Definition from
Alconox, Inc.:
These are negatively charged or oxygen containing molecules that react with positively charged metal ions to form a stable complex. They have multiple locations in the molecule to react with multiple positive charges that may be present on multivalent metal ions that have more than one positive charge on them. An example of a chelating agent is EDTA, ethylene diamine tetraacetic acid. EDTA has four acetic acid groups giving it a potential for four negatively charged acetates to bond with up to four positively charged sites on metal ions with multiple positive charges, such as calcium which has two (2) positive charges associated with it.
Example sentences:
EDTA is a versatile chelating agent. It can form four or six bonds with a metal ion, and it forms chelates with both transition-metal ions and main-group ions. EDTA is frequently used in soaps and detergents, because it forms a complexes with calcium and magnesium ions. (University of Wisconsin)
HIDS shows superior performance as a chelating agent; high thermal stability, high solubility in concentrated alkaline solutions and low corrosion. (NIPPON SHOKUBAI CO.)
The extraction parameters were the type and concentration of chelating agent and the duration of extraction time. All the extractions that involved chelating agents were carried out at pH 7.0. The heavy metal extraction efficiencies of chelating agents were compared to those of HNO3, CaCl2, and deionized water. (ASCE)

helirajući agens
Mislim da je odgovor dimekaprol (na pitanje iz rečenice koju sam postavila kao primer).
Nema baš mnogo o ovome na srpskom jeziku.

helatni reagens
Ima dosta primera na Internetu, bilo kao 'helatni reagens' ili 'helatni agens', ali se po GBK propozicijama ne mogu ponuditi dva odgovora.
chelating agent - reagens koji izaziva stvaranje helatnih jedinjenja.
Ref. E-S Hemijsko-tehnološki rečniki (A. Mihailidi, M. Mihailidi).
