Degradation of TCE by TEOS Coated nZVI in the Presence of Cu(II) for Groundwater Remediation

Figure 4

EDS analysis of nanofer ZVI after the experimental test, pH = 6, T = 21^°C. (a) TCE concentration (1 mM) and Cu(II) concentration (1 mM): iron, oxygen, carbon, copper, copper, carbon, oxygen, iron, copper, and carbon. (b) Nanofer ZVI in deionized water; the peaks appear in the following sequence (left to right): iron, oxygen, copper, chlorine, copper, chorine, and iron.
