Recent advances in the detection and removal of heavy metal ions using functionalized layered double hydroxides: a review

Abstract

Recent advances in the detection and removal of heavy metal ions using layered double hydroxide-based nanosensors and nanosorbents are summarized.

Versatile MXenes as electrochemical sensors for heavy metal ions and phenolic moiety-containing industrial chemicals: recent development and prospects

“…The literature depicts several reports on HMI detection using inorganic material-modified WEs, micro-, macro-, and nanoparticle-based biosensors to detect HMI, functionalized layered double hydroxides, and several others. 142,162,163 Hence, the literature lacks a review MXene-based sensors for HMIs. MXene-based sensors are excellent candidates for sensing HMIs, as their multi-layered structure generally comprises elements that possess high-affinity properties to HMIs.…”

Tuning Sensing Efficacy of Oligo(phenylenevinylene) Based Chromogenic Probes: Effect of Alkyl Substituents on Metal Ion Detection at Micelle‐Water Interface

“…This broadening might be attributed to the heavy metal effect of Hg 2 + ions and the aggregation of metal ion-bound probe molecules within the reaction medium. [47] Further, we have compared EPR spectra of Cu 2 + [in form of Cu(NO 3 ) 2 ] before and after addition of compound 2 (Figure 9a). In prescence ligand (here compound 2), the EPR peak experienced a shift in magnetic field value, which might be due to changes in the ligand field strength or the nature of the ligands coordinating with the Cu 2 + ion.…”

Naphthalimide‐based fluorescent probe for Hg2+ detection and imaging in living cells and zebrafish

“…Low concentrations of heavy metals can be very harmful to human health, including nervous system disorders, organ disease, stunted growth, cancer and even death [1][2][3]. Mercury, as a highly toxic metal, long-term exposure to it can cause seriously adverse effects on the kidney, brain, physiological organs and immune system [4][5][6].…”
