Chemists propose new reagents for the removal of lead from wastewater

RUDN University chemists together with colleagues from other countries have synthesized new compounds that effectively bind lead ions and can be used to remove it from wastewater and even from living organisms—that is, to play the role of an antidote for lead poisoning. The article is published in the journal Crystals. Complex compounds of lead are widely used for the synthesis of polymers and compounds necessary for the production of semiconductors, materials for nonlinear optics and ferroelectrics. The large radius of the divalent lead ion Pb (II) allows you to change the number of bound atoms, ions or molecules (ligands) from four to nine. Thus, it is possible to obtain a wide range of substances based on lead that combine organic and inorganic components in a single molecule. The widespread use of lead compounds in production leads to the accumulation of toxic waste, creating the problem of removing lead from wastewater.  Read more.....
