Personal profile

Profile

Jixin Qiao's research is centered on development of radiochemical methods and automation techniques for determining difficult-to-measure radionuclides, and the application of anthropogenic radiotracers in environmental and oceanic studies. Her major contribution to science include: 1) Development of automated radioanalytical apparatus based on advanced flow techniques including flow injection (FI), sequential injection (SI) and lab-on-valve (LOV); 2) Method development for determining low-level radionuclides in various environmental and waste samples based on advanced mass spectrometric techniques including inductively coupled plasma mass spectrometry (ICP-MS) and accelerator mass spectrometry (AMS); 3) Pioneering oceanic tracer application using anthropogenic uranium isotopes (U-233 and U-236) in the Baltic Sea and the Arctic Ocean; 4) Application of radioactive isotopes for environmental tracer studies including soil erosion, geological dating, pollutant transport, carbon cycling, ocean circulation and climate change.

Curriculum

-     17 years expertise in the field of Nuclear and Radioanalytical Chemistry, Radioecology and Tracer Studies as well as Speciation Analysis with research focuses on:

1)       Method development for determination of artificial and natural radionuclides (135Cs, 137Cs, 233U, 236U, 238U, 234U, 235U, 99Tc, 237Np, 241Am, 243Cm, 239Pu, 240Pu, 241Pu, 232Th, 234Th, 210Po, 210Pb, 93Mo, 94Nb, 93Zr, 90Sr, 226Ra, 228Ra) in environmental, biological and radioactive waste assays and their application in radioecology studies

2)       Application of flow techniques (flow injection, sequential injection, lab-on-valve bead injection), design and assembly of flow analysis setups for rapid and automated determination of radionuclides

3)       Radioecology and tracer studies using anthropogenic radionuclides (233U, 236U, 135Cs, 137Cs, 90Sr, 99Tc, 129I, 239Pu, 240Pu, 241Am) in marine and terrestrial environment

4)       Application of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Accelerator Mass Spectrometry (AMS) in low-level radioactivity analysis

5)       Speciation analysis for radionuclide and trace elements (137Cs, 127I, 129I, 99Tc and isotopes of Pu, Th, U)

-    Leaded 1 Danish National Research Project, 6 Nordic projects and involved in 9 Danish or Nordic projects on environmental radioactivity, radioecology, geochemistry and oceanography
