Recovery of lithium ions from salt lake brine is becoming more important because of the rapid increase in projected demand for lithium resources. N,N-bis(2-ethylhexyl)acetamide (N523) is a newly developed extract ant that presents good lithium extraction ability and selectivity. In this study, the kinetics and mechanism of lithium ion extraction with N523 in kerosene at 298.15 K were investigated using the rising single drop method. Results showed that the extraction process is controlled by diffusion and that the chemical reaction occurs at the interfacial area. (C) 2015 Elsevier B.V. All rights reserved.
