The main aim of this study was the application of excitation-emission fluorescence matrices (EEMs) combined with two decomposition methods: parallel factor analysis (PARAFAC) and nonnegative matrix factorization (NMF) to study the interaction mechanisms between humic acids (HAs) and Zn(II) over a wide concentration range (0-50 mg·dm-3). The influence of HA properties on Zn(II) complexation was ...
To estimate the order of importance of factors affecting the stability and maturation of compost, cow feces and maize stalks were co-composted at different aeration rates “AR” (22, 44 and 66 L kg-1 DM . min-1) of C/N ratios (16, 19, 22), and moisture contents “MC” (60 %, 65 %, 70 %). A composting process was monitored by physical and chemical methods. The thermophilic phase with all treatments ...
7 [1] Soil organic matter (SOM) is a primary reservoir of terrestrial sulfur (S), but its role in 8 the global S cycle remains poorly understood. We examine S speciation by X-ray 9 absorption near-edge structure (XANES) spectroscopy to describe S species behavior 10 during SOM decomposition. Sulfur species in SOM were best represented by organic 11 sulfide, sulfoxide, sulfonate, and sulfate. Th...
