Figure 4

Silver XANES K-Edge spectra of sludges and the 6 Ag references used for the PCA. Where ANP = aerobic sludge from the AgNP dosed SBR; NNP = anaerobic sludge from the AgNP treatment; NI = anaerobic sludge dosed with Ag+; AI = aerobic sludge from the SBR dosed with Ag+; Ag-thio = Ag thiosulfate complex; and, Ag-GSH = Ag glutathione complex. For spectra of the control sludge (collected from the SBR that was not spiked with Ag) see Figure SI.4.
