Spray-drying assisted layer-structured H2TiO3 ion sieve synthesis and lithium adsorption performance
文献摘要：
A spray-drying assisted solid-state method to prepare spherical layer-structured H2TiO3 ion sieve(LSTIS)particles is reported herein.The effects of synthesis parameters(calcination temperature,calcination time,and the lithium-titanium molar ratio)on adsorption-desorption performance(the delithiation ratio,titanium dissolution loss,and the adsorption capacity)were investigated.The as-prepared LSTIS exhibited an equilibrium adsorption capacity of 30.08 mg·g-1(average of 25.85 mg·g-1 over 5 cycles)and ultra-low titanium dissolution loss of less than 0.12％(average of 0.086％over 5 cycles).The LSTIS showed excellent selectivity toward Li+in Na+,K+,Mg2+,and Ca2+coexisting saline solutions where its adsorption capacity reached 27.45 mg·g-1 and the separation factors of Li+over the coexisting cations exceeded 100.The data suggests that the LSTIS is promising to competitively enrich Li+from saline solutions.
