摘要：Lithium-rich bauxite contains abundant associated lithium oxide resources and represents a largely untapped source of lithium. During the Bayer process, approximately 80 % of lithium enters the sodium aluminate solution. However, research on the efficient extraction of lithium from sodium aluminate solutions remains limited due to the lack of low-cost and high-efficiency technologies. In this study, a novel activated carbon-supported aluminum-based lithium-ion adsorbent (C-Li/Al-LDHs) was developed, and its lithium adsorption performance in sodium aluminate solution was systematically investigated. The results show that C-Li/Al-LDHs can effectively adsorb lithium from the solution. The adsorption efficiency increased with longer adsorption time, higher adsorbent dosage, elevated adsorption temperature, and higher lithium concentration. The key factors affecting the adsorption process were systematically examined, and a maximum lithium adsorption efficiency of 77.09 % was achieved under optimal conditions: an adsorbent dosage of 15 g/L, an adsorption time of 2 h, a water bath temperature of 70 degrees C, and a lithium concentration of 80 mg/L.
