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.

• University degree in chemistry, specialization in radiochemistry or geochemistry
• Good knowledge of radiochemistry and inorganic chemistry
• Basic knowledge of analytical and spectroscopic standard procedures
• Basics of chemical model calculations
• Experience in working with glove boxes and in handling open radioactive substances
• General knowledge of sorption processes and final disposal safety research
• Good written and spoken English skills
• High level of self-motivation, strong communication skills, ability to work in a team
• Initial professional experience is desirable.
