Article Abstract
The production of new cost-effective biocompatible sorbent sustainable materials, with natural origins, able to remove heavy metals from water resources is nowadays highly desirable in order to reduce pollution and increase clean water availability. In this context, self-assembled protein materials with amyloid structures seem to have a great potential as natural platform for a broader development of highly-tunable structures. In this work we show how protein particulates, a generic form of protein aggregates, with spherical micro sized shape can be used as adsorbents of Pb ions from aqueous solution. The effect of pH, ionic medium, ionic strength and temperature of the metal ion solution on the adsorption ability and affinity has been evaluated revealing the complexity of adsorption mechanisms which are the result of the balance of specific interactions with functional groups in protein structure and not specific ones common to all polypeptide chains, and possibly related to amyloid state and to modification of particulates hydration layer.

A magnetic nanocomposite adsorbent, comprised of macroporous iron oxide/manganese oxide (α-FeO/MnO), is prepared, characterized, and used for lead(II) removal from both industrial wastewater and leachate of electronic waste. The synergistic interaction between iron oxide and manganese oxide significantly enhances the adsorption performance. The surface characteristics and structural composition of the nanocomposite are examined using high-resolution transmission microscopy, X-ray spectroscopy, and Brunauer-Emmett-Teller methods.

Article Synopsis
- Heavy metal ions like thallium(I) and lead(II) are harmful environmental pollutants that pose risks to human health and ecosystems.
- The study developed innovative biosensors and paper-based assays using aptamers and an intercalating agent (berberine) for detecting these toxic metals, achieving impressive sensitivity with detection limits as low as 1.1 nM for Tl(I) and 1.6 nM for Pb(II).
- The new assays were able to effectively identify these metal ions even in contaminated river water samples, highlighting their potential for fast and cost-efficient screening methods.
Preparation and application of a new ion-imprinted polymer for nanomolar detection of mercury(II) in environmental waters.

Department of Chemistry, Neyshabur Branch, Islamic Azad University, Neyshabur, Iran.
This study introduces a novel ion-imprinted polymer for the ultrasensitive detection of mercury(II) in water. The ion-imprinted polymer was synthesized via a simple bulk polymerization process using methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the cross-linker, morpholine-4-carbodithioic acid phenyl ester as the chelating agent, and ammonium persulfate as the initiator. The electrochemical mercury(II) sensing capability of the ion-imprinted polymer was studied via the modification of a cost-effective carbon paste electrode.
