摘要：

A model for computer simulation of extraction-stripping systems is presented in which the extraction equilibrium is computed by very precise smoothing spline functions. Extraction of copper from acidic sulfate solutions by the pure fraction of 2-hydroxy-5-nonylbenzaldehyde is discussed. Extraction of copper decreases in the following order: systems with cross-current flow >systems with combined flow ã classical systems with sequential stages of extraction and stripping. For each process, an appropriate extraction-stripping flow sheet with various combinations of extraction and stripping stages and various solvent flows can be selected. © 1990, American Chemical Society.
