The use of NTA for lead phytoextraction from soil from a battery recycling site

Phytoextraction of Cu, Zn, and Pb Enhanced by Chelators with Vetiver (Vetiveria zizanioides): Hydroponic and Pot Experiments

“…From their sequential extraction results, Pb distribution fraction in soil after chelator addition followed the sequence exchangeable > organic matter > iron oxides. 5 mmol/kg of EDTA increased the loosely bound Pb [17]. Another study demonstrated that the mobility and bioavailability of heavy metals in soils were correlated with soil texture, surface area, cation exchange capacity, and soil pH [18].…”

Potential of Taraxacum mongolicum Hand-Mazz for accelerating phytoextraction of cadmium in combination with eco-friendly amendments

“…Thus, some natural and/or synthetic chelators were used to increase uptake of heavy metals from soil thus achieving higher removal rates. Some amendments such as EDTA, EDDS, EGTA, NTA and organic acids have been studied for their abilities to mobilize metals and increase metal accumulation in different plant species [5][6][7][8]. Unfortunately, most of these chelating agents showed some negative effects on soil environment such as elevated toxicity to both plants and soil microorganisms, and the potential risk of leaching into ground water [7,9].…”

Evaluation of the sequestering ability of different complexones towards Ag+ ion

“…Anderegg et al [18] found for the same species log K (AgL) = 6.50 and 2.50 [18] at the same ionic strength but in KNO 3 . In addition, the authors found the presence of the Ag 2 (EDTA) 2− and Ag 2 (EDTA) 2 6− species. From the comparison of the data, it can be concluded that the difference in the complex formation constants can be attributed to the different cation of the supporting electrolyte as well as the presence of the Ag 2 (EDTA) 2 − and Ag 2 (EDTA) 2 6 − species in the speciation scheme of Anderegg et al [18].…”

“…For example, they are used as additives to cleaning agents, as bleach stabilizers and Ca 2+ and Mg 2+ binders; in textile and paper industries to bind heavy metal ions that can affect the industrial processes; in agriculture as sources of nitrogen in fertilizers; as chelating therapy agents in biology and medicine; in the remediation processes of polluted soils and sediments as chelators of toxic metal ions, etc [1][2][3][4][5][6][7][8][9], and for these reasons they are the topic of important reviews (e.g. in refs.…”
