“…During the filtration process, electrostatic interactions between the membrane and ions can directly affect the mass transfer of ions [111,202,203]. Ions with higher hydration energy or larger ion radius in the solution are more likely to be trapped by the membrane [29,204]. Owing to its special pore size and charge ability, the rejection of multivalent ions by an NF membrane is higher than that of monovalent ions.…”

Rapid developments in the electric industry have promoted an increasing demand for lithium resources. Lithium in salt lake brines has emerged as the main source for industrial lithium extraction, owing to its low cost and extensive reserves. The effective separation of Mg 2? and Li ? is critical to achieving high recovery efficiency and purity of the final lithium product. This paper summarizes Mg 2? /Li ? separation materials and methods in the field of lithium recovery from salt lake brines. The review begins with an introduction to the global distribution and demand for lithium resources, followed by a description of the materials used in various separation techniques, including precipitation, adsorption, solvent extraction, nanofiltration membrane, electrodialysis, and electrochemical methods. A comparison, analysis, and outlook of such methods are comprehensively discussed in terms of principles, mechanisms, synthesis/operation, development, and industrial applications. We conclude with a presentation of challenges and insights into the future directions of lithium extraction from salt lake brines. A combination of the advantages of various materials is the most logical step toward developing novel methods for extracting lithium from brines with high separation selectivity, stability, low cost, and environmentally friendly characteristics.

“…NF can also be an interesting solution to selectively demineralize salted water to produce isotonic waters (Oumar Correspondence concerning this article should be addressed to S. Déon at sebastien.deon@univ-fcomte.fr. Anne et al, 4 Pontié et al 5 ) and for the treatment of food ingredients solutions such as seafood aromas concentration (Walha et al 6 ) or peptides solutions concentration (Bourseau et al 7 ). Prediction of separation performances is an important way of improvement and a predictive model could be a very useful tool for process development and optimization, or for membranes characterization with the aim to provide help to end-users for the selection of commercial membranes for water desalination (Pontié et al 8 ).…”

The two‐dimensional pore and polarization transport model to describe mixtures separation by nanofiltration: Model validation

et al. 2011

Nanofiltration is a membrane process which is used to separate charged molecules such as ions. Even if this process is well known, there is no mean to predict the performances of a given separation. The aim of this paper is to present a two-dimensional model called ''pore and polarization transport model'' which includes all the steps of the ions transfer. The membrane transport modeling is based on the classical onedimensional vision coupling the Donnan, steric, and dielectric exclusions with the extended Nernst-Planck transport equation. But the originality of this study comes from the modeling of the transport through the polarization layer. The model used in this study is an improvement of the previous version, which includes an electrical gradient within the polarization layer allowing the prediction of polarization layer establishment even for ionic mixtures. The purpose of this article is to describe the model accurately before validating it with various ionic solutions.

“…In the groundnut basin of Senegal, high fluoride and salinity concentrations are found in groundwater [1]. Fluoride concentrations above 1.5 mg/L are known to cause dental fluorosis while those greater than 4 mg/L can cause crippling skeletal fluorosis [1] [2]. In Senegal, fluorosis is among the most common diseases due to water quality [3].…”

Consumption of safe drinking water is essential to human health. The excess of certain elements in drinking water causes health problem for people consuming these waters. In Senegal, the excessive levels of fluoride and salts found in the groundnut basin cause public health problem such as dental and/or skeletal fluorosis. Thus, the treatment of such waters is essential before consumption to prevent health problems. For a partial removal of fluoride and salinity, we tested the performance of two commercial nanofiltration membranes namely TFC-SR3 and SelRO MPF-34 at laboratory scale. The results showed that TFC-SR3 membrane was very efficient with rejection rates of 83%-96% for fluoride ions and 89%-96% for salinity. For SelRo MPF-34 membrane, retention rates of 25%-52% were obtained for fluoride ions and 24%-60% for the salinity.
