FT-IR spectrogram of the related samples before mercury adsorption: (a) SCO, SCO2V, SCO4V and the related cross-linker CO and modifiers 2-VP as well as 4-VP, (b) SCO, SCOA and the related cross-linker CO and modifier AEMA, (c) SCO, SCOE and the related cross-linker CO and modifier EMAB, (d) SCO, SCODM and the related cross-linker CO and modifier DMAEMA (when mass of modifiers was 5% of sulfur mass, corresponding samples were chosen for FT-IR analysis).
