Humic acids (HAs) are natural organic polymers that are widely distributed in terrestrial soils,
natural water, and sediments. Due to their excellent physical and chemical properties, HAs …

Humic substances (HSs) occupy 80% of organic matter in soil and have been widely applied
for soil remediation agents, potential battery materials, and adsorbents. Since the HS …

Agricultural practices such as successive cropping and irrational fertilization have led to a
steady decline in soil fertility in many regions. Humic acids (HAs) are a type of effective …

The hydrothermal humification technology provides a novel route for the preparation of
artificial humic substances (A-HS), while the mechanism underlying the hydrothermal …

Humic substance is vital for soil fertility and has wide applications such as soil remediation
agents, organic fertilizer and adsorbents. The results of pH effect on artificial humic acids …

Humification is an environmentally important process that converts organic matter and/or
pollutants into structurally refractory substances through various catalytic mechanisms …

Food waste is a challenging biomass resource due to its high moisture content, low calorific
value, and complex composition. Natural humification of animal and plant residues is highly …

This study introduces a cost-effective, mild thermal abiotic humification method for producing
highly humified artificial humic acids (AHAs) from lignin-rich biogas digestate. Derived from …

A novel preparation protocol for synthetic, look-a-like humic substances (ie, fulvic and humic
acids) simulating geochemical processes through hydrothermal reaction is presented, with …

The utilization of biomass as a raw material and production of hydrothermal humic acid
(HHA) through hydrothermal method using hydrochar as an intermediate product is a …
