Assessment of EDTA-enhanced electrokinetic removal of metal(loid)s from phosphate mine tailings

Supramolecular Pd@methioine-EDTA-chitosan nanocomposite: an effective and recyclable bio-based and eco-friendly catalyst for the green Heck cross-coupling reaction under mild conditions

“…[99][100][101] On the other hand, ethylenediaminetetraacetic acid (EDTA) has been applied as a supramolecular chelating and ion exchange agent for several metal ions in many preceding publications. [102][103][104][105] EDTA has also outstanding ability to act as a low-cost and non-toxic cross-linker for creating strong bonds with organic nucleophilic functional groups. [106][107][108] Hence, EDTA has been recently used as a linker to afford several nanocatalytic systems, such as chitosan-EDTA for Knoevenagel condensation reaction, 109 chitosan-EDTA-cellulose network for Hantzsch esters and 4Hpyrans synthesis, 80,84 L-asparagine-EDTA-amide silica-coated MNPs for 3,4-dihydropyrimidin-2(1H)-ones synthesis, 110 and diamide-diacid-bridged PMO for the cascade oxidation of benzyl alcohols/Knoevenagel condensation, 111 and Pd@ASP-EDTA-CS for HCR.…”
