Abstract. Treating lithium in aqueous solutions through adsorption is crucial due to the rising demand for lithium in batteries and renewable energy. This method offers a cost-effective and efficient way to capture lithium ions. Effective treatment methods are essential to mitigating these environmental risks. To address this concern, separation technologies like adsorption have been utilized to remove lithium from solutions with minimal concentrations. This study specifically investigates the removal of residual lithium from a synthesized solution using aluminum hydroxide Al(OH)3 as the adsorbent. The research examines the impact of adsorbent dosage, lithium concentration, and pH on residual lithium removal. Results underscore the substantial influence of pH on residual lithium efficiency, with optimal removal observed at pH 4.5, an adsorbent dosage of 1150 mg/L, and a lithium concentration of 1150 mg/L, achieving an 89% removal rate. The utilization of Al(OH)3for lithium adsorption has been demonstrated as an efficient technique for for recovering lithium from synthesis solutions. The process followed a pseudo-first-order kinetic model (R² = 0.917) and fit the Langmuir isotherm model (R² = 0.91). These findings contribute to a better understanding of Al(OH)3 adsorption behavior and provide perspectives on the most favorable operational parameters for effective lithium recovery.
