The Carl Hanson Medal is awarded jointly by SCI and DECHEMA, based in Germany. It is presented during the International Solvent Extraction Conference (ISEC). The medal is seen as a life-time award to recognise scientists and engineers working in the general field of solvent extraction science and technology and is administered on behalf of SCI and DECHEMA by the International Committee for Solvent Extraction.
At the recent ISEC meeting held in Würzburg, Germany the Carl Hanson medal was awarded to Emeritus Professor Yizhak Marcus of the Hebrew University in Jerusalem. For over 50 years Professor Marcus has been involved in solvent extraction research providing a significant influence on the progress of the fundamental understanding of the physical chemistry of this technology. His main contributions were in the fields of thermodynamics, separation methods, coordination chemistry in solution, selective solvation of ions and physico-chemical aspects of ion exchange and solvent extraction.
He is a prolific author with over 300 publications and is probably best known for one of the first definitive books on the topic, Ion Exchange and Solvent Extraction of Metal Complexes co-authored with Steven Kertes and published in 1969 which was essential reading at that time and is still sometimes referred to as 'The Bible' for those working in these fields. Professor Marcus is still an active contributor on topics concerning solvation and for scientists interested in the properties of ions in solution his monographs: Ion Solvation (1985); Ion Properties (1997) and Properties of Solvents (1998) will provide valuable reading.
