Adsorption of Fe-modified peanut shell biochar for Pb(II) in mixed Pb(II), Cu(II), Ni(II) solutions [PDF]

Scientific Reports
A Fe-modified black peanut shell biochar (Fe@BC) was fabricated using FeCl3 as a magnetic modifier, its sorption for Pb(II) in mixed Pb(II), Cu(II), Ni(II) solutions was examined. It was showed that Fe@BC had better adsorption for Pb(II).

Developmental Toxicity and Thyroid-Disrupting Effects of Combined Exposure to Pb(II) and ²¹⁰Pb(II) in Zebrafish Embryos [PDF]

Toxics
The toxicity of radioactive metals arises from both chemical toxicity and radiotoxicity. 210Pb(II) is a long-lived radionuclide in the decay chain of natural uranium series 238U and exhibits extremely high toxicity.

Microbial Pb(ii) Precipitation: the Role of Biosorption as a Pb(ii) Removal Mechanism

Chemical Engineering Transactions, 2021
The role of a metabolically independent lead removal mechanism in an industrially obtained lead-precipitating consortium was investigated. Cultures were prepared under anaerobic conditions for 24 hours in batch reactors starting with 20 g L-1 tryptone ...

A novel green synthesized magnetic biochar from white tea residue for the removal of Pb(II) and Cd(II) from aqueous solution: Regeneration and sorption mechanism.

Environmental Pollution, 2023
A novel biochar-based magnetic nanocomposite (GSMB) was prepared from white tea waste via green synthesis method. The sorption properties and regeneration of GSMB were studied using Pb(II) and Cd(II) to better understand its ability in heavy metal ...

Arabidopsis ACBP1 overexpressors are Pb(II)-tolerant and accumulate Pb(II) [PDF]

Plant Signaling & Behavior, 2008
In our recent paper in the Plant Journal, we demonstrated that Arabidopsis thaliana acyl-CoA-binding protein ACBP1 binds lead [Pb(II)], its mRNA is induced by Pb(II)-treatment and transgenic Arabidopsis overexpressing ACBP1 are conferred Pb(II) tolerance and accumulate Pb(II).
