Abstract
) established that the adsorption process is both spontaneous and endothermic. Moreover, TACGC demonstrated sustained efficiency over five cycles of adsorption-desorption, underscoring its structural integrity and reusability. The robustness of the system was further corroborated through statistical optimization employing the Box-Behnken design. These results underscore the significant potential of TACGC as an effective and sustainable solution for Cr(vi) remediation in wastewater treatment contexts.
