In a process called phytoremediation, hyperaccumulating plants are used to clean up environmental contamination. Well, it just so happens that sunflowers are particularly adept at extracting radioactive metals, like the cesium-137 and strontium-90 found at Chernobyl. After the Chernobyl disaster fields of sunflowers were planted to …

Introduction. Strontium (symbol Sr, atomic no. 38) is a natural and commonly occurring alkaline earth metal (lying in group IIa, period 5, sandwiched vertically between calcium and barium). The mineral was discovered in 1790 by Adair Crawford and William Cruickshank at Strontian (Scotland).

Strontium and cesium are high-yield fission products that are present in appreciable amounts in fuel pond waters and reprocessing stream liquors. 18,19 Further, they comprise a significant fraction of the total activity deposited onto steels used for spent fuel storage and in reprocessing plants. 3 Model contamination systems were used to ...

Few studies have carried out soil washing experiments using pot experiments to simulate in situ soil washing operations, particularly for alkaline soils. This study explored the effects of multiple washing operations using pot experiments on the removal efficiencies of potentially toxic metals (PTM) from alkaline farmland soil and the …

Amaranthaceae are effective plants for cleaning soil contaminated by heavy metals and radionuclides. In this paper, Amaranthus tricolor was used to investigate the response of the plant photosynthesis to various concentration of strontium ions (0.2, 0.6, 3 and 6 mM), in order to determine the possibility of A. tricolor to remediate strontium contamination.

The Clarence Sands wash plant is made up of a H30 Feeder, a 20x8 2 Deck Rinsing Screener, two FM 200C Sand Recovery Units, a Flocculant Dosing Unit, a Rake Thickener Tank and a number of stacking conveyors.The large through-put and stockpile capacity resulted in the installation of two 26-metre radial stockpiling conveyors.

Strontium processing description from its geology mineral property to how to extract mineral from rock and placer deposit, related processing plant flow chart and layout design.

The following are the common symptoms of scaling: To clean the scale and remove it, the crystalline precipitate needs to be redissolved. The following cleaning features are needed to facillitate the redissolving: Low pH – Treating the scale with an acid will help to dissolve scale build-up. Common strong acids are sulfuric acid, hydrochloric ...

In particular, the radioactive isotopes Cesium-137 and Strontium-90, which are prominent among the radioactive elements generated in nuclear power plants, emit strong radiation, and have a very long half-life of 30 years [14], [15]. In the event of accidents like Fukushima, these hazardous substances can be released into the natural …

Washing Plants. Astec produces a variety of washing and classifying plants suited for a wide range of applications and production goals. Our expertly engineered plants help producers meet the most stringent material specifications and get the most out of their material. With complete lines of scrubbing, sand classifying, dewatering, water ...

The plants are slightly contaminated by 90Sr with the average specific activity of (3.6 ± 4.3) mBq/g, which depend on plant species, live stages and variational in different tissue.

This study investigated the distribution and accumulation of strontium (Sr) in the shoots and roots of Euphorbia macroclada (EU), Verbascum cheiranthifolium (VR), and Astragalus gummifer (AS), with respect to their potential use in phytoremediation. Plant samples and their associated soils were collected from the arid and semi-arid Keban …

Semantic Scholar extracted view of "Dynamics of Strontium and geochemically correlated elements in soil during washing remediation with eco-complaint chelators." by Z. A. Begum et al. ... TRONTIUM takes the same uptake and distribution pathways of Ca within plants; hence disturbs many secondary metabolites. In humans, it …

Plants preferentially absorb 86 Sr, resulting in high soil ... Strontium (Sr), the most abundant trace element in rocks, soil, water, and organisms, is an alkaline earth metal with an atomic number of 38. ... Cleaning: 8 ml mixture of 4N HNO 3 + 0.5N HF+2 ml of ultra-pure water:

Sand Washing Plants. McLanahan Sand Washing Plants process sand from its raw state into products that meet various specifications. The process requirements vary depending on the input and desired output, but plants typically scrub, liberate, deslime, wash, classify, decontaminate and dewater the sand, as well as process the effluent stream that results.

Sandmaster™ DP series sand wash plants feature the same industry-leading technology and benefits of the Sandmaster™ SP series. However, the dual-grade sand plant has added functionality which enables it to create two separate sand products, simultaneously. The raw sand is fed onto the coarse side of the split-deck Enduron® dewatering screen.

If contaminant diffusion into the bulk material can be effectively inhibited during reprocessing or spent fuel storage, then removal of surface bound contaminants (e.g., via chemical washing) will likely prove to be a reliable decontamination technique.

Stainless steels can become contaminated with radionuclides at nuclear sites. Their disposal as radioactive waste would be costly. If the nature of steel contamination could be understood, effective decontamination strategies could be designed and implemented during nuclear site decommissioning in an effort to release the steels from regulatory …

There was a linear relationship between the 137Cs concentration in plants and its concentration in soil only for redroot pigweed, and estimates of time required for removal of 50% of the two contaminants are 7 yr for 90Sr and 18 yr for 137Cs. A field test was conducted to determine the ability of three plant species to extract 137Cs and 90Sr …
