Helmholtz Centre:        Forschungszentrum J¨¹lich
Department/Institute:         Central Institute for Engineering, Electronics and Analytics (ZEA-3)
Supervising scientist:        Dr. Volker Nischwitz
University for Registration: Karlsruhe Institute of Technology (KIT)
Research Field:         Analytical Chemistry, Particle Separation with Elemental Detection
Position:        PhD Student

Research Area:         
The project is closely related to remediation of pollutants in lakes, which is also a problem for lakes in China. A major problem for example in TaiHu is the excessive growth of micro-algae. The task of the advertised PhD project will be the development and adaption of particle separation techniques (using field flow fractionation (FFF)) online with various detectors including inductively coupled plasma mass spectrometry (ICP-MS) for elemental characterization. The developed methods will be applied for detailed characterization of the suspended particulate matter in lake water. The goals will be on the one hand a better understanding of sedimentation and re-suspension processes on availability of nutrients in the water and on the other hand the analytical evaluation and documentation of the efforts to implement novel water treatment and cleaning technology by the other partners of the project network. The hyphenation of FFF online with ICP-MS is frequently applied for nanoparticle characterization and will be extended for this project to cover natural particles from nanometer to low micrometer range.


Specific Requirements:          
The successful candidate requires an excellent background in analytical chemistry with experience in liquid separation techniques and elemental mass spectrometry combined with an interest in environmental chemistry. In addition high level English language skills are mandatory. The method development and optimization will be performed at Forschungszentrum J¨¹lich within the first part of the PhD project and afterwards the system will be applied to real world water samples from cooperation partners. Therefore, high motivation to relocate and work in Germany is required and ability to work independently. Our institute hosts several PhD students from China and other countries. The candidate is expected to provide good communication and team working skills.

Duration of stay: 3-4 years, respectively
Work Place: J¨¹lich, Germany
Earliest Start: Sept. 2017
Language Requirement:         English (fluent in speaking and writing)
