Lithium-based draw solute for forward osmosis to treat wastewater discharged from lithium-ion battery manufacturing
文献摘要：
As draw solute is the core element of forward osmosis(FO)technology,here Li-Bet-Tf2N synthesized from a customized ionic liquid betainium bis(trifluoro-methylsulfonyl)imide([Hbet][Tf2N])and Li2CO3 recov-ered from lithium-ion battery(LIB)wastes is proposed as a novel draw solute to treat Li+-containing wastewater from LIB manufacturing through FO filtration.Having high dissociation ability and an extended structure,Li-Bet-Tf2N generates a sufficiently high osmotic pressure to drive the FO filtration efficiently along with insignificant reverse solute diffusion.Li-Bet-Tf2N produces a water flux of 21.3 L·(m2·h)-1 at 1.0 mol·L-1 against deionized water,surpassing conventional NaCl and MgCl2 draw solutes with a higher water recovery efficiency and a smaller solute loss.Li-Bet-Tf2N induces a more stable and higher water permeation flux with a 10.0％water flux decline than NaCl and MgCl2 for which the water fluxes decline 16.7％and 16.4％,respectively,during the treatment of 2000 mg·L-1 Li+-containing wastewater for 12 h.More remarkably,unlike other draw solutes which require intensive energy input and complicated processes in recycling,Li-Bet-Tf2N is easily separated from water via solvent extraction.Reproducible results are achieved with the recycled Li-Bet-Tf2N.Li-Bet-Tf2N thus demon-strates a novel class of draw solute with great potentials to treat wastewater economically.
