XRD patterns were recorded at room temperature on a Siemens Kristalloflex D 500 diffractometer (Cu Ka radiation, Ni filter, 40 kV, 30 mA.; 2θ = 5-60°, 0.05° step size, and 3 s count time); simultaneous TGA/DTA were performed on a TA Instruments STD 2960 with alumina crucibles and alumina powder reference; SEM was performed on a JEOL JSM-6300V scanning electron microscope with the LINK GEM light-window energy dispersive spectrometer.
12. sln is volume of solution (25 mL). 50 ppm solutions were in contact with SOMS at room temperature for 12 h, followed by chemical analyses of the solutions.
