چکیده
In the present review, works on classes of chelating extractants for metals, compounds with several amide and carboxyl groups, azomethines, oximes, macrocyclic (crown ethers calixarenes), phenanthroline derivatives, others are systematized. This review focuses efficiency selectivity in recovery metals from industrial wastewater, soil, spent raw materials, separation metal mixtures. As a result this study, it was found that over past seven years, largest number has been devoted to extraction heavy amino acids (16 articles), azomethines oximes (12 lanthanids (15 lanthanides actinides derivatives (7 noble calixarenes (4 articles). Analysis literature showed especially effective extracting soil; thiodiglycolamides aminocalixarenes waste; compounds, actinides; lanthanides; crown radioactive strontium, rhenium technetium. The most studied parameters processes reviewed articles were distribution ratios factors. Based articles, follows chelate polydentate more efficient secondary resources compared monodentate compounds.

Participation of Chelating Metals in Carboxylation Reactions
Introduction Chelate compounds, arising out of the combination of inorganic ions with polyfunctional organic molecules, may be expected to hold great interest for investigators in widely different fields of chemistry. The stability of many such substances can be an important factor both in the manipulation of ionic equilibria and in the alteration of organic structures. In the former applicatio...
متن کاملMinding metals: tailoring multifunctional chelating agents for neurodegenerative disease.
Neurodegenerative diseases like Alzheimer's and Parkinson's disease are associated with elevated levels of iron, copper, and zinc and consequentially high levels of oxidative stress. Given the multifactorial nature of these diseases, it is becoming evident that the next generation of therapies must have multiple functions to combat multiple mechanisms of disease progression. Metal-chelating age...
متن کاملEvaluation of extractants for estimation of the phytoavailable trace metals in soils.
Despite its environmental (and financial) importance, there is no agreement in the literature as to which extractant most accurately estimates the phytoavailability of trace metals in soils. A large data set was taken from the literature, and the effectiveness of various extractants to predict the phytoavailability of Cd, Zn, Ni, Cu, and Pb examined across a range of soil types and contaminatio...
متن کاملThe Interaction between Metals and Chelating Agents in Mammalian Spermatozoa
Several studies have been made on the bacteriostatic and fungicidal properties of oxine (8-hydroxyquinoline) and other chelating agents, and it has been suggested that they might act, in part at least, by depriving cells of essential trace metals (Albert, 1951; Martell & Calvin, 1952). In an attempt to determine the trace element requirements of mammalian spermatozoa, White (1955) investigated ...
متن کاملMobilization of heavy metals by newer, therapeutically useful chelating agents.
Four chelating agents that have been used most commonly for the treatment of humans intoxicated with lead, mercury, arsenic or other heavy metals and metalloids are reviewed as to their advantages, disadvantages, metabolism and specificity. Of these, CaNa2EDTA and dimercaprol (British anti-lewisite, BAL) are becoming outmoded and can be expected to be replaced by meso-2,3-dimercaptosuccinic aci...
