The Application of FT-IR Spectroscopy in Waste Management

Controlled Depolymerization of Cellulose Fibres Isolated from Lignocellulosic Biomass Wastes

“…Absorption bands located at 1627-1651 cm −1 were due to adsorbed water molecules [25]. Appearances of weak absorption peaks at 1429-1433 cm −1 and 1317-1372 cm −1 were assigned to bending of CH 2 cellulose [26]. Weak absorption peaks at 1162-1164 cm −1 were due to O-H bonds at C2, C3, and C5 of cellulose [25].…”

Application of Multivariate Data Analyses in Waste Management

“…Smidt et al [16] applied PCA to illustrate the influence of input materials and composting operation on humification of organic matter. Böhm et al [14] and Smidt et al [15,17] used PCA to illustrate spectral differences caused by different materials such as biowaste, manure, leftovers, straw and sewage sludge.…”

“…Diener et al [67] investigated the long-term stability of steel slags used as cover construction of a municipal solid waste landfill by means of a PCA. Smidt et al [17] used PCA to display spectral characteristics of different landfill types.…”

“…A DA on the CO2 ion current recorded during combustion was applied to illustrate the effect of CO2 treatment of MSWI bottom ash [66]. DA was also used to illustrate the spectral characteristics of leachate from landfill simulation reactors under aerobic and anaerobic conditions [17].…”

“…They applied PLS1 to predict the calorific value, total organic carbon (TOC) and respiration activity (RA4). Smidt et al [17] also developed a prediction model for the calorific value based on spectral data. Biasioli et al [58] used PLS1 to predict odour concentration from MSW composting plants based on PTR-MS.…”
