Characteristics and mechanisms of hexavalent chromium removal by biochar from sugar beet tailing.
Removal of Cr(VI) from aqueous solutions using biochar from sugar beet tailing (SBT) was investigated as a function of pH, contact time, and biochar mass via batch experiments. The surfaceExpand

Metabolic adaptations to arsenic-induced oxidative stress in Pteris vittata L and Pteris ensiformis L
Abstract This study examined the metabolic adaptations of Pteris vittata L, an arsenic hyperaccumulator, under arsenic stress as compared to Pteris ensiformis, a non-arsenic hyperaccumulator. BothExpand

Simultaneous immobilization of lead and atrazine in contaminated soils using dairy-manure biochar.
Biochar produced from waste biomass is increasingly being recognized as a green, cost-effective amendment for environmental remediation. This work was to determine the ability of biochar toExpand

Arsenic speciation and distribution in an arsenic hyperaccumulating plant.
Arsenic-contaminated soil is one of the major arsenic sources for drinking water. Phytoremediation, an emerging, plant-based technology for the removal of toxic contaminants from soil and water, hasExpand

Removal of arsenic by magnetic biochar prepared from pinewood and natural hematite.
There is a need for the development of low-cost adsorbents to removal arsenic (As) from aqueous solutions. In this work, a magnetic biochar was synthesized by pyrolyzing a mixture ofExpand

Antioxidant responses of hyper-accumulator and sensitive fern species to arsenic.
Plant species capable of hyper-accumulating heavy metals are of considerable interest for phytoremediation, and differ in their ability to accumulate metals from the environment. This work aims toExpand

Mechanisms of metal sorption by biochars: Biochar characteristics and modifications.
Biochar produced by thermal decomposition of biomass under oxygen-limited conditions has received increasing attention as a cost-effective sorbent to treat metal-contaminated waters. However, thereExpand

Phytoremediation of an Arsenic-Contaminated Site Using Pteris vittata L.: A Two-Year Study
A field study was conducted to determine the efficiency of Chinese brake fern (Pteris vittata L.), an arsenic hyperaccumulator, on removal of arsenic from soil at an arsenic- contaminated site.Expand

Manganese oxide-modified biochars: preparation, characterization, and sorption of arsenate and lead.
This work explored two modification methods to improve biochar's ability to sorb arsenic (As) and lead (Pb). In one, pine wood feedstock was pyrolyzed in the presence of MnCl2·4H2O (MPB) and in theExpand
