In this way, REE could be separated from major elements and were concentrated by a factor of about 60. The recovery of REE was more than 95% using this method. Four ultramafic rock reference materials, PCC-1 (USGS), JP-1 (GSJ), DZE-1, DZE-2 (IGGE) and one new proficiency testing...
Approximately 3 mg (wtmeasured) of each synthesized sample (wtsynthesized) was dissolved in the minimum volume of concentrated HNO3, and then deionized water was added until the final volume of 10 mL (Vf) was reached. Exactly 100 µL (V1) of this solution, mixed of 100 µL of ...
HNO3/H2SO4作为硝化试剂反应示例 硝酸与硫酸组成的混酸是比硝酸更强的硝化剂,根据底物活性的高低可以使用普通的硝酸或发烟硝酸,这个方法可以顺利地得到多硝基取代的产物。 A 5-L three-necked flask fitted with an all-glass addition funnel and two condensersis c...
Analysing the pole figures in Fig. 7, an increasing scattering of the crystal orientations is observed after Gd addition, while the Gd-free alloy shows a more concentrated orientation of the Al phase. Gd‑rich intermetallics The low Gd solubility in the α-Al phase (lower than 0.2 mass...
