Monitoring of natural radionuclides in soils as a tool for precision farming - methodical aspects,al profiles. The latter proved a well mixing of soil material in the uppermost 30 cm by ploughing. A mathematical procedure for the consideration of soil moisture and the determination of the “information depth” is presented and lead to good agreement between field and laboratory data.Dislocation 发表于 2025-3-28 22:27:16

A method to measure arsenic readily released to pore waters from uranium mill tailings, .n .losed .ystems (EPICS). The method employs a gentle leaching solution that, except for its arsenic (As) concentration, is identical to the neutralized raffinate that contacts the tailings. Prior to implementation, the experimental design and mathematical approach were verified in geochemical mod外星人 发表于 2025-3-29 08:28:35
Impact of humic acid on the uranium migration in the environment,. Applying laser-induced photoacoustic spectroscopy a qualitative spectroscopic proof for the reduction of U(VI) to U(IV) by humic acid was obtained. By column experiments it was found that humic acid influences the transport of both, U(IV) and U(VI). In presence of humic acid both redox species mig顽固 发表于 2025-3-29 13:15:25
,Uranium speciation in two Freital mine tailing samples: EXAFS, µ-XRD, and µ-XRF results,ractions, EXAFS, µ-XRD, and µ-XRF reveal two major U pools. The first with a relatively high potential mobility was identified as U(VI) sorbed to layer silicates by inner-sphere complexation; the second pool is represented by the relatively insoluble U(IV) minerals pitchblende and coffinite, and byMODE 发表于 2025-3-29 17:40:39

Advanced Investigations of Unconventional Uranium and Thorium Deposits by ,-EDXRF Analysis,ce (EDXRF) technique that allows the high resolution, ., multi-element determination at the microscopic scale (10 to 100µm). EDXRF analysis is fast and useful for the identification of unconventional uranium and thorium deposits, the localisation of primary uranium and thorium minerals as well as se
