| Abstract: | The dicarboxylic and oxycarboxylic acids known as complexing agents for metal ions under the conditions when the amount of
metal ions exceeds that in metal complexes, act as precipitants for metal ions. The completeness of precipitation, depends
on the kind of metal and organic acid, pH and the concentrations of substances. The abundance of metals in metal finishing
industry enables to use such precipitation for regeneration and decontamination of the complexing agents containing solutions. |
