In this work, surface characteristics of chemically treated activated carbons (ACs) were studied for lithium ion in aqueous solution. From the results, it was found that the chemical treatments introduced functional groups onto the ACs surfaces. The amount of lithium ion recovery was enhanced by basic treatments. Also, we characterized lithium ion adsorption-desorption efficiency. The lithium adsorption-desorption efficiency exhibited good stability after five adsorption?desorption cycles. Consequently, it could be concluded that lithium ion recovery behaviors are greatly influenced by the basic characteristics of AC surfaces, resulting in enhanced electron acceptor-donor interaction at interfaces.
