Abstract

The presence of heavy metals in industrial wastewater poses a serious challenge due to their accumulative nature and potential to disrupt ecosystem balance. One widely applied approach to address this issue is the adsorption process using activated carbon, which is known for its high porosity and large surface area. However, the main limitation of this method lies in the decrease of adsorption capacity after repeated cycles of use, thus requiring regeneration through desorption. The selection of desorbing agents and the management strategy of the resulting desorption effluents are important aspects to ensure the sustainability of adsorbent application. This study aims to analyze the effectiveness of activated carbon desorption using HCl and NaOH solutions at various concentrations, their effect on the morphological structure of the adsorbent, the effectiveness of repeated adsorption, and the neutralization requirements of the desorption wastewater. The methods used include adsorption–desorption processes, morphological analysis with SEM-EDX, measurement of metal content using AAS, and pH neutralization testing of the liquid waste. The results showed that HCl was more effective than NaOH, with desorption percentages reaching 49% at a concentration of 0.25 M, while NaOH was around 25%. Treatment with HCl produced more open and homogeneous pore structures and was able to maintain adsorption capacity up to 90.2% in the second cycle, much higher than NaOH at 35.2%. In terms of wastewater treatment, HCl solutions were easier to neutralize with lower base volume requirements, while NaOH required a larger volume of acid. Keywords: activated carbon, desorption, repeated adsorption, heavy metals, wastewater.
