Physicochemical and spectroscopic characteristics of dissolved organic matter extracted from municipal solid waste (MSW) and their influence on the landfill biological stability

Effect of inoculation with a microbial consortium that degrades organic acids on the composting efficiency of food waste

“…In addition to the aforementioned three peaks, the EEM spectra of DOM extracted from the AC and C samples were also characterized by the peaks a, b and c. According to He et al . (2011b), peak a is representative of fulvic acid‐like material and peaks b and c are associated with humic acid‐like fluorophores. Compared with the AC and C samples, peaks T1, T2, T3, a and b disappeared in the EEM spectra of DOM extracted from the Inoculation compost, whereas the humic‐like peak c became the primary fluorescence peak.…”

The influence of flue gas desulphurization gypsum additive on characteristics and evolution of humic substance during co-composting of dairy manure and sugarcane pressmud

“…The UV-vis absorption could offer some useful information on HS composition, because in the UV region, p-p ⁄ electron in the phenolic arenes, benzoic acids and polycyclic hydrocarbons with two or more rings could transit (He et al, 2011). The 254-280 nm related to lignin and quinine moieties.…”

Structural transformation study of water-extractable organic matter during the industrial composting of cattle manure

“…To date, WEOM analysis has mainly focused on conventional parameters, such as dissolved organic carbon (DOC) concentration and the ratio of DOC to dissolved organic nitrogen [4,[6][7][8]. Little work has been done to identify the compositions and structural characteristics of WEOM extracted from cattle manure during composting.…”

“…Indices derived from UV-visible (UV-vis), Fourier transform infrared (FTIR), and fluorescence spectra have proven useful in investigating the structural characteristics of organic matter [8,9]. As a rapid and economical method, UV spectrometric analysis at certain wavelengths, such as 280 nm, obtains data that are positively correlated with aromatic carbon content and molecular weight, and provides information on the molecular structure of WEOM [10].…”
