Erythromycin molecules are resistant in the environment due to the structure of its aromatic-ring that makes it hard to remove or degradation. Nowadays, the presence of ERY in water and wastewater has been reported are above the standard level in various researches. Therefore, the removal and degradation of residues of ERY from wastewaters is important. The magnetic activated carbon is fabricated from Gogan almond shells and characterized and then applied to removal erythromycin from wastewater and water. Several techniques such as XRD, SEM, TEM, Raman, VSM, TGA, and BET were applied to characterize the adsorbent (MAC). Four important factors of sorbent weight, contact time, initial drug concentration, and temperature were optimized by the Response Surface Methodology technique. The maximum adsorption of 95.125% is attained at the initial drug concentration of 65 mg L^-1, sorbent weight of 1.55 g L^-1, the contact time of 76.25 min, and at the temperature of 35 °C. The results show that the experimental data exhibits the best agreement with the isotherm model of Freundlich. In the kinetics study, the experimental data fit well to the kinetic model of pseudo-second-order. The calculated thermodynamic variable factors designated that the adsorption of erythromycin on magnetic activated carbon is endothermic and spontaneous. Finally, the outcomes of this study display that the magnetic activated carbon from Gogan almond shells is an efficient and effective reusable sorbent for the erythromycin removal from the wastewater.

红霉素分子的芳香环结构使其难以去除或降解，因此对环境具有抵抗力。如今，在各种研究中已经报道了水和废水中ERY的存在都超过了标准水平。因此，从废水中去除和降解ERY残留很重要。磁性活性炭是由Gogan杏仁壳制成的，经过表征，然后用于去除废水和水中的红霉素。几种技术（例如XRD，SEM，TEM，拉曼，VSM，TGA和BET）用于表征吸附剂（MAC）。响应表面方法技术优化了吸附剂重量，接触时间，初始药物浓度和温度的四个重要因素。最大吸附95。^-1，吸附剂重量为1.55 g L ^-1，接触时间为76.25分钟，温度为35°C。结果表明，实验数据与Freundlich等温线模型具有最好的一致性。在动力学研究中，实验数据非常适合拟二阶动力学模型。计算出的热力学可变因素表明，红霉素在磁性活性炭上的吸附是吸热的和自发的。最后，这项研究的结果表明，来自Gogan杏仁壳的磁性活性炭是一种有效，可重复使用的吸附剂，用于去除废水中的红霉素。
