— The formation of LiF x /MgF x O y and the influence of surface and interface on devices performances are The in situ inter atomic diffusion of Fluorine F and Oxygen O at the LiF x /Mg interface is An impressive efficiency of>21% with LiF x /MgF x O y is achieved which has over 6% absolutely
— Experimental data on the sorption extraction of uranium from fluorine containing solutions on different types of modern ion exchange absorbers and structures in order to improve the technological schemes for reprocessing wastes from radiochemical production are presented The primary technological relations are studied and the optimal
Results showed that performance in terms of recovery differed between the extraction methods for different PFAS; different extraction methods resulted in different EOF concentrations indicating that the choice of extraction method is important for target PFAS and EOF analysis Since the detection of per and polyfluoroalkyl substances PFAS in
— A novel extractant 2 ethylhexyl Bis 2 ethylhexyl phosphinate EHBEHP abbreviated as B was synthesized for the extraction of Cerium IV Ce IV and fluorine F I from nitric acid HNO 3 effects of HNO 3 concentration extractant concentration F I concentration and the temperature on the Ce IV and F I extraction
Total fluorine TF refers to the total amount of organic and inorganic fluorine measured directly in a sample no sample extraction while extractable organofluorine EOF refers to isolating organofluorine from the sample matrix while removing inorganic fluorine typically fluoride or its complexes with Al 3 3 4 from the extract
Abstract Cerium Ce usually exists in minerals with accompany of multiple elements such as fluorine F To develop technologies and provide theoretical foundations for comprehensive recovery of Ce and F the extraction and stripping process of Ce Ⅳ by primary amine N1923 in sulfuric acid medium containing fluorine was investigated
