Evaluation of a Novel Water Treatment Residual Nanoparticles as a Sorbent for Arsenic Removal

Figure 2

The X-ray diffraction (XRD) analyses of WTR nanoparticles. The XRD results ascertained amorphous iron, aluminum (hydr)oxides, and silicon oxide dominating all nWTR, with no apparent crystalline iron-Al (hydr)oxides.
