摘要: Abstract Heavy metals in the laboratory wasteliquid can be recovered as stable and economic ferrite by process. The spectrum of X-ray absorption near edge structure (XANES) specifically shows that 92% Cr(OH) 3 8% CrCl 2 original are converted to 70% Cr O 30% precipitates concentrations total chromium, lead zinc also dropped from 383,000, 20.9 277 ppb, respectively, lower than effluent standards Environmental Protection Administration (EPA) Taiwan. XRD (X-ray diffraction) analysis chromium is achieved at pH > 9. On other hand, XANES spectra situ experiment show there were 52% Fe 4 precipitates.
