Enhanced activated persulfate oxidation of

In this paper, an enhanced activated persulfate oxidation of CIP using a lowgrade titanium ore was tested with SLPSMF and SSLPSMF systems, in order to identify the influence of the irradiation source on the type, quantity, and stability of the CIP transformation products; samples along the experiment were analyzed by LCQTOFMS/MS Based on the TPs tentative identification, the Basalt samples containing ore grains of homogeneous, stoichiometric titanomagnetite (45 mol% ulvöspinel) were used to measure the diffusion coefficient and activation energy of titanium in titanomagnetite The values were obtained by means of combined ore microscopic observations, electron microprobe studies and magnetic measurementsCalculation of diffusion coefficient and activation Because sensitivity needs for many applications are not severe, they can be accomplished using an approximately 6 mg {sup 252}Cf neutron activation analysis facility The SRTC {sup 252}Cf facility continues to support applied research programs at SRTC as well as other SRS programs for environmental and waste more » management customersDETECTION AND ANALYSIS OF A TITANIUM ORE
