The present work determines efficiency of domestic food waste like tea waste in removing pharmaceutical waste such as ceftriaxone (CEF) from synthetic wastewater. Carbonaceous material; Tea waste activated carbon (TAC) has been employed and it showed high removal capacity of 787.5 mg/g. TAC was characterized using; XPS, XRD, SEM, FT-IR, and BET as well as it approved that the adsorbent a has high surface area of .6 m²/g. Various experimental parameters are evaluated for the removal efficiency of the synthesized adsorbent under the present study. During the adsorption study through batch experiments, it approved that the adsorption isotherm was fitted to Langmuir, while kinetically fitted to pseudo-second-order; the adsorption process was chemisorption process as the adsorption energy was 23.7 kJ mol⁻¹. From evaluation thermodynamic parameters the adsorption reaction was endothermic and spontaneous reaction. The different real samples spiked with CEF and studies the efficiency of TAC to remove it. On the other hand, investigated the regeneration efficiency of the TAC and exhibit high regeneration efficiency as it will be used after four cycles with good efficiency of about 84.2%.

农产品废弃物活性炭增强水中头孢曲松抗生素的吸附

目前的工作确定了家庭食物垃圾（如茶渣）从合成废水中去除药物废物（如头孢曲松（CEF））的效率。碳质材料；采用茶渣活性炭（TAC），其去除能力高达 787.5 mg/g。TAC 的特征是：XPS、XRD、SEM、FT-IR、BET等均证实吸附剂a具有0.6 m ² /g的高比表面积。本研究评估了各种实验参数来评估合成吸附剂的去除效率。通过批量实验进行吸附研究，证实吸附等温线符合Langmuir，动力学符合准二阶；吸附过程为化学吸附过程，吸附能为23.7 kJ mol⁻¹。从热力学参数评价吸附反应为吸热自发反应。不同的真实样品中添加了 CEF，并研究了 TAC 去除 CEF 的效率。另一方面，研究了TAC的再生效率，并表现出很高的再生效率，因为它将在四个循环后使用，效率约为84.2%。
