Biosorbents for Removing Hazardous Metals and Metalloids.

Article Abstract

Biosorbents for remediating aquatic environmental media polluted with hazardous heavy metals and metalloids such as Pb(II), Cr(VI), Sb(III and V), and As(III and V) were prepared from lignin waste, orange and apple juice residues, seaweed and persimmon and grape wastes using simple and cheap methods. A lignophenol gel such as lignocatechol gel was prepared by immobilizing the catechol functional groups onto lignin from sawdust, while lignosulfonate gel was prepared directly from waste liquor generated during pulp production. These gels effectively removed Pb(II). Orange and apple juice residues, which are rich in pectic acid, were easily converted using alkali (e.g., calcium hydroxide) into biosorbents that effectively removed Pb(II). These materials also effectively removed Sb(III and V) and As(III and V) when these were preloaded with multi-valent metal ions such as Zr(IV) and Fe(III). Similar biosorbents were prepared from seaweed waste, which is rich in alginic acid. Other biosorbents, which effectively removed Cr(VI), were prepared by simply treating persimmon and grape wastes with concentrated sulfuric acid.

The present study introduces a minimalistic and cost-effective approach to synthesising Gold nanoparticles (AuNPs) using aqueous leaf extracts of Andrographis paniculata. In this synthesis, bioactive metabolites in the leaf extract act as reducing agents, converting Au³⁺ ions to metallic Au⁰, while proteins in the extract form a stabilising layer around the nanoparticles to prevent agglomeration and maintain particle size stability. The synthesised AuNPs were systematically characterised using a range of analytical techniques.

Enrichment and MALDI-TOF-MS/MS Analysis of Phosphatidylinositol Bisphosphates in Brain Tissue.

Anal Biochem

December 2024

Dept. of Gerontology (AgeTech-Service Convergence Major), Graduate School of East-West Medical Science, Kyung Hee University, Yongin, Republic of Korea. Electronic address:

Triazolium α-cyclodextrin click cluster-magnetic agarose bead conjugate (CCC-MAB) was used to enrich phosphatidylinositol bisphosphates in brain tissue. The enriched sample was phosphate-methylated and analyzed by MALDI-TOF-MS/MS in positive ion mode. CCC-MAB effectively removed weak-binding interferences from the phosphoinositide extract and improved the signal-to-noise ratio.

The modification of Pt surfaces with organic compounds like melamine enhances oxygen reduction reaction activity and catalyst durability. Through first-principles free energy calculations utilizing thermodynamic integration and finite-temperature molecular dynamics, enhanced by machine learning force fields for efficient sampling of nanosecond-scale interfacial water fluctuations and incorporating corrections to accurately reproduce first-principles free energies, we demonstrate that melamine destabilizes OH adsorbates, facilitating their removal and enhancing catalytic activity. Unlike alloys, where OH destabilization is driven by changes in electronic structure and surface strain, melamine disrupts hydrogen bonding between OH and interfacial water.

Enrichment of a heterotrophic nitrifying and aerobic denitrifying bacterial consortium: Microbial community succession and nitrogen removal characteristics and mechanisms.

Bioresour Technol

Department of Ecology, College of Life Science and Technology, Jinan University, Guangzhou 510632, Guangdong, China. Electronic address:

This study cultivated a bacterial consortium (S60) from landfill leachate that exhibited effective heterotrophic nitrification and aerobic denitrification (HN-AD) properties. Under aerobic conditions, the removal of NH-N reached 100 % when the S60 consortium utilised NH-N either as the sole nitrogen source or in combination with NO-N and NO-N. Optimal HN-AD performance was achieved with sodium acetate as a carbon source and a pH of 7.
