Abstract
The elution behavior of copper(��) and iron(��) ions by phenol sulfonic acid(PSA) as an eluent on chelating resin, Amberlite IRC-718 have been investigated. When copper(��) and iron(��) solutions were adsorbed on the resin and eluted with various concentration of PSA, two peaks of each ion were appeared in the elution curve. These two peak areas were changed according to the PSA concentration. Using these phenomena, the stability constants of complex formation between the two ions and PSA were calculated. The values are 7.0 for copper(II) and $4.5{\times}10^4$ for iron(II), respectively.
