Synthesis of novel Chitosan-Tannic acid adsorbent for removal of Aluminum (III) from wastewater: characterisation, kinetics, equilibrium isotherms and thermodynamic studies
This study efficiently removed aluminum from commercial wastewater by using different doses of the novel chitosan-tannic acid (CT1, CT3, and CT6) bio-materials adsorbent. The Al3+ ions were determined using 797 VA anodic linear sweep voltammetry Computrace. The research examined the adsorption kinetics, adsorption isotherms, and the effect of the solution flow rate. The Freundlich isotherms precisely represented the adsorption results, with a maximum adsorption capacity of adsorbent was 684.93 mg/g. The experimental results showed that the adsorption of aluminum was maximum when solution concentrations were up to 200 mg/L. The findings indicated that the chitosan-tannic acid biomaterials primarily followed a complexation-adsorption method, exhibiting maximum adsorption capacity at pH 6.5. The study investigated the BET adsorption–desorption isotherm and evaluated the adsorption efficacy of adsorbents. Consequently, this novel, sustainable chitosan-tannic acid complex might be a successful bio-adsorbent for removing aluminum metal ions from wastewater solutions.
