Heavy metal ions

Polyethyleneimine (PEI) is a novel polymer that contains multiple amine groups that are suitable for chelation with many heavy metal ions (HMI). Anchoring PEI onto the surface of a solid substrate has been widely adopted to develop adsorbent materials with the hope of combining the HMI chelating ability of PEI with the heterogeneity of the substrate.

This research was undertaken to determine the concentrations of heavy metal ions in the surface water and sediment in water bodies that receive wastewater from the Dinh Tram and Pho Noi A industrial zones. The pollution status of the heavy metal ions and their potential ecological risks were evaluated by using the potential ecological risk index (RI) and risk assessment code (RAC).

Molybdenum insertion into the dithiolene group on the 6-alkyl side-chain of molybdopterin is a highly specific process that is catalysed by the MoeA and MogA proteins in Escherichia coli. Ligation of molybdate to molybdopterin generates the molybdenum cofactor, which can be inserted directly into molybdoenzymes binding the molybdopterin form of the molybdenum cofactor,
