“…Although the R 2 values of Langmuir and Freundlich adsorption isotherm models were nearly close to each other, the Langmuir model better fits DNA adsorption due to the approximately same qmax values of the experimental study and the Langmuir model (Table 1). Furthermore, the R L value of the Langmuir model makes DNA adsorption favorable and DNA adsorption is exothermic according to the B T value of the Temkin isotherm [39] …”

In this work, the magnetic cellulose acetate butyrate beads (mCABs) were prepared and then, their surfaces were modified with [(3‐Aminopropyl) triethoxysilane)] (APTES) solution to generate amine groups (−NH2) as a ligand for DNA adsorption in the aqueous solution. After the surface modification, the −NH2 functionalized mCABs (N−mCABs) were characterized with Fourier Transform Infrared Spectroscopy (FTIR), scanning electron microscope (SEM), and energy dispersive X‐ray (EDX) analysis. The optimum pH value of DNA adsorption was observed at pH 4 and at this point, the N−mCABs adsorbed 4.27 mg/g DNA at room temperature (RT). The maximum adsorbed amount of DNA was calculated as 5.24 mg/g and the DNA adsorption was exothermic; furthermore, DNA adsorption was monolayer and the Langmuir adsorption model was more fitted than the Freunclich isotherm model due to the regression coefficient (R2), and the qmax values of the Langmuir model. According to reusability studies, the prepared adsorbent protected its stability and the adsorption capacity after the 5 consecutive adsorption, desorption, and regeneration cycles.
