UK. He also worked in association with Kennicott in
the development of Conesep and evaluated the first installation
at Aghada in Ireland.
Mike is recognised as a world expert in the performance of
ion exchange resins in condensate polishing. After leaving
the CEGB shortly before privatisation he has consulted for
a number of international organisations, companies and utilities
and maintains his association with EPRI. During his long career
he has authored or co-authored over 25 papers and other publications
in his specialist area, and a number of EPRI reports as well
as many other reports and presentations to international conferences
and meetings worldwide. In addition he has carried out training
courses in many countries.
Mike's service to the SCI has also been long and distinguished.
He served for many years on the Separation Sciences and Technology
Group Committee and was the Secretary for a considerable time.
He has been associated with the organisation
of a number of IEX conferences, being chairman of the organising
committee in 1996. He is also well known for organising the
popular and successful series of one day meetings dealing
with high purity water from 1886 to 1997. Further meetings
in this area are now being planned.
Professor Arup K. Sengupta graduated in chemical engineering
from Jadavpur University, India, and gained his PhD from the
University of Houston in the USA. He is currently .C. Rossin
Professor and Chairperson, Department Civil and Environmental
Engineering and Professor, Chemical Engineering Department
at Lehigh University, Bethlehem Pennsylvania, USA where he
has been a faculty member since 1985.
Professor Sengupta has been involved with ion exchange for
over 20 years and has gained a reputation in the field of
environmental applications. Research by his teams in these
fields has gained awards from The American Waterworks Association,
the American Society of Civil Engineers, the National Science
Foundation and the Association of Environmental Engineering
and Science Professors. He has been active in publicising
and promoting ion exchange and environmental science and technology
throughout his career with over 100 publications and four
patents in topics ranging across the removal of trace toxic
metals such as Cr and As and other materials such as phosphates
and the treatment of sludges. His developments include a new
class of hybrid IX which are composites of inorganic and organic
materials.
He is a long term member of SCI and is the instigator and
Chairman of the newly formed International Committee for Ion
Exchange. The latter is an international group which is currently
being formed to promote the development and exchange of information
in ion exchange science and technology.
The Separation Science and Technology Group congratulates
this years recipients on their awards and thanks them for
their past and continuing contribution to the development
and promotion of ion exchange science in their fruitful and
varied careers.
