Summary:An orthogonal test design was applied to confirm the optimum condition for H 2 TiO 3 –lithium adsorbent preparation and Li + adsorption. Extraction and adsorption mechanism and cycle performance were studied. The verified optimal condition is confirmed as the Li + concentration, adsorption temperature, molar ratio of Li/Ti, reaction, and pre-calcination temperature are 4.0 g L −1 , 60 °C, 2.2, and 650 and 25 °C, respectively. Under the optimal condition, the adsorptive capacity reaches 57.8 mg g −1 . Adsorptive capacity of the adsorbent maintains in 5 cycles, typically 25–30 mg g −1 .
