Printed circuit boards (PCBs) are a secondary source for the extraction of precious metals,
such as gold (Au), silver (Ag), platinum (Pt), palladium (Pd), etc. Thiosulfate and glycine …

The influence of different pH conditions and simulated inter-root environmental solutions on
the release behavior of heavy metals (Cu, Pb, and Zn) from contaminated soils was …

Direct revegetation is a promising strategy for phytostabilization of metal smelting slag sites.
Slag comes into direct contact with root exudates when slag sites undergo direct …

Root exudate is a major source of soil organic matter and can significantly affect arsenic (As)
migration and transformation in paddy soils. Citric acid is the main component of rice root …

High levels of manganese (Mn) and other heavy metals from electrolytic manganese residue
(EMR) stockpiled would be released into the environment under natural conditions. A batch …

Reducing highly toxic and mobile Cr (VI) to environmentally less hazardous Cr (III) is vital
research for remediating Cr-contaminated soil. In this study, a UV/EKR system, which …

Huge amounts of Pb smelting residues were generally stored in landfills or unprocessed
worldwide, and thus demand novel strategies to implement clean production. In this paper …

Enhancing the uptake and enrichment of heavy metals in plants is one of the important
means to strengthen phytoremediation. In the present study, citric acid (CA), tartaric acid …

Abstract In this study, Mg/Fe-doped biochar (MFDB) was prepared using the impregnation
pyrolysis method, and its preparation was optimized using response surface methodology …
