Organic complexants include EDTA, DTPA and aminoethyl diphosphonate.

Non-complexing buffers must be used when testing organometallic compounds .

The complexing phosphonic acids may be used alone or in a mixture.

The complexing groups are in particular xanthate, xanthide or dithiocarbamate groups.

The products made according to the invention are particularly useful as complex formers.

A filter media (49) is composed of wicking fibers which are impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents.

The invention also relates to lanthanide complexes resulting from said complexing agents.

Further, said chrome-free passivating solution may comprise one or more complexing agents.

The peptides possess a helical structure and are bound by a plurality of complexing agents.

The preferred non-persistent complexing agents are hydroxamic acids, and the most preferred is acetohydroxamic acid.

Citric acid and aminotriacetic acid were the auxiliary complexants.

Other suitable complexing agents are dendrimers, especially polyamidoamine dendrimers (which are cationic).

chelating or complexing agents referred to in point 3 of CMC 1 in Part II of Annex II

The amphiphiles are useful for the formation of vesicles and micelles and for use as complexants and surfactants.

These hydroxyalkylaminocarboxylic acids are useful as complexing agents for alkaline earth and heavy metal ions.
