Solvent Extraction Kinetics and Interfacial Phenomena

Solvent extraction is intrinsically dependent on the mass transfer to or across the interface and the chemical reaction at the interfacial region. The researchers of solvent extraction especially in the field of analytical chemistry and hydrometallurgy

From the beginning of 1980s, some effective experimental approaches based on new principles have been invented for the studies of interfacial reactions in solvent extraction systems, which included the HSS method [15,16], the two-phase stopped flow method [17], the capillary plate method [18], the reflection spectrometry [19], and the centrifugal liquid membrane (CLM) method [20].
