摘要： The present invention relates to a chemical for chelation of metal ions, which are at least bivalent, contained in water and/or water enclosed objects and separation/recovering of formed chelate; the structural formula of which is formula (I) where R in at least one of the positions shown is comprised of a group in the form of a straight or branched hydrocarbon chain having from 9 to 20 carbon atoms, and where appropriate 1-2 hetero atoms, and which is missing in other position (s); and where X in shown positions is in a group in the form of —COOH or its salt; and wherein the chemical can be a racemate, a mixture of enantiomers, or pure enantiomers or where R is missing in all four positions shown X in at least one position is —COOR, —CONHR or CH2OR or —COR or —CH2OCOR or —CH2OCONHR; and where X in the remaining positions shown is comprised of a group in the form of —COOH or its salt; and wherein the chemical can be a racemate, a mixture of enantiomers, or pure enantiomers.
