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 …

The intervention of human in phosphorus pool seems to be a vicious circle. The rapid
population growth leads to the global food shortage, which leads to the massive use of …

In this paper, we have successfully prepared porous magnetic biochar with excellent surface
area and recovery rate using corn stalks (CS) and waste iron (WI) as precursors. Notably, in …

Nano zero-valent iron (nZVI), as a high-efficiency adsorbent for heavy metals, often suffers
being oxidized and assembling together due to small size and super reactivity, further …

Waste activated sludge (WAS), the major by-product of wastewater treatment plants, has
been hugely produced with the increase of wastewater treatment capacity. Anaerobic …

Humic acid (HA) exerts a variety of significant environmental and geochemical influences on
the soils, sediments and aqueous environments. The interaction with metal ions induces …

This study addresses the research gap in understanding the differences in straw
decomposition and variations in humic substances (HS) extracted from various treatment …

Humic acid can effectively bind several metals and is regarded as a promising soil washing
agent. Previous studies indicate that carboxylic groups dominate metal binding to humic …

A novel functional colloid-like magnetic biochar (Col-L-MBC) with high dispersibility is
prepared by the one-step method with the prepared porous biochar as the skeleton. Notably …

It is of great significance to develop an adsorbent with fast adsorption rate for gold ions to
ensure high adsorption capacity and selectivity. Here, we report two humic acid modified …
