| Abstract: | The extraction of nickelous from sodium sulphat solution with P538 at 40℃ is studied. The proposed extraction mechanism is as follows: . The apparent extraction equilibrium constant is calculated to be 87. 57.This paper also diseuases the relation between the elitribution ratio D and the solubility paramter δd of different diluents at 40℃, such as kerosene, benzene, cyclohexane, hexcane and toluene, that is as follows: 1gD= -0. 247δ+ 4. 062δd - 17. 410. |
