Due to the fact, that microplastics are a global environmental problem, new ways for their removal from water, soil and air need be developed. New materials in combination with easy implement technologies microplastic come into focus of scientific studies engineering, especially application water resources. In our comparative case study, effects composition temperature on agglomeration-fixation reaction using organosilanes were examined. We compared biologically treated municipal wastewater,...
Fluorescent staining of microplastics as a detection method is consistently gaining importance in research, it fast, easy to use, and requires low technical effort. In this study, complete procedure was developed, from sample collection processing detection, measure with cost time requirements. The developed tested by measuring the effluent German wastewater treatment plant over period one year. results show that process especially well suited investigate temporal variations microplastic...
Wastewater from plastic manufacturing or processing industries is often highly polluted with microplastics (MPs) and high levels of oxidizable organic matter, which results in a chemical oxygen demand (COD). When industrial wastewater enters streams, the microplastic load burden for municipal treatment plants (WWTPs), as they are not sufficiently removed. To prevent MP entering WWTPs, an upstream prevention method essential. This paper presents pilot-scale plant study removal COD that was...

The KArlsruhe TRItium Neutrino (KATRIN) experiment will measure the absolute mass scale of neutrinos with a sensitivity mν = 200 meV/c2 by high-precision spectroscopy close to tritium β-decay endpoint at 18.6 keV. Its Windowless Gaseous Tritium Source (WGTS) is source high intensity (1011 s−1) and stability, where high-purity molecular 30 K circulated in closed loop yearly throughput 10 kg. To limit systematic effects column density has be stabilized 10−3 level. This requires extensive...
Abstract We report on the results of ESR and ENDOR investigations H centres in KF, NaCl, KCl, RbCl, NaBr, KBr, RbBr. New were obtained for RbCl. The g ‐factor proton hyperfine constant all mentioned alkali halides have been measured precisely. In addition to previously published KCl RbCl we well resolved spectra NaCl KBr. All superhyperfine quadrupole constants known at present are given compared.
Wastewater treatment plants (WWTPs) have been identified as important point sources of micropollutants and microplastics into the environment. Existing fourth cleaning steps are designed to remove dissolved micropollutants, however do not target dispersed solids such microplastics. Therefore, ability an Advanced Oxidation Process (AOP) Granular Activated Carbon (GAC) in parallel serial connection was investigated determined. The pilot were operated at municipal WWTP Landau, Germany, a...
Microplastics (MPs) that are ubiquitous in aquatic environments and industrial wastewater streams have been identified as key hotspots of MP contamination. It is significantly more effective to remove MPs at these points before they enter municipal streams. This study an environmental assessment a novel pilot plant for the removal chemical oxygen demand (COD) from with high contamination plastics manufacturer Germany. based on physical–chemical agglomeration–fixation by organosilanes. Formed...
Wastewater treatment plants (WWTPs) are important point sources for microplastics (MPs) in the environment. For effective mitigation measures and regulations, it is to monitor their release into environment understand level of MPs WWTP effluents based on different technologies. In this study, we compare MP levels three municipal WWTPs which each use a concept: conventional three-stage WWTP, one with an additional fourth cleaning stage using powdered activated carbon, two-stage utilizing...
We have recorded Raman spectra for all hydrogen isotopologues, using a CW Nd:YVO4 laser (5 W output power at 532 nm) and high-throughput (f/1.8) spectrograph coupled to Peltier-cooled (200 K) CCD-array detector (512 × 2048 pixels). A (static) gas cell was used in measurements. investigated (i) "pure" fillings of the homonuclear isotopologues H2, D2, T2; (ii) equilibrated binary H2 + T2, D2 thus providing heteronuclear HD, HT, DT controlled manner; (iii) general mixtures containing varying...
AbstractThe gas circulation loop LOOPINO has been set up and commissioned at Tritium Laboratory Karlsruhe (TLK) to perform Raman measurements of circulating tritium mixtures under conditions similar the inner system neutrino-mass experiment KATRIN, which is currently construction. A custom-made interface used connect containing measurement cell, located inside a glove box, with setup standing on outside. sample (purity > 95 %, 20 kPa total pressure) was circulated in for more than three...
Micropollutants have been increasingly detected at low concentrations in surface waters and may harmful effects on humans, organisms, the environment. As wastewater treatment plants are one of main sources micropollutants, conventional methods (mainly to three cleaning stages) must be improved through an advanced (fourth) stage. The optimal fourth stage should determined based not only removal efficiencies but also a holistic sustainability assessment that further considers process’s...
As surfaces are exposed to tritium, they will inevitably accumulate it, leading the tritium memory effect. In order reduce this effect, e.g. in analytic systems, decontamination methods required. UV/ozone is known be an efficient method, but its fundamental mechanism not well known. a dedicated UHV-compatible experiment, method investigated systematically. This work focuses on pressure dependent ozone production and depletion rates, as equilibrium concentration. All three properties showed...

In this paper, we summarize recent achievements in further development on technique, and various applications which it used TLK. Further, show that has evolved as a versatile, highly accurate key method quantitative complementing portfolio analytic techniques
