Biography

Louis van der Ham was born on June 16th 1960 in Weerselo. He studied Chemistry at the HTS and Chemical Engineering at the University of Twente. During his study he was a board member of the student association ‘Alembic’ and was one of the organizers of the study tour to England. He graduated Cum Laude in January 1986. In the same month he started his PhD research at the group ‘Proceskunde’ of Prof.dr.ir. W.P.M. van Swaaij at the same university.

  Ionic Liquid-Based Process Development for Cobalt Recovery from Aqueous Streams

  Using the ionic liquid [P8888 +][Oleate-], liquid-liquid extraction has been studied to recover Co2+ from water. Extractionregeneration experiments were followed during five consecutive cycles with Na2CO3(aq) as regeneration solution. Over 99% of Co2+ was extracted and using 0.7-1 M Na2CO3(aq) the extracted Co2+ was recovered for 99% in the form of CoCO3(s). Co2+ transfer shifted from ion-pair extraction in the first cycle to ion-exchange in the successive cycles. Thus, the measurement of a single extraction–regeneration cycle is not sufficient to perceive conclusive information about the steady-state conditions of the process. In the context of the feasibility of the technology, four key aspects are addressed: extraction efficiency, recovery of the IL, loss o.. View More»
