摘要
Citric acid partial esters corresponding to the following general formula IMAGE (I) in which R1, R2 and R3 represent hydrogen or a straight-chain or branched C4-C20 alkyl radical or a metal atom, with the proviso that at least one but at most two of the substituents R1, R2 and R3 represent such an alkyl radical, or mixtures of the citric acid partial esters corresponding to general formula (I), are used for the extraction of iron from aqueous solutions.
