Ion-Imprinted Polymeric Materials for Selective Adsorption of Heavy Metal Ions from Aqueous Solution [PDF]

open access: yesMolecules, 2023
The introduction of selective recognition sites toward certain heavy metal ions (HMIs) is a great challenge, which has a major role when the separation of species with similar physicochemical features is considered.

Diffusion Behaviour of Trivalent Metal Ions in Aqueous Solutions [PDF]

open access: yesChemistry & Chemical Technology, 2011
Trivalent metal ions have a relevant impact on different kinds of industry; for example, indium(III) and europium(III) ions are of practical importance in the development of new semiconductors and luminescent probes, respectively. Transport properties of ions and salts in aqueous solutions are important physico-chemical parameters allowing a better ...
