![]() ![]() The method was determined to be accurate and effective using real water samples and CRM. The results showed that the sorbent has good selectivity in the presence of competing ions. Adsorption was a spontaneous and endothermic process based on the obtained thermodynamic properties such as ΔG°, ΔH°, and ΔS°. ![]() The Langmuir isotherm and the pseudo-second-order model fit the experimental data better. The adsorption capacity for Cu(II) ions was 43.67 mg/g and the removal efficiency was 84.72 percent. Optimum conditions for Cu(II) adsorption were determined as adsorbent dose 0.04 g, pH 5.0, contact time 120 min, and beginning concentration of 30 mg/L in the adsorption process. The structure of the adsorbent was characterized by FTIR, XRD, SEM, EDX, and TEM analysis. (3-chloropropoxy) anthracene-9,10-dione was synthesized as a new, sustainable, and environmentally friendly adsorbent for magnetic solid-phase extraction of Cu(II) from aqueous solutions.
