Property of H2TiO3 Type Ion-exchangers and Extraction of Lithium from Brine of Natural Gas Wells
Abstract:
The ion-exchangers of H2TiO3 type for Li+ were prepared from TiO2 and Li2CO3(or LiOH), followed by calcinating at 400~800℃. The ion-exchangers showed an unusual high selectivity for Li+ in mixtures of alkali metal and alkaline earth metal ions. The exchange capacity for Li+ was 25.34 mg/g. The selectivity order was Li+>>Mg2+ > Ca2+ > Na+,K+. Being applied in brine of a local natural gas well, an exchange rate and elution rate for Li+ up to 97% and 98%, respectively, were achieved.
