75% part-time

Organizational unit

Institute for Nuclear Waste Disposal (INE)

Job description

The PhD is conducted in the frame of a collaborative project with several German universities and research institutions. Your area of responsibility essentially includes:

• Literature study to identify relevant C-14-containing organic molecules and optimization of analytical methods
• Conducting sorption experiments in clay systems with variation of key parameters
• Conducting experiments in clay model systems to evaluate the effect of various cations in the interlayer, the charge distribution or the absence of a permanent layer charge in the interlayers of the clay minerals on retention processes
• Conducting sorption experiments in cement systems with cement paste and pure cement phases
• Conducting the experiments as a function of time, solid-liquid ratio, concentration of C-14 concentration, and ionic strength
• Comparing the data obtained with previous studies on the sorption of organic molecules to cement
• Publication of the results.
