Selective Recovery Process of Lithium from Seawater Using Integrated Ion Exchange Methods

Lithium recovery from brine using a λ-MnO2/activated carbon hybrid supercapacitor system

“…This regeneration step causes environmental problems because of the acid treatment and the following step of neutralization in which a strong base is used. In addition, manganese ions in the adsorbent are dissolved out during regeneration, restricting the reuse of the adsorbents (Nishihama et al, 2011;Shi et al, 2011). Recently, in order to improve the adsorption process, several trials were reported by introducing better fabrication methods (Xiao et al, 2012(Xiao et al, , 2013, proposing a new desorption method (Ryu et al, 2013a), applying reducing agents (Intaranont et al, 2014), or using a novel adsorbent (Chitrakar et al, 2014).…”

Lithium, Vanadium and Chromium Uptake Ability ofBrassica junceafrom Lithium Mine Tailings

“…It is found in numerous appliances ranging from electric cars, electronic sets, cellular phones, and even human heart pacemakers (Kszos and Steward 2003;Nishihama et al 2011;Bardet et al 1937;Hall et al 2005). This increase in anthropogenic activities leads to a by-product referred to as lithium mine tailings.…”

Effect of chemical treatments on lithium recovery process of activated carbons

“…Although the concentration of lithium is very low about 17 ppm, but seawater contain enormous quantity of the element lithium about 260 billion tons [7,8]. From now, many researchers have studied various techniques for lithium recovery from seawater and the salt lakes, such as solvent extraction [9], membrane processes, ion exchange resins [10], co-precipatation [11], and adsorption [12,13]. Specially, the study of adsorbent has been performed with various materials, such as LiMn 2 O 4 (Lithium Manganese Oxide), which have attracted attention in lithium adsorbents from seawater because of their high selectivity [14].…”
