| Abstract: | Liquid-liquid extraction of cobalt(II) and manganese(II) were carried out from sulphate solution with Cyanex 302 in toluene as the diluent. Cobalt(II) was quantitatively extracted at pH 7.0-7.5 in the presence of 1.0 M ammonium sulphate with 7.5 x 10-3M Cyanex 302 while the extraction of manganese(II) was quantitatives at pH 8.5-9.5 in the presence of 0.1 M ammonium sulphate with 5 x 10-3M Cyanex 302. Cobalt(II) from the organic phase was stripped with 1.0 M hydrochloric acid while manganese(II)was stripped with 1.0 M sulphuric acid. Both metals were separated from complex mixtures of several metals. These methods were extended for the determination of cobalt and manganese in real samples. |
