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

Molecules, Journal Year: 2023, Volume and Issue: 28(6), P. 2798 - 2798

Published: March 20, 2023

The introduction of selective recognition sites toward certain heavy metal ions (HMIs) is a great challenge, which has major role when the separation species with similar physicochemical features considered. In this context, ion-imprinted polymers (IIPs) developed based on principle molecular imprinting methodology, have emerged as an innovative solution. Recent advances in IIPs shown that they exhibit higher selectivity coefficients than non-imprinted ones, could support large range environmental applications starting from extraction and monitoring HMIs to their detection quantification. This review will emphasize application for removal transition (including HMIs, precious ions, radionuclides, rare earth ions) aqueous solution by critically analyzing most relevant literature studies last decade. first part review, chemical components IIPs, main ion-imprinting technologies well characterization methods used evaluate binding properties are briefly presented. second part, synthesis parameters, adsorption performance, descriptive analysis solid phase various provided.

Toxicity with heavy metals has proven to be a significant hazard several health problems linked it. Heavy bioaccumulate in living organisms, pollute the food chain, and possibly threaten of animals. Many industries, fertilizers, traffic, automobile, paint, groundwater, animal feed are sources contamination metals. Few metals, such as aluminum (Al), may eliminated by elimination processes, but other like lead (Pb), arsenic (As), cadmium (Ca) accumulate body leading chronic toxicity Even if these have no biological purpose, their toxic effects still present some form that is damaging its appropriate functioning. Cadmium (Cd) Pb negative impacts on number physiological biochemical processes when exposed sub-lethal doses. The nephrotoxic Pb, As, Cd well known, high amounts naturally occurring environmental occupational populations exposures an adverse relationship between kidney damage metal exposure. Metal determined absorbed dosage, route exposure, duration whether acute or chronic.
