Fourier-transform infrared (FTIR) spectroscopy provides rapid, reliable, quantitative, and
qualitative analysis of samples in different aggregation states, ie, gases, thin films, solids …

This study aims to compare photoacoustic (FTIR–PAS), diffuse reflectance (DRIFT), and
attenuated total reflection (ATR) FTIR modalities in the wide wavenumber range from NIR …

The capabilities of temperature-monitored IR spectroscopy for studying the organic matter
and mineral composition of humic substances (HS) were tested. Temperature dependences …

Results of efficiency of obtaining humic substances (HSs) from peat in traditional alkaline
extraction (TAE) and ultrasound-assisted alkaline extraction (UAAE) are presented. The …

Humic substances (HSs) play important roles in the transport and bioavailability of
hydrophobic organic compounds (HOCs) in soils. The sorption of HOCs depends on the …

Due to the positive effect on soil structure and the influence on improving the efficiency of
plant roots nutrient uptake, humic acids (HA) are widely considered for fertilizer production …

Soil colloid is a nonnegligible factor when evaluating the environmental risk of engineered
nanoparticles (ENPs) in the groundwater. In this study, the environmental fate of an …

Humic substances (HS) are viewed as an inherent component of soil organic matter, which
plays multiple life-sustaining functions in the environment. The complexity of the molecular …

The existing techniques for lignosulfonate (LS) in humate fertilizers lack selectivity to humic
substances (HS) as the main component; they involve labor-and time-consuming sample …
