Therefore, it is necessary to remove them from the environment. In the current study, zeolite modified by cationic surfactant of cetylpyridinium bromide hydrate was employed as an adsorbent to remove tetracycline from the aqueous solution. </span></span></span></span></span></span><br>

Adsorbent structural features were analyzed using FESEM, pH of zero point of charge (pH<sub>ZPC</sub>), and Fourier transform infrared spectroscopy (FTIR). Finally, isotherm and kinetics of the adsorption process were studied.</span></span></span></span></span></span><br>
