ABSTRACT The extraction of lithium from the waste of used batteries is going to be necessary due to the limited resources of lithium. One of the most common methods to extract is liquid–liquid extraction with an organic solvent. In this study, Bis(2-ethylhexyl) phosphoric acid (D2EHPA) solvent is used for liquid–liquid extraction of lithium-ion in a T-shaped microchannel. Lithium chloride solution has been used as a dispersed phase and, D2EHPA solvent with sunflower oil has been unitized as a continuous phase. The effect of some parameters, such as the flow rate of the continuous phase and the amount of the consumed solvent on the time of slug formation process, slug length and, extraction percentage has been investigated. Results showed that the time of the slug formation decreases by increasing the flow rate of the continuous phase. Also, it found that with increasing the pH of the aqueous phase by 36% resulted in a 15% reduction in the length of the slug. With an increase of 67% of the consumed solvent, the slug length increases by about 16%. By increasing the amount of the consumed solvent, the slug length increases. In continuation, with increasing the slug length, extraction percentage increases.

ABSTRACT Depending upon charge and chemical affinity, interplay between resistances of membrane (Rmem) and membrane–solution interface (RHT) may lead to preferential transport of an ion. Here, intermittent in-situ electrochemical impedance spectroscopy (EIS) was done during electrodriven transport (radiotracer based) to analyze the transport selectivity of Cs+ over Na+ in different membranes. Preference of the membranes for Cs+ was reflected in the time-dependent Nyquist plots itself. Bode plot analysis also indicated dominant Cs+ transport in terms of phase and frequency shift in crown ether (DB21C7) based membrane. In Cs+ selective polymer incluion membranes, irrespective of carrier, RHT contributed majorly to overall resistance. However, time dependence of RHT/Rmem was carrier as well as ion dependent. Interestingly, for nonselective ionic carrier, RHT/Rmem was majorly close to 1 and a reverese transport order than previous membranes were obtained. A higher Na+ transport (than Cs+) was also obtained for DB21C7 loaded Nafion, where, due to ion templating effect, Rmem was the governing factor. EIS spectral nature of a mixed feed solution follows that of the most preferred ion, thus suggesting that EIS can be used to study prospective real-life systems and can be used as a significant tool in designing ion-selective membranes.
