“…It usually takes about 1 week to complete a measurement period, and sometimes even more than 10 days. At the same time, the alpha-energy values of 239 Pu (5.16, 5.14 MeV) and 240 Pu (5.17, 5.12 MeV) are very close, and this is a great challenge to the energy resolution (at least 25 keV) of the current ion-implanted passivated planar silicon detector [ 72 ], leading to the fact that only the total activity of 239+240 Pu can be measured. Beata Varga et al [ 73 ] used alpha spectroscopy to measure the activity of 239+240 Pu of grass samples in the hilly area of Budapest as 0.024 ± 0.01 Bq·kg −1 (fresh samples), with the MDA of 0.02 Bq·kg −1 .…”

Artificial long-lived radionuclides such as 90Sr and 239,240Pu have been long released into the environment by human nuclear activities, which have a profound impact on the ecological environment. It is of great significance to monitor the concentration of these radionuclides for environmental safety. This paper summarizes and critically discusses the separation and measurement methods for ultra-trace determination of 90Sr, 239Pu, and 240Pu in the environment. After selecting the measurement method, it is necessary to consider the decontamination of the interference from matrix elements and the key elements, and this involves the choice of the separation method. Measurement methods include both radiometric methods and non-radiometric methods. Radiometric methods, including alpha spectroscopy, liquid scintillation spectrometry, etc., are commonly used methods for measuring 239+240Pu and 90Sr. Mass spectrometry, as the representative of non-radiometric measurement methods, has been regarded as the most promising analytical method due to its high absolute sensitivity, low detection limit, and relatively short sample-analysis time. Through the comparison of various measurement methods, the future development trend of radionuclide measurement is prospected in this review. The fully automatic and rapid analysis method is a highlight. The new mass spectrometer with ultra-high sensitivity shows strong analytical capabilities for extremely low concentrations of 90Sr, 239Pu, and 240Pu, and it is expected to develop determination methods with higher sensitivity and lower detection limit.

“…In another work, plutonium, which is an important contaminant of emerging concern (CEC) for radioactive waste, was determined in environmental water samples by ICP-MS/MS. 51 Sample preparation included pre-concentration by co-precipitation with Ti(OH) 3 after Pu( iii ) oxidation by NaNO 2 , and matrix separation on a TEVA® resin column. The resulting matrix still contained Ti 3+ , and the use of 0.74 L min −1 and 0.37 L min −1 of nebulizer and dilution gas flow rates, respectively, was necessary to run these samples (Table 2).…”

Emulsion templating is at the forefront of producing a wide array of porous materials that offers interconnected porous structure, easy permeability, homogeneous flow-through, high diffusion rates, convective mass transfer, and direct accessibility to interact with atoms/ions/molecules throughout the exterior and interior of the bulk. These interesting features together with easily available ingredients, facile preparation methods, flexible pore-size tuning protocols, controlled surface modification strategies, good physicochemical and dimensional stability, lightweight, convenient processing and subsequent recovery, superior pollutants remediation/monitoring performance, and decent recyclability underscore the benchmark potential of the emulsion-templated porous materials in large-scale practical environmental applications. To this end, many research breakthroughs in emulsion templating technique witnessed by the recent achievements have been widely unfolded and currently being extensively explored to address many of the environmental challenges. Taking into account the burgeoning progress of the emulsion-templated porous materials in the environmental field, this review article provides a conceptual overview of emulsions and emulsion templating technique, sums up the general procedures to design and fabricate many state-of-the-art emulsion-templated porous materials, and presents a critical overview of their marked momentum in adsorption, separation, disinfection, catalysis/degradation, capture, and sensing of the inorganic, organic and biological contaminants in water and air.
