Hydrocolloid-Stabilized Magnetite for Efficient Removal of Radioactive Phosphates
Figure 5
X-ray photoelectron spectroscopy of (a) pure GK, showing the major oxygen (1s) and carbon (1s) peaks, and (b) GK/M nanocomposite. The spectrum together with spectra of Fe (2P3/2, 2P1/2) (inset) is presented. The peak at ~715 eV corresponds to Fe 2P3/2 of Fe3+ and the small peak at ~723 eV corresponds to Fe 2P1/2, confirming the formation of magnetite.
