Extraction of cobalt(II) with 7-(1-decenyl)-8-quinolinol (HRql) into chloroform was examined. The best cobalt extraction occurs in the pH region 5.5–9. In this region several other cations are extracted. The values of Kex and pH0.5 for cobalt extraction were found to be −8.6 and 3.19 respectively. The composition of the extracted complex was found to be Co(Rql)3. Cobalt is poorly reextracted from Co-HRql complex into the aqueous phase, the best results were obtained using HCl as a stripping agent.
