Fractionation of rare earth elements in tropical soils from marine mudstone along a toposequence
Published 2025-01-01“…Increasing ∑LREEs/∑HREEs ratios (ranged from 1.5 to 3.9), δCe (ranged from 0.3 to 1.0), and δEu (ranged from 1.1 to 1.4) values were observed relative to the decreasing elevation, which was dictated by the solubility and mobility of the elements during the transportation processes, provoking the fractionation of REEs. δCe positively and significantly (p < 0.001) correlated with dithionite-citrate-carbonate extractable iron, indicating the close interactions of iron oxides and the redox chemistry of Ce. The clustering of the samples in the principal components analysis was not observed in the distinguished prevalence of total REEs, LREEs, HREEs, and REEs fractionations, demonstrating the indirect control of the general properties to the behavior of REEs in the soils derived from marine sediments.…”

Microwave-assisted selective leaching behavior of calcium from Basic Oxygen Furnace (BOF) slag with ammonium chloride solution
Published 2017-01-01“…The Basic Oxygen Furnace (BOF) slag can be potentially used in the indirect aqueous CO2 sequestration process due to the fact that it contains large amounts of basic oxides. In this study, microwave-assisted selective leaching of calcium from BOF slag with ammonium chloride solution has been investigated in order to improve the extraction efficiency of calcium ion, and reduce leaching time and the contents of impurity ions in the leachate. …”
