Times Cited Count：14 Percentile：55.36(Instruments & Instrumentation)Polarizance of a reflection-type polarizer made with a synthetic mica (fluorophlogopite) single crystal was evaluated at the photon energy of 880 eV by means of the rotating-analyzer method in conjunction with the evaluation of the degree of linear polarization of the insertion beamline, SPring-8 BL23SU, featuring an APPLE-2 type variably polarizing undulator. When the undulator was tuned to the horizontal linear polarization mode, the maximum reflectances for s- and p-polarization for a symmetric Bragg reflection of synthetic mica(002) were 2.6% and 0.013%, respectively, at incident angles of near 45
. Our analysis based on the rotating-analyzer method gave the polarizance of the polarizer of at least 0.997 
0.002 and the degree of linear polarization of 0.993 0.004 in the linear polarization mode.

Times Cited Count：8 Percentile：50.24(Instruments & Instrumentation)This study examined removal of cadmium from solution by two materials with high sorptivity for cadmium: a synthetic mica named Na-4 mica and an apatite. At an initial Cd concentration of 1
10
M and a starting pH of 3, the distribution coefficient of Na-4 mica for Cd (8.410
ml/g) was one order of mgnitude of higher than that of apatite (8.210
ml/g). On the other thand, micro-PIXE anaysis for a mixture of equal mass of Na-4 mica and apatite contacted with Cd solution under the same conditions revealed that Cd was selectively taken up by the apatite in the mixture, while Cd was not detected on the Na-4 mica in the mixture. This result by micro-PIXE analysis is not what is expected from the above distribution coefficient values of Na-4 mica and apatite. This result can be explained by irreversibility of the uptake and the difference in kinetics of the uptake by the Na-4 mica and apatite.
