| Abstract: | Primary amine N1923 plus kerosene is used for extracting Cr(VI) in a bench-scale experiment. The extraction undertaken in acidic solution involves reactions producing complex, i.e., (RNH3)_(2) CrO_(4). The effects of factors such as initial acidity of aqueous phase, concentration of primary amine N1923, and temperature on the distribution ratio were investigated. Problems with the occurrence of third phase were studied, the interference eliminated. |
