摘要: A method for selectively capturing metal ions by treating a solution conting ions of heavy metals, such as cupric ions, zinc ions, etc., at an adjusted pH value with a metal capturing agent comprising a condensation product of a higher fatty acid or derivative thereof with an excess of a polyamine, for example, a condensation product of decanoic acid and a polyamine. Heavy metal ions contained in effluents from mines and factories are selectively captured and separated according to this method.
