Prices start from £295.00

Registration closes on Thursday 4 July at 12.00pm

The SCI IEX and Japanese ICIE conferences are the major ion exchange events worldwide. These unique meetings provide the opportunity for manufacturing and service companies, end users, and researchers to present papers and discuss applications and developments in the theory and practice of ion exchange and adsorbents.

Tackling climate change, reversing nature loss, and achieving 'net zero' require good decision-making and engagement with complex social, economic, and environmental challenges. A revolution in the design and application of ion-exchange materials is taking place as they emerge as vital tools to meet these challenges. IEX2024 will be the focus of this pioneering work.

The conference will cover new materials, their study by surface and structural techniques, and their application in fields as varied as bioprocessing and biomanufacturing, sequestration of carbon dioxide, catalysis, and green chemistry, and in many areas of pollution control and water treatment.


Attendees will enjoy the unique environment that Homerton college provides. The College is only a few minutes’ walk from the city centre and has extensive grounds. The focal point of the College, its Victorian Gothic hall. It is within a few miles of the M11 motorway and easy access to the Cambridge train station; yet just a short walk to the historical centre.

Venue and accommodation

The conference takes place at Homerton college in Cambridge. The college boasts an impressive Victorian facade and spacious landscaped gardens create a tranquil and welcoming environment. 
En-suite accommodation can be booked by delegates attending the conference. Bedrooms will be allocated on a first come, first served basis. Accommodation can be booked for up to 3 nights or as required:
